Tokamak cooling system | Final design achieved

ITER - ma, 22/01/2018 - 17:14

To remove the heat from the components closest to the plasma, the tokamak cooling water system will rely on over 36 kilometres of nuclear-grade piping and fittings as well as a large number supports, valves, pumps, heat exchangers and tanks—all integrated into the limited space of the Tokamak Complex. The way has now been cleared for the fabrication and assembly of this complex system, after a final design review was held successfully held in November for the elements that need to be in place by First Plasma.   At your home, water is delivered to the tap at a flow rate of 0.1 m³/ second, a velocity of 1 metre/ second, and at a pressure of around 3.5 bars. 
In contrast, the water will surge through the pipes of ITER's tokamak cooling water system (TCWS) at a flow rate of 5 m³/second, a velocity of 10 metres/second, and a pressure of 14 bars (up to 50 bars at the pump outlet).
The TCWS is a one-of-a-kind nuclear system that is similar in complexity and scope to the cooling systems in a commercial nuclear power plant but—because of the unique design architecture of the machine—is much larger in size. The cooling system will have the capacity to remove up to a gigawatt of heat from the Tokamak. (For perspective, a gigawatt—one billion watts—provides enough power for the needs of a small city.) The TCWS will also provide capabilities that are not used in power plants, such as baking and drying in-vessel components, leak detection, and tokamak maintenance. The system will interface with the secondary cooling system, provided by India, as well as with other ITER plant systems.
System layout and design have been challenging for a number of reasons, including limited space, a large number of interfacing systems, and the fact that—as a safety-important system for the containment of radioactive water—TCWS components must comply with French nuclear pressure equipment directives. All 36 kilometres (1,200 tonnes) of piping and fittings, along with 12,000 structural supports, 3,000 valves, and 100 pieces of equipment will all need to be installed in tight spaces inside the Tokamak Complex.
An innovative arrangement was founded in 2013 to ensure that the procurement and integration could be carried out in the most efficient and cost-effective manner possible. While the global responsibility for the TCWS remains with the US Domestic Agency, part of the scope (including final design, and the procurement of piping) was transferred to a US-funded team based at ITER Organization headquarters, which is carrying out these activities on behalf of US ITER.
Moustafa Moteleb heads the Tokamak Cooling Water System Division at ITER. "With a team of fewer than 30 people at ITER Headquarters, we have been able to produce high-quality work ... improving the initial design of the system, reducing cost, and bringing the first-round of components to the required level of maturity. We have been using Earned Value Management from the start to monitor our own performance against the schedule and to track cost savings."
The final design solution proposed by the ITER TCWS team addresses the important issue of the protecting electronics inside the Tokamak from the effect of activated cooling water—an issue that had been flagged at an earlier design stage. Through the use of specialized expertise and precise modelling tools, the team was able to propose a solution that meets all project requirements on safety.
"The design incorporates a configuration that was approved by Director-General Bigot in June 2015, which significantly improved the investment protection of electronics," says Moustafa. "For many areas, the strategy focused on additional shielding, relocation, and/or the qualification of electronics to withstand the harsh environment. While planning for in-service inspection of TCWS components remains a challenge due to the congestion of equipment, worker exposure rates inside the Tokamak are well below acceptable norms in fission plants."
Now the design of the TCWS piping and components has been confirmed—first at a design readiness review held at US ITER in September, followed by two design integration reviews at ITER in October, and finally in a three-day final review in November attended by approximately 40 experts from the ITER Organization, US ITER, and the industry.
The manufacturing of critical components like heat exchangers and pressurizers, expected on site from 2021 on, can begin.
"It is very exciting to be entering this new phase, with a major part of the design behind us and manufacturing contracts planned in 2018," says Moustafa. "The TCWS team at the ITER Organization dedicates this successful final design review for first-phase components to Responsible Officers Jan Berry and Brad Nelson, who have recently retired from US ITER. They have been involved since the system conceptual design, and without their strong contributions over the years we could not be where we are today."
As for the TCWS team at ITER, they have their work set out for them with the design of second-phase components as well as pre-fabrication engineering studies to reduce the amount of pipe welding carried out on site. Pipe installation will begin in late 2019 inside the Tokamak.

ITER: halfway to first plasma

We are expecting to hear more good news from ITER next year. In December 2017, the largest fusion experiment to come had announced the completion of an important milestone: 50 percent of the total construction work through First Plasma is done! The passing of this milestone reflects “the collective contribution and commitment of ITER’s seven Members,” writes Director-General Bernard Bigot in a letter to all participating nations.

  COMPASS upgrade

You know these days that small tweets can contain big news: EUROfusion’s Czech Research Unit receives 31.5 million Euros funding from their Ministry of Education, Youth and Sports in order to upgrade their tokamak Compass. Once the work is completed, the European fusion consortium is considering to test a new way of plasma exhaust, namely the concept of a liquid divertors, in Prague.

  Chinese-European Cooperation developing

The cooperation between European fusion research and its counterparts in China is developing further. In August, representatives from China visited the EUROfusion offices in Garching. They were eager to learn about the setup of EUROfusion’s programme. Some days earlier they had already visited Fusion for Energy’s headquarter in Barcelona. Those meetings in Europe are a direct result from the Technology Management Plan which has been signed at the Fusion Energy Conference 2016 in Kyoto, Japan. The European team is eagerly looking forward to returning the visit. In January, a 24 person large delegation from EUROfusion delegates will be welcomed at the he Chinese Center for Fusion Science of the Southwestern Institute of Physics (SWIP) in Chengdu.

JET as a pictorial record

EFDA - di, 16/01/2018 - 12:00

Painter Sarah Moncrieff has painted a portrait of the world’s largest tokamak. In this interview, she shares her thoughts on “fusing line, colour, mark and texture” with Fusion in Europe.

