In order to master what's commonly refered to as "the energy transition," a diversity of energy sources need to be matched up in the energy system of the future ¡ª decentralized and centralized, weather-dependent and continuously operable units.

The technological and economic interactions of all system components (generation, storage, load and transport facilities) and their intelligent networking are being tackled by the Energy System Integration project, which the Helmholtz Association is funding with five million euros in the next three years in the context of their Initiative and Networking Fund. The partners involved, including Max Planck Institute for Plasma Physics (IPP) at Garching und Greifswald, are making further contributions.

The aim of the research project is to model the architecture for an environmentally compatible, efficient and stable energy system of the future.

Expected as new primary energy source in the second half of the century are fusion power plants, environmentally and climatically friendly facilities supplying about one gigawatt of electric power. The contribution of IPP will therefore be to work out the physical and technical properties of these devices ¡ª of either the tokamak or stellarator type.

At the Culham Centre for Fusion Energy in the UK, the central magnet of the new MAST upgrade tokamak was positioned in early March, bringing the project one step closer to the finishing line.

When completed, the MAST upgrade will mark a step-up in performance from the original device, with an increase in magnetic field from 0.52 tesla to 0.78 tesla and in pulse length from 0.5 seconds to 5 seconds. The centre column, completely re-manufactured, is part of the magnetic coil system of the device with the role of inducing current to begin to heat the plasma.

Commissioning should begin this year.

For five years, it has been a resource for the plasma physics community. The Helios supercomputer has performed complex calculations for plasma physics and fusion technology, allowing users to draw comparisons between current fusion experiments and run predictive simulations for future devices like ºÚÁÏÉçapp.  

Helios has been in operation at the International Fusion Energy Research Centre (IFERC), hosted by the Japanese Atomic Energy Authority (JAEA) since late 2011. IFERC is one of the sub-projects of the  agreement signed between Europe and Japan for advanced fusion R&D in complement to ºÚÁÏÉçapp.

After a very successful operational campaign, Helios was shut down earlier this year.

The European tokamak JET is currently in an engineering shutdown phase. But shutdown doesn't mean inactivity¡ªscientists are currently reviewing the 2015-2016 experimental campaign and preparing for the next scientific program, which will include tritium-tritium operation followed by full fusion power experiments using deuterium and tritium in 2019.

The JET remote handling team has taken advantage of shutdown to carry out a photographic survey of the vacuum vessel to inspect the condition of the wall, and to calibrate the detector that measures neutrons using the remote handling system¡ªa system allowing operators to undertake a wide range of tasks including welding, cutting, bolting, handling and inspection through a special manipulator that acts almost as the extension of an arm.

Scientists from the Max Planck Institute for Intelligent Systems, the Max Planck Institute for Solid State Research, the University of Leipzig, Jacobs University Bremen, the University of Augsburg, and the US Department of Energy's Oak Ridge National Laboratory (ORNL) are working collaboratively on a new technique for filtering the fusion fuel deuterium out of the natural isotopic mixture of hydrogen.

Deuterium is obtained from heavy water, which occurs in natural water at a concentration of just 15 parts per thousand. The heavy water is first isolated by a combination of chemical and physical methods, such as distillation, to obtain deuterium gas. The whole process is so intricate and energy-intensive that a gram of deuterium with a purity of 99.8 percent costs around $100, making hydrogen's heavy brother around three times more precious than gold, although deuterium is more than 300 times more abundant in the oceans and Earth's crust than gold.

A metal-organic framework compound presented by the group could make the process easier and less energy-intensive.

The lectures¡ªheld in English¡ªare designed for physics and engineering students who have passed their bachelor (undergraduate) courses or Masters students who have not yet decided their PhD topic.   The next summer school will take place from 11 to 15 September 2017 at the Max Planck Institute for Plasma Physics (IPP) in Garching, Germany. Follow  for more information.

Some 4,500 components, large and small, will be shipped to ºÚÁÏÉçapp for integration into the ºÚÁÏÉçapp cryoplant, which is under construction now on the ºÚÁÏÉçapp platform.

Two of the largest were delivered in November 2016 by the European Domestic Agency: 35-metre quench tanks that will store gaseous helium in the case of a magnet quench.

The tanks are formed from an inner stainless steel container that will hold the gas and an outer carbon steel shell that will insulate the inner vessel and keep the temperatures low.

Manufacturered by Air Liquide subcontractor Chart Ferox (Czech Republic) according to ºÚÁÏÉçapp and European Domestic Agency requirements, the tanks travelled at night in a long convoy along the ºÚÁÏÉçapp Itinerary from the Mediterranean port of Fos-sur-Mer to ºÚÁÏÉçapp.

A physicist at the Culham Centre for Fusion Energy (CCFE) is developing a code to calibrate camera views of fusion experiments.  

For the past two years, Scott Silburn has been leading the development of Calcam, a program for calibrating camera viewing geometry on fusion devices. The program allows the user to match up features seen in the camera images with those on a computer-aided design model from the drawing office at Culham. From this, the position, orientation, and lens properties of a camera system can be determined. This information can then be used to calculate exactly where the camera's lines-of-sight pass through the plasma, and also which locations on in-vessel components correspond to which positions in the image.

An example application of the code is improved positional calibration for JET's high-resolution divertor infrared cameras, which measure the heat loads at the strike points where the plasma interacts with the divertor tiles. The improved information has been used to improve the accuracy of some of the signals from the cameras, and makes it easier to compare the camera data against other diagnostic signals.

An agreable off-shoot of the technique is that it produces interesting images, as seen in the image above (photo credit: CCFE).

On 30 January, six large steel elements of the ºÚÁÏÉçapp cryostat left the port of Hazira, India for their one-month voyage to ºÚÁÏÉçapp.

These are the first segments of the cryostat lower cylinder (tier 1). On site at ºÚÁÏÉçapp, assembly activities (welding, testing) for the cryostat base have been underway since September 2016

 

A lot has happened on the construction platform since the ºÚÁÏÉçapp 360¡ã virtual tour was released to the website last year with an October data set.

The first ground-level walls of the Tokamak Complex are now visible from afar, the circular bioshield dominates in the centre, and two new buildings¡ªone for radiofrequency heating and the other for cryogenics¡ªare now completely framed out. Elsewhere on site, excavation and early foundation works are underway and the first activities to energize the 400 kV electrical switchyard have been carried out.

The best way to catch up on recent progress is to open the January 2017 update of the 360¡ã virtual tour.

In a recent statement to parliament, the UK government confirmed that¡ªas part of withdrawal from the European Union¡ªthe UK would also withdraw from the Euratom Treaty.

On 27 January EUROfusion, which manages European fusion research activities (including the exploitation of the JET tokamak) on behalf of Euratom, issued the following statement: 

Although the withdrawal from Euratom brings in uncertainty to the future of the Joint European Torus (JET), EUROfusion's flagship experiment located at the Culham Center of Fusion Energy (CCFE) in Oxfordshire, the UK government has indicated strong interest in continuing collaboration in nuclear research. "The UK is a world leader in nuclear research and development and there is no intention to reduce our ambition in this important area. The UK fully recognises the importance of international collaboration in nuclear research and development and we will ensure this continues by seeking alternative arrangements," the government said in the statement.

[...] Researchers, engineers and technicians working at JET come from all over Europe, and currently, JET operations receive funding of €69 million, 87.5 percent of which is provided by the European Commission and 12.5 percent by the UK. It is the only existing fusion device capable of operating with the deuterium-tritium fuel, which will be the fusion fuel of the future. And, experiments carried out at JET are important foundations to the fusion experiment ºÚÁÏÉçapp, which is currently being built in Cadarache, France. "Naturally, the European fusion community is extremely interested to see a continuation of the JET programme," says Prof. Donn¨¦, EUROfusion program manager.