Why did you choose to paint JET?

I am primarily interested in two things: firstly, what constitutes a person’s daily visual experience. We often become immune to our work environment. We no longer see it with fresh eyes. This feels particularly pertinent in Culham where the structures and colours are extraordinary. My paintings remind us of our everyday surroundings. They also capture a specific moment in the history of our working lives as these environments will undergo change. Secondly, bold shapes, colours and lines appeal to me and I like to derive a sense of order from a visually complex scene.

The choice of colours appears to differ from your usual industry related work.

The bold colours within the work environment of Culham were so strong that I simply could not ignore them. They are a fabulous riot of cadmium yellows, cobalt blues and vermillion reds. It was the combination of the colours and structures that really appealed to me. Had I confined myself to a limited colour palette, I would have lost something fundamental. Instead, the challenge was one of taking the scene and extracting the significant structures and shapes from it in order to achieve a sense of the whole without needing to paint in every element.

UK based Sarah Moncrieff is a painter and concentrates on depicting modern urban life through her Urban Landscape paintings. For more info check out her homepage”: www.sarahmoncrieffpaintings.co.uk

What was painting the machine like?

I started the process by drawing the machine over and over again to make sure I understood the structure. There is nothing more frustrating than realising half way through that you have got a crucial element all wrong. Whilst drawing it, I really engaged with the powerful curves, the intricate details of the structures and the different parts all of which connect to create one amazing machine.

The act of painting is the creation of something, but instead of fusing nuclei to create energy, I am fusing line, colour, mark and texture to create my final piece.

I then had to think about what parts of the machine itself I should paint and what parts I should leave out. This is a constant struggle for me as an artist. I need to retain enough to convey the essence of the machine itself, but I don’t want to paint every tiny detail, otherwise I might just as well take a photograph. Painting is a process of saying as much as you can but as concisely as possible.

EUROfusion buys experimental time on an overall of six different fusion machines in Europe. Would you be interested in painting any more?

I am very interested. Presenting a series of paintings of machines and environments at the forefront of technology would be an exciting and stimulating challenge. Scientists will record the progress and results of this journey, but as an artist I can make a pictorial, historical record.

Alternative Fusion Concepts: Helion Energy

EFDA - di, 16/01/2018 - 11:58

Fusion research benefits from its variety of labs and approaches. Not all of the ideas and concepts belong to EUROfusion or publicly funded research. Private companies, even far beyond European borders, are also trying to bring fusion energy to life. In this series, Fusion in Europe introduces different approaches and provides an outline indicating what is hidden behind catchyclaims designed to attract the attention of investors. This time, we introduce Helion Energy.

1. Facts

2. Idea

click to enlarge!

Helion Inc. is a spin-off of MSNW LLC, a company that is developing space propulsion technologies, including fusion plasma thrusters based on the Helion concepts. Helion uses Magnetised Target Fusion. Their “Fusion Engine” is similar to a diesel engine with electromagnets replacing the pistons. It is based on Field Reversed Configuration (FRC), created by an initial axial magnetic field rapidly reversed by a purely toroidal Theta Pinch current, diamagnetically balancing the plasma pressure gradient. Twin plasma guns fire opposing FRCs to coalesce in a central burn chamber. Here the deuterium-helium3 plasmoid is rapidly magnetically compressed. It fuses and the expanding particle energy is directly converted to electricity by reacting on the magnetic field, pulsing at up to 10Hz.3. Opinion

Tom Todd joined the Culham Science Center in 1975 prior to a one-year secondment to the DIII-D tokamak at General Atomics. He has also served on many design reviews for European devices, including ITER, and beyond. In 2004, he became Chief Engineer at Culham and was appointed Chief Technologist in 2011. After retiring in 2014 he became a fusion consultant and an MSc course lecturer for several universities. Picture: private

FRCs have been under investigation since the 1960s but they did not achieve high performance plasmas. They have some asymmetric instabilities and the full effects of the fusion products are unknown. The plasma confinement time is about 50% of the ~1ms pulse length. Reactor efficiency thus requires an unusually high plasma density and temperature.Directly converting the energy of all the fast ions is problematical, especially since electromagnetic radiation and fast ion losses will decrease the useful power output by approximately 30%.The fuel is also a challenge: a 70MWth reactor burns approximately three kilograms of 3He pa. Helion would need about 25kg of tritium stock (equal to the world’s civil stock today) to create just half its 3He fuel by decay. Helion’s plans to demonstrate a 50 MWe power plant in about three years from now must also cover developing the Direct Energy Conversion and

Fusion en Marche!

EFDA - di, 16/01/2018 - 11:58

French-Lebanese physicist Farah Hariri and French President Emmanuel Macron have something in common: they are young, enthusiastic and willing to change the world. Just one year ago, Farah joined Macron’s movement En Marche! Now, while candidate Joachim Son-Forget has become the deputy representative for French residents in Switzerland and Liechtenstein, his team member Farah has been nominated coordinator for developing the energy agenda in Switzerland and ITER is part of the plan.

“Being interested in our collective future is simply in my genes, in my family”, Farah admits. Macron’s revolutionary approach to gathering experts from different political parties and professions seemed just made for her. “With Emmanuel Macron, we will make a difference, we will make our planet great again!”, she states with a smile.

Implementing energy theory

One of her top priorities is the reduction of greenhouse gas emissions while providing a reliable and safe energy supply. Born in Lebanon, energy issues used to be part of her daily life. “Daily power outages were a norm”, she explains. Being also very keen on maths, she decided to study plasma physics at the American University of Beirut. After graduating, she went to do a doctoral scholarship to CEA (Commissariat à l’énergie atomique et aux énergies alternatives). Her fusion career seemed unstoppable. She authored a thesis on the Flux-Coordinate Independent (FCI) approach, which opened the way for the numerical simulation of plasma turbulence in a tokamak, a necessary code to address the transition from the low (L) to the high (H) mode of energy confinement, a yet still unexplained phenomenon. ITER, as it happens, needs to operate in the H mode to achieve the expected fusion performance.
In 2013, her thesis work won the 9th Itoh prize in Plasma Turbulence and the PhD prize of Aix-Marseille University. Farah continued on her career path with a post doc position at the Swiss Research Unit SPC (Swiss Plasma Center), but then CERN called.

All available combinations to avoid fossils

She joined the famous lab in 2016 and was assigned to focus on theoretical modelling: “The idea of predicting what happens in the world’s largest particle accelerator was simply thrilling, a noble opportunity which I could not let go”, she says. So much for the theory…
In her spare time, she has actively participated in the campaign of Emmanuel Macron. Today, she is coordinating the energy transition agenda for En Marche in Switzerland where multi-national projects all have different milestones, including future energy scenarios. “The timescale to fight climate change is short. We should zero out greenhouse gas emissions by 2050 so that the two-degree threshold is not crossed. At the moment, we are in a transitional phase which does not yet have a sustainable solution. We need to use all available combinations to move away from a carbon-based energy economy”, Farah says.

Fusion is the leading option in the future energy mix

She is aware that commercial fusion energy will not be part of combating climate change during the first half of the century: “But when it comes to long term sustainability, ITER and fusion energy is one of the leading, most interesting options for a sustainable energy mix”, she says. According to her, the question is not IF but WHEN fusion will be rolled out. “On a global-scale, replacing fossil fuel while guaranteeing a constant baseload for our electricity supply means we need to incorporate all advanced nuclear solutions, including fusion.”

ITER – a matter of urgency

For Farah it is a matter of urgency that fusion appears on the energy transition agenda. To her, a successful demonstration of ITER’s burning fusion plasma is needed as soon as possible: “We’d like to see the successful operation of ITER as soon as possible, this is an emergency. Any further delays to this are very damaging. The turning point will be the demonstration of a significant energy amplification in ITER. After this phase, private companies will undoubtedly consider developing what we need: smaller and cheaper fusion power plants”, Farah states.
She also believes that the success of a numerical virtual tokamak is essential during this phase. “The successful operation of the ITER machine is important. But I believe that the success of a Numerical Virtual Tokamak is equally important. Being able to model and simulate the full machine is as important as the operation of the machine itself.

In the wake of Macron and Hulot

During the One Planet Summit organised by the French President on December 12 in Paris, two years after the historic Paris Agreement was concluded, Farah had the chance to discuss ITER’s future impacts with Emmanuel Macron and Nicolas Hulot, French Minister of Ecology.

The desire to end the Cold War led to the launch of ITER. ITER being the largest international project worldwide that enables involved workers, whether originating from science or industry, to better understand the cultural diversity of the participating countries. […] France thanks the Commission for its resolute action in support of the ITER project and also hopes that {…} the European Parliament will continue supporting the project. In conclusion, I would like to emphasise how ITER, to me, is a unique human, scientific, technological and industrial adventure requiring a perfect cooperation on all these plans. You can count on the support of France”, Frédérique Vidal, French Minister of Higher Education, Research and Innovation in a speech on 4th December 2017 within the framework of the ITER Industry Days

Along comes a SPIDER

EFDA - di, 16/01/2018 - 11:57

Did you actually think that all ITER parts are located at Cadarache, France? Well, no. PRIMA (Padova Research on ITER Megavolt Accelerator) is located in Italy. It will test the neutral beam heating for the world’s largest tokamak to come. All of PRIMA’s components, one of which goes by the name SPIDER, belong to the ITER Organization. Why does it need another complex multinational experiment to finally turn the big tokamak into a success? It is a matter of dimensions.

Representatives of F4E, Thales and RFX standing in front of the SPIDER beam source. Picture: F4E

“The heating injectors need a performance which is magnitudes above current applications”, says Tullio Bonicelli, responsible Project Manager at Fusion for Energy (F4E). Hence, it seems quite appropriate to test them before they will be finalised in the world’s largest fusion experiment.

Negative ion beams

Powerful beams of neutral particles heat the fusion plasma. Usually, positive ions are accelerated and then neutralised before injection. [see also the article about the helicon plasma source on page XX of this issue].
The ITER Neutral Beam system will use negative ion beams, because the efficiency of neutralising positive ions declines heavily as the beam power increases. Such beams have unprecedented energies of one mega-electron volt (MeV) and they are on for a much longer time (up to one hour) than today’s systems. Each of the two injectors that are currently planned for ITER will transmit 16.5 Megawatt of power to the plasma.

See also the model of Neutral Beam Injection here: https://www.euro-fusion.org/?p=267239

To tackle the challenge of unknown heating dimensions, PRIMA comprises two independent test rigs: The negative ion source SPIDER (Source for Production of Ion of Deuterium Extracted from radio frequency plasma) produces hydrogen and deuterium ions and accelerates them up to 100 kilo-electron volt. MITICA (Megavolt ITER Injector Concept and Advancement), a first full-size and full performance ITER injector, accelerates these ions up to 1 MeV.

Teaming up in Europe, India and Japan

Of course, such efforts can’t be done by one country alone. Tullio Bonicelli describes the team work: “F4E provides important funds to activities under the Neutral Beam Test Facility Agreement. EUROfusion member Consorzio RFX and Italy have provided the buildings and some infrastructure as well as contributing, in a substantial way, to the technical and scientific manpower. The Indian and Japanese agencies from F4E, responsible for ITER, are also making their contributions by delivering important components.

ELISE pioneered for ITER

Research carried out at third parties has also played a major role: the German Max Planck Institute for Plasma Physics has been investigating negative ion sources for years. In fact, their heating source in the ELISE (Extraction from a Large Ion Source Experiment) test rig became the prototype for the ITER system. The device in Garching was half the size of the the one planned for ITER. ELISE produces a particle beam with a cross-sectional area of about one square metre.
SPIDER will start spinning during the first half of next year. MITICA is scheduled to follow in 2022. The experiments that will be carried out after the successful launch are needed to fine-tune the present injector design for ITER.

PRIMA is immense and features many mysterious names. ITER‘s Neutral Beam Test Facility in Padova will switch on the light in the first half of 2018. Take a tour through MITICA and SPIDER before they get busy.

Interview with Tullio Bonicelli, Project Manager for Neutral Beam and Electron Cyclotron Power Supplies and Sources at Fusion For Energy

What is the economic impact on the PRIMA facility for European companies?

Many companies have been involved in our contribution to the PRIMA facility, such as OCEM ET, COELME, Thales, Zanon, CECOM, Galvano-T, Siemens, DILO, De Pretto, NIDEC, Angelantoni, Delta-T and many important sub-contractors such as Himmelwerk, HSP or Andreas Karl. The cumulative value of the contracts that we have signed is in the range of 120 million Euros.

What does it mean to build this large device while cooperating with Consorzio RFX and Domestic Agencies in India and Japan?

In a nutshell, the Neutral Beam Test Facility in Padova is very similar to ITER, from an organisational point of view. Some root issues are therefore also common, like the separation between design authority and financial or contractual responsibilities. The decision-making process may become cumbersome and long, introducing in itself risks of additional delays and costs. The successful execution therefore needs collaboration, a certain degree of flexibility, a lot of pragmatism, and, crucially, the common drive of all partners towards the final objective.

Is there anything F4E has learned for the project management at ITER?

There is one main conclusion to be drawn and that applies to all parties – the principle of collaboration. It pays off in spite the additional interfaces that unfold in the process. We learn to listen to one another, manage the project together because we are responsible for its different components, and last but not least, we get to capitalise on a wide set of skills.

Will ITER, in the end, be flexible enough to adjust to the results found at PRIMA?

Yes. There is full confidence that the present lay-out of ITER’s heating source, will be able to accommodate the modifications coming from the PRIMA test beds.

F4E: we need to act as one!

EFDA - di, 16/01/2018 - 11:57

Fusion for Energy’s (F4E) Director Johannes Schwemmer settles down at the end of a busy week. Just a few days ago he was attending the ITER Industry Day at the European Commission’s headquarters, the Berlaymont building, in Brussels. The event held by the European Commission was just one of two major events to celebrate the 10th anniversary of F4E. The organisation manages the European industrial involvement in the world’s largest tokamak to come. Ten years of ups and downs in the history of ITER have resulted in numerous lessons learned.

Mr Schwemmer, F4E is celebrating its 10th anniversary this year. To what extend has the industrial engagement for ITER changed throughout that period?

“We have been collaborating with at least 400 European companies and 60 research entities in more than 20 countries at a cost in excess of four billion Euros. It surely is a successful development for the European industry, although we also need to restore our reputation due to ITER’s management crisis in 2013. At the ITER Industry Day, we heard many industrial partners saying that they are proud to undertake this endeavour with us. They feel they are a part of delivering this new energy.”

You became F4E Director in 2016. How have you improved efficiency and business optimisation since then?

“Of course, the public tendering processes are still considered ‘an adventure’ for some of the smaller industrial partners, as one speaker at the ITER Industry Day has put it. F4E began as a start-up dealing with contracts worth billions. We clearly needed to improve the speed and efficiency of processes, for example, recruitment and procurement. You cannot define projects by only following the rules without even tracking the time it takes until you deliver the result. We applied a new methodology thanks to which we have managed to become faster and more efficient.”

Many critics argue that it is hard for a small or mid-sized company to overcome the barriers in order to bid on a complex international project like ITER. What does F4E do to support applications?

“We are indeed relying on small and highly specialised companies to contribute to ITER’s components. It is therefore important to cut down the large subsystems into smaller contracts to encourage the participation of all business partners.”

To what extend are you taking advantage of experiences made in other multinational projects, such as the European Space Agency?

“We have staff members from the Joint European Torus (JET), CERN or the European Space Agency and we are, without a doubt, making good use if their expertise. This year, in fact, we have also held an international engineering best practice workshop in which we focused on benchmarking of processes and the results of those projects.”

What separates ITER from those projects?

“There is one very important and very special condition for ITER and that is the fact that ITER is a nuclear facility. Design, assembly, commissioning, construction, operation and decommissioning must comply with French laws and regulations for licensing. Every part, every design and any change must be authorised by France’s Nuclear Safety Authority.”

How would you define EUROfusion’s future role in realising fusion projects?

“European fusion science is very attractive to partners outside Europe, be it China or Japan. They would like to cooperate. But with whom could they possibly talk when they want to talk to Europe?
It is crucial that F4E, EUROfusion and the respective departments in the European Commission act as one towards those future partners, otherwise we won’t be able to take full advantage of our rich expertise. We are taking steps, with EUROfusion, to develop a closer cooperation. We have played a vital part in developing the European Fusion Roadmap and we have also succeeded in discussing diagnostic aspects. I am really looking forward to realising the joint project on the Test Blanket Modules.”

How would you define the special tasks for EUROfusion and F4E?

“To me, this is relatively clear. F4E is building the machines, we are neither responsible for operation nor research. EUROfusion is carrying out the research and engaging in the preliminary design studies; subsequently it joins the commissioning of the machines in order to take the lead in running them to conduct research. As a result, we need a close collaboration between both organisations.”

You say that EUROfusion does research and inital design studies in order to develop machines. What is it that science can learn from industry?

“I believe it is important that a professional engineering process should be also respected throughout the period of design. We are developing a complete and highly complex machine and the manufacturing process needs to be taken into account from the outset. In the end, this will save time and money.”

How do you sell the ITER project to a company?

Innovation, reputation and motivation: first of all, the company has the opportunity to learn new techniques in new dimensions and to apply those skills to upcoming projects. The reputation gained from working on a project like ITER and the motivation for the staff members are also benefits. Project management has been one of the main challenges of the project. Due to constant changes in design, we had difficulties in launching the necessary calls for tender. Since Bernard Bigot took office and remarkably changed the project management culture at ITER, we are much better at realising the contracts and we can continuously report on our progress in a positive way.”

ITER is not the only project F4E is building with the help of European companies. What is a project that you are really looking forward to in terms of realisation?

“We are really happy that the Japan Torus 60 Super Advanced (JT-60SA) is scheduled to deliver its first plasma in 2020. It is the most modern JET-sized tokamak. It is located in Japan and we are eagerly looking forward to hand it over to Japanese and EUROfusion scientists.”

What do fusion and food-packaging have in common?

EFDA - di, 16/01/2018 - 11:56

“You know, you have this good idea on paper, but it needs practical proof”, says Philippe Guittienne. The physicist has founded his own company “Helyssen” as a spin-off from the Swiss Plasma Center in 2003. A medical application inspired him to re-think plasma sources. Today, his antenna might not only revolutionise food-packaging but also fusion plasmas.

Philippe says it was a matter of luck. By the time he was about to finish his PhD thesis in 2002 he met someone, by chance, who was looking for entrepreneurial ideas. “While searching information on different plasma sources I found a theoretical study about helicon waves. The pattern reminded me of the field generated by the ‘birdcage’ antenna which is commonly used in Nuclear Resonance Imaging.”

All about plasma

Philippe signed a research project with the French company Alcatel. Since he, back then, had no experience with plasma research he collaborated with the Swiss Plasma Center (SPC, at the time called Center for Research in Plasma Physics). The lab enabled him to test his ‘birdcage’ antenna for producing helicon plasmas; plasmas that are highly desired in various fields. It is not only the food-packaging industry that is interested (see information box) fusion research was also eager to investigate Philippe’s new plasma source.

One of the most common ways to heat plasma is via Neutral Beam Injection (NBI). The trouble with this is the small wall-plug efficiency of this method, which will have to be maximised in a future fusion reactor.

NBI involves four stages (see illustration above). Stage three of the process is the neutralisation of the charged ions. The usual way is to accelerate positive ions. Recombining the ions with electrons neutralizes them in stage three. This neutralisation may cause the loss of ions.
For ITER, the neutral beam injection will use negative ions. One of the proposed solutions in order to avoid ion loss is photo-neutralization, in which photo-detachment is used to strip the electrons from the ions, thus neutralising them. But, this method requires a very special type of plasma in the ion source, in the shape of a long and thin column.
In fact, the required precise plasma shape is difficult to realise. And this is where Philippe’s birdcage antenna comes in. Its induced waves generate the required negative ion-rich plasma column. “The helicon source proved very efficient for high-density plasmas with moderate injection power”, says Ivo Furno from SPC who has worked with Philippe for some years now.

New dimensions in France

Both now aim to take this approach to new dimensions. In conjunction with EUROfusion’s French Research Unit CEA in Cadarache, they are currently developing a 10 kW helicon plasma generator for neutral beams (NB) for the next generation of fusion devices. The larger helicon source will be installed in the Cybele device at CEA which tests the photo-neutralisation of negative ion beams.

A marketing boost

It remains to be seen if Philippe’s idea will improve heating scenarios for future fusion devices. His example further shows how scientific requirements can be converted into industrial reality. “Industry is able to supply research with practical know-how, tools and manpower”, says Ivo. But it is considerably hard for small and middle-sized enterprises participate in such complicated research areas and also, get their foot into the door of multinational and complex projects such as ITER or DEMO. “I think, first of all, you really need the knowledge to understand what the researcher needs from you”, says Philippe. “Once you have you get it done in practice you have a great selling point. Your application has been included in a Big Science Project which is a huge marketing boost when engaging with future clients”, says Philippe.

Helyssen and Tetra Pak: How to un-spill the milk

Helyssen is also collaborating with the Tetra Pak Processing GmbH. This is the company that puts milk into small cardboard boxes. The packaging material is made of paper but must also be water-proof and a barrier for oxygen. Hence, it needs to be coated with a special layer. The aluminium foil currently applied onto the surface of the packages means that the package is non-disposable. Therefore, Tetra Pak is looking at environmentally friendly solutions which need different application techniques. Here is where Philippe’s plasma application comes in. It is able to precisely deposit the very thin, about 10 nm, barrier coatings on the plastic foils. This technique could finally help to improve the environmental disposal of such boxes.

A lot of good neutron science

EFDA - di, 16/01/2018 - 11:56

Scientists at the Joint European Torus (JET) have been working feverishly to prepare experiments which allow the improved measurements of neutrons for the planned tritium (T) and deuterium-tritium (DT) campaigns. Those experiments are scheduled in 2019 – 2020 but the preparations have been ongoing for years now. The fusion experts have developed new detectors which are already in place to study the neutron streaming through penetrations in the biological shield and to investigate the activation and damage they induce in the material. Such observations are of extraordinary importance for ITER because they can prove that the tools used in the ITER design are valid and appropriate.

We will be ready!

“I was excited to see the results achieved this year, we produced a lot of good neutron science. Also, after a considerable preparatory effort, we will be ready for the T and DT campaign” says Project Leader Paola Batistoni. One of the most important achievement is the calibration of JET neutron yield monitors at 14 MeV neutron energy. She admits that it has been quite challenging to insert a neutron generator inside the JET tokamak with the help of the remote handling system, to calibrate the neutron detectors. This came with the complex equipment of active detectors, power supply units, and electronics. However, the measurement accuracy in the calibration is better than the target value of ten percent.

Gaining experience for ITER

Additionally, neutron detectors have been installed around the tokamak. They have already provided time dependent measurements of dose rates during operation and in the following shutdown. The preliminary results of the first simulations show that the calculated shutdown dose rate is in remarkable agreement with measurements. More than sixty scientists have discussed those notable results during the Annual General Meeting of the JET DT Technology Project at the end of this year. Among those experts were representatives of fusion organisations worldwide such as Mike Loughlin (Nuclear Integration coordinator in ITER), Dieter Leichtle and Marco Fabbri (Nuclear Integration coordinators in F4E) as well as Robert Grove and Scott Mosher from Oak Ridge National Laboratory and Tim Bohm from the University of Wisconsin Maddison.

Team excitement was palable

At times during the meeting the team excitement was palpable because we finally see that the initial effort is producing a good harvest”, concludes Paola.

Win-win: real-time collaboration between ITER and JET

EFDA - di, 16/01/2018 - 11:56

Our motivation was to set up a better infrastructure in order to focus on turning fusion energy into reality”, says Adam Stephen from the Culham Centre for Fusion Energy (CCFE). He teamed up with partners from ITER and Fusion for Energy to modernise parts of JET’s central nervous system with the help of ITER’s software.

Adam is part of the team which delivers CODAS. This COntrol and Data Acquisition System uses a real-time network which interconnects more than 100 systems receiving data from and feeding data into the Joint European Torus (JET). The device’s communication system was due for an upgrade so that it would accept current state of the art communication.

In the front (left to right) Danny Sortino (Student), David Grist (Visualisation team), Adam Stephen (ITER systems I&C coordinator for JET). Pictures: A. Stephen

Real-time visualisation

The question was: is there already a facility that has the proper software toolkit to enhance world’s largest operational tokamak? The answer came as a surprise: ITER, the tokamak of the future. An important part of the modernisation comprised improved visualisation tools for the scientists in JET’s control room. In practice, JET data are piped into a new real-time visualisation system integrated by Derek Sandiford and colleagues. As a result, the team in the control room now benefits from an improved view of the tokamak processes displayed on their screens.

“I would say one of the nicest part of our ITER software is the real-time communication, a combination of networks and software”, says Anders Wallander, Head of ITER’s Control System Division. Imagine you need to run a unique fusion machine which needs to manage the input of 170 different plant systems and, moreover, make this data available to the world’s scientific community as quickly as possible. You don’t start developing it just two weeks before going online.

Increasing ITER’s user community since 2011

On the contrary, the ITER CODAC software development was launched in 2011 and made available to the whole fusion community. Over 65 organisations such as plant system suppliers, fusion labs, domestic agencies and contractors are currently using the software in order to develop plant control systems, test and evaluate them and give feedback. Just like any other software, on your smartphone for instance, the software is updated every so often. “It is stable now. This year, we switched from two updates per year to only one”, says Anders.

Only three days to go

For this, ITER provides digital customer support along with the infrastructure. As the ITER plant systems are currently in the manufacturing phase it is difficult to comprehend how well they will work in an integrated machine.
The situation at JET, which has been up and running since 1983, was different. “We were able to test in reality to see the ITER software was mature enough and we could focus on the real challenge”, says Adam Stephen.
Adam and his counterparts Bertrand Bauvir (ITER) and Andre Neto( Fusion for Energy) were literally able to go into a closed meeting for three days and integrate the entire system until the late evening: “We had all preparations done and then went into a workshop where we fixed every tiny issue. The goal was to get the system going within three days and we succeeded in a fairly short time!”

Communication matters

“This only works if you have the right people, the right timing and the right solution for the problem”, says Anders Wallander. He and his CCFE colleague Adam agree on defining the most important thing for a fruitful collaboration: communication. “Usually, you have technical experts but they are not so good in communication. Or you have good communicators but they lack technical expertise. You hardly ever get both”, says Anders.

In this case, the project team obviously managed to obtain all the necessary skills. The group is eagerly looking forward to continuing with the successful integration of ITER’s software on JET’s system. This co-operative work is a win-win for both the experienced tokamak in England and the one to come in France. By choosing to work together, it also makes it possible for future ITER prototypes to be seamlessly tested on JET.

Vacuum vessel | First segment completed in Korea

ITER - ma, 15/01/2018 - 16:26

The technically challenging fabrication of the ITER vacuum vessel is progressing in Korea, where Hyundai Heavy Industries has completed the first poloidal segment for sector #6. From manufacturing design and material procurement to cutting, forming, machining, welding, non-destructive examination, and final dimensional measurements—the industrial effort to forge the building blocks for ITER's double-walled steel plasma chamber is one of the most complex of the ITER Project.  

On 11 December 2017, Hyundai Heavy Industries (HHI) completed dimensional checks on the inboard (poloidal) segment of vacuum vessel sector #6—the first-completed segment of the vacuum vessel construction program.
All inspection and test results demonstrated that safety requirements are fully satisfied and that the tolerances of the completed segment, measured at ± 4.0 millimetres, are well within the ITER requirement of ± 10.0 millimetres.
With this successful realization the ITER Project celebrates both an industrial and a programmatic milestone, as the first production unit is the result of a lengthy program to establish, qualify and implement manufacturing and test procedures for a one-of-a-kind component, and also respects the calendar of ITER Council milestones that has been established to track project progress.
"It was very challenging to reach this level of technical maturity and achievement," says Wooho Chung, the technical responsible officer for the vacuum vessel at ITER Korea. "Because the vacuum vessel will act as the first safety confinement barrier, all of our procedures and activities had to be qualified and approved by the Agreed Notified Body (a company authorized by the French Nuclear Regulator to assess conformity of components in the pressure equipment category, ESPN)."
Since signing a Procurement Arrangement with the ITER Organization in November 2008, teams in Korea have developed—and received authorization for—detailed manufacturing procedures for forming, welding, and non-destructive examination (especially ultra-sonic examination and remote visual examination).
"After successfully completing the manufacture of the first poloidal segment, we will now be able to move more smoothly on the basis of confirmed manufacturing processes and procedures," states Chung. "We know that we have still remaining challenges—such as the completion of the outboard segments for sector #6 as well as factory acceptance tests—but we are confident that we can achieve these steps this year."
The ITER doughnut-shaped vacuum vessel will be welded in the Tokamak Pit at ITER from nine steel sectors. Each 40° vacuum vessel sector is a double walled steel component weighing 500 tonnes and measuring 12 metre in height and 7 metres in width, with multiple port openings and in-wall shielding contained within its walls in the form of modular blocks.
Key to the good progress on the challenging procurement of the vacuum vessel, according to Chung, is very constructive and cooperative collaboration between the members of the Vacuum Vessel Project Team and industries.
Fabrication responsibility is shared by four ITER Domestic Agencies—Europe (five main vessel sectors); Korea (four main vessel sectors plus equatorial and lower ports); Russia (upper ports); and India (in-wall shielding)—plus the ITER Organization and a large number of industrial contractors. The Vacuum Vessel Project Team was created to make one team of these participants for promoting synergies, the sharing of experience, and the rapid resolution of fabrication issues.
Collaboration meetings among participants of the Vacuum Vessel Project Team are organized regularly; (please see the report of the latest meeting on the European Domestic Agency website). All vacuum vessel components are currently being manufactured with good quality assurance and quality control at various industrial locations worldwide.
With the results achieved for the first segment, Hyundai Heavy Industries has identified how tolerance control can be improved for the next segments through experience. The results are also undergoing detailed, integrated analysis at the ITER Organization Design & Construction Integration Division, taking into account all interfacing systems.
The Korean Domestic Agency plans to complete the first sector (#6) and start the mass production of all remaining sectors/ports in 2018.

First toroidal field coil structure | Submillimetric tolerances achieved

ITER - ma, 08/01/2018 - 18:05

In major news for the ITER superconducting magnet program, the first toroidal field coil case has passed all fitting tests. The two sides of the huge component—as tall as a four-storey building and machined from 20-centimetre-thick steel—were matched within gap tolerances of 0.25 mm to 0.75 mm, an accuracy of more than one order of magnitude in relation to conventional high-precision welded structures of comparable size.
On 18 and 19 December 2017, precision laser trackers were used to measure the alignment of inboard and outboard legs of the first toroidal field coil case as well as the precise position and orientation of the heavy steel segments. The measurement results were sent electronically to the ITER Organization for detailed analysis, where it was confirmed that giant steel structures matched at all welding grooves with gaps ranging from 0.25 mm to 0.75 mm, fully respecting specified tolerances.
"This is a technological achievement of the highest order," declared Eisuke Tada, ITER Deputy Director-General, as he attended a ceremony on 26 December at the testing site. "A component that is 16 metres in height, weighing 190 tonnes, has been successfully machined to within sub-millimetre tolerances by multiple manufacturers. The international nature of this achievement makes it all the more remarkable."
The toroidal field coils cases provide protective covers for the toroidal field winding packs, the superconducting core of the magnets wound from approximately 5.5 kilometres of niobium-tin conductor. The thick steel cases also have a structural role to play, anchoring the poloidal field coils, the central solenoid and the correction coils and withstanding huge electromagnetic loads inside the machine.
Japan* is responsible for producing 19 toroidal field coil structures (for ITER's 18 toroidal field coils plus one spare). Nine of the structures will encase the toroidal field coil winding packs produced in Japan, while ten—including this first unit—will be shipped to Italy for the insertion of winding packs produced in Europe.
Toroidal field cases are D-shaped components, with the inboard leg corresponding to the straight-backed portion of the letter and the outboard leg corresponding to the rounded portion.
The inboard leg of the first coil case was manufactured at Mitsubishi Heavy Industries, Ltd. (Kobe, Japan). During fitting tests in July 2017 the two sections of the inboard leg—the U-shaped sub-assembly ("AU") that will contain the superconducting core plus a cover plate ("AP")—were successfully paired with gap tolerances of 0.25 mm to 0.75 along the entire 14-metre-long weld groove.
The outboard leg was contracted by Japan to Hyundai Heavy Industries in Ulsan, Korea. The ultimate test was then to verify that structures manufactured in two locations following stringent ITER Organization specifications would fit together perfectly. "Ultimately, the story of the toroidal field coil cases is the occasion to showcase the spirit that underlies the ITER Project in its entirety—the "One-ITER" spirit of teamwork that unites us around one design, one schedule and one mission," stressed Deputy Director-General Tada.
At Hyundai, the outboard leg sub-assemblies ("BU" and "BP") were first fitted together to verify manufacturing precision. Then, on 18 and 19 December the principal segments of the coil case ("AU," manufactured in Japan and shipped to Korea, and "BU" manufactured in Korea) were positioned and measured. (Please see the photo gallery below for further explanations.)
The required tolerances of bevels at the welding grooves were respected across the board at less than 1 millimetre—with gap variations ranging from 0.25 mm to 0.75 mm. Witnesses on hand during the fitting tests included representatives of the ITER Organization, the Japanese and Korean Domestic Agencies, the European Domestic Agency (which will be receiving the component), and manufacturers Mitsubishi Heavy Industries and Hyundai Heavy Industries.
The successful fitting trials of the first toroidal field coil case demonstrates that the final assembly—the insertion of the superconducting winding pack followed by closure welding—can be achieved within the tight tolerances required. This is excellent news, as work proceeds on the fabrication and precision machining of elements for the 18 other cases.
The first case is now on its way to SIMIC (Italy), where the first European winding pack has been delivered for insertion.
*QST—Japan's National Institutes for Quantum and Radiological Science and Technology—is responsible for the procurement of all components allocated to Japan by the ITER Organization.

Six postdocs connect tokamak and stellarator

EFDA - wo, 03/01/2018 - 09:00
The Max Planck Institute for Plasma Physics (IPP) in Germany offers unique possibilities. It features not one, but two of the most advanced fusion experiments available. The Greifswald branch hosts the stellarator Wendelstein 7-X and the Garching institute operates the tokamak ASDEX Upgrade. Why not make use of the best of both worlds? For the first time in history, the institute has offered six postdoc positions with the intention to create synergies between tokamak and stellarator research.


The announcement from the Scientific Board of IPP arrived just in time for tokamak expert Rachael McDermott and her stellarator colleague Oliver Ford. Rachael in Garching and Oliver in Greifswald were about to purchase new cameras to observe the plasma inside both experiments. Those cameras came with software which was not ideal for the needs of the two research teams.

Darren McDonald from
EUROfusion’s ITER Physics Department: “EUROfusion’s roadmap brings together tokamaks and stellarators. Sharing of ideas and people between the two areas benefits both. A good example of this is the work being done on the
Wendelstein 7-X stellarator in support of ITER. The new postdoc programme is a great
way to encourage even more collaboration.”

Joining the paths

Developing proper software is not the only thing that researcher Rachael is interested in. “What will be really exciting to see, is how the two different groups of researchers tackle the same problem”, she says. “We usually have the same objectives, but we reach them via different paths. Exchanging and interacting here might create the best solution.”

Two teams, one goal

“We were kicking around ideas regarding how to develop the systems to better meet the goals of our spectroscopy groups”, says Rachael. “If we had the dedicated manpower we would be able to create something specific in a more efficient way and would not have to rely on commercial products that are designed for a more general audience.”
Rachael and Oliver used the newly created research opportunity to launch a call for a postdoc. He or she would become one of the six ambassadors who, from next spring onwards, will travel and work in both the tokamak and stellarator worlds. The person will receive equal training at ASDEX Upgrade as well as Wendelstein 7-X between 2018 and 2020 and will help to create resources that benefit both groups.

Creating extra space

“By allocating postdoc resources to such collaborative projects, we have created space for special projects to flourish. We were very impressed by the quality of the proposals that we received in response to this call”, says Thomas Sunn Pedersen, Director of the Stellarator Edge and Divertor Physics Division in Greifswald.

It is not only the creational aspect that looks promising: “The new postdoc will be in an optimum position to benefit from ASDEX expertise, and transfer this knowledge to the Wendelstein 7-X team. We in Garching have years of practice in running, for example, visible spectroscopy diagnostics and in interpreting the measurements. This will be very useful when the stellarator systems come online”, says Rachael.

Tony Donné summing up 2017

EFDA - di, 26/12/2017 - 09:45

Tony Donné, EUROfusion Programme Manager

I am increasingly convinced that we, in Europe, benefit from the most coherent and best coordinated research programme in the world. As Programme Manager, I have the unique ability to compare fusion research worldwide.

I have heard many scientists from other countries say that they envy us for being able to follow a competitive outline which focuses on very clear priorities. Our plan enables scientists and engineers, from 30 national research laboratories and well over 150 universities, to work together towards the same common goal.

The basis for this is the European Fusion Roadmap which defines the main challenges that will need to be tackled in the coming years. It also describes a detailed research plan. Since its publication in 2013, we have made very good progress on many topics. The change from carbon to metal walls has led to a considerable reduction in hydrogen retention and dust production – very good news for ITER because this implies fewer openings for cleaning.
Moreover, our scientists have developed new operational recipes in order to reach high performance with metal walls, and they have discovered that fast ions have a stabilising effect on turbulence – again good news.
The initial campaigns of the Wendelstein 7-X stellarator exceeded expectations. The new systems engineering approach adopted in the predesign phase for the first demonstrational fusion power plant DEMO is a major step forward and has given the fusion community many new insights. All of these efforts and successes would not have been possible without the dedicated staff of EUROfusion and its beneficiaries.

We are now in the process of updating the fusion roadmap. The revision will be an evolution of the old one but with even more coherence between the missions. Important is the enhanced consistency between ITER and DEMO activities: In 2017, EUROfusion, Fusion for Energy (F4E) and several research institutes undertook a major effort to align the European ITER Test Blanket Module (TBM) and the DEMO Breeder Blanket (BB) programmes. This has led to much stronger synergies between F4E and the EUROfusion activities, a direct outcome of our well organised fusion programme.

Apart from the above alignment of the TBM and BB programmes, we are also collaborating closely with F4E, for instance, in the Broader Approach (Japanese Torus 60 Super Advanced, DEMO, the International Fusion Materials Irradiation Facility and various ITER-related topics). Additionally, in 2017, F4E has joined EUROfusion in EIROforum. F4E is now a member of the consortium which comprises the eight largest European research institutes. Indeed, I am pleased to announce that this edition features an interview with F4E Director Johannes Schwemmer on the occasion of the celebration of the 10th anniversary of the organisation.

Realising fusion electricity is by far one of the biggest challenges on the path of mankind. We will best be able to reach the final goal if we all cooperate. My wish for 2018 is that we continue the good work and achieve many positive results.

EUROfusion Programme Manager