Aix-Marseille University and the ºÚÁÏÉçapp are pleased to announce the 9th ºÚÁÏÉçapp International School which will be held in Aix-en-Provence, France, from 20-24 March 2017.

This school, held annually either near ºÚÁÏÉçapp or in one of the ºÚÁÏÉçapp Members, aims at preparing young researchers to tackle the challenges of magnetic fusion devices, and spreading the global knowledge required for a timely and competent exploitation of the ºÚÁÏÉçapp physics potential.

This year, the summer school will cover the physics of disruptions and control¡ªone of the key issues for the ºÚÁÏÉçapp reactor and burning plasmas in general. Lectures and specialized seminars will cover current developments in theory and experiments, but are also intended to give the basics of the field. Poster sessions allowing participants to show their work are planned. The 2017 ºÚÁÏÉçapp school will be a good opportunity for reviewing the recent progresses in this field and promoting the interaction between different branches of plasma physics, computational physics and applied mathematics.

The course is open to PhD students and postdocs aiming to work in the field of magnetically confined fusion, as well as Master students in physics or engineering.

Registration ends on 7 March 2017. For more information, please visit the .

Editor's note: The first ºÚÁÏÉçapp school was organized in July 2007 in Aix-en-Provence, France, and was focused on turbulent transport in fusion plasmas. Five different editions have followed, focused on different subjects: in 2008 in Fukuoka, Japan (magnetic confinement); in 2009 in Aix-en-Provence, France (plasma-surface interaction); in 2010 in Austin, Texas (Magneto-Hydro-Dynamics); in 2011 in Aix-en-Provence (energetic particles); in 2012 in Ahmedabad, India (radio-frequency heating), in 2014 in Aix-en-Provence (high performance computing in fusion science); and in 2016 in Hefei, China (transport and pedestal physics in tokamaks).

Could high-entropy alloys¡ªa combination of different metals in roughly equal concentration¡ªturn out to be THE material for fusion reactors? That's the question materials physicists from the University of Helsinki (Finland) and the Oak Ridge National Laboratory (US) are investigating.

The concept behind the creation of these alloys is ten years old and was first proposed by metallurgists. But based on work done at Oak Ridge, where these new hybrid metals were being tested under the influence of radiation, researchers in Finland began running experiments and simulations using different mixtures with nickel.

High-entropy alloys appear to be much more resistant to radiation than pure alloys. To date, the labs at Oak Ridge and the University of Helsinki have just combined two, three or four elements, whereas millions of possible combinations exist.

Specialists from The Welding Institute (TWI) in the United Kingdom visited ºÚÁÏÉçapp on 18 January to deliver a workshop to over 70 attendees from across the organization.

Overviews were given on different welding, joining and inspection techniques as well as the benefits and services available to ºÚÁÏÉçapp as corporate members of the TWI. Details of previous case studies carried out for both the ºÚÁÏÉçapp and the European Domestic Agency were provided to demonstrate the large portfolio of services that can be called on.

During the open discussions there was particular interest from a number of ºÚÁÏÉçapp divisions in the potential use of ultrasonic inspection for both thin wall pipes and thick-section plates as an alternative to radiography; auditing of potential/in-contract suppliers; and third party manufacturing process review capabilities. Follow up meetings and initiatives on these and other subjects are anticipated to address the challenging, state of the art manufacturing processes required both at suppliers and on-site to enable the construction and assembly of ºÚÁÏÉçapp.

At the EAST tokamak in China, five Italian scientists recently joined their Chinese colleagues to participate in a week-long experiment aimed at testing a voltage-driven vertical stabilization system. The successful tests, carried out in the framework of a joint ASIPP-CREATE-ENEA collaboration, were a key step on the way to MIMO (multiple input, multiple output) control of advanced tokamak configurations, capable of decoupling shape control from vertical stabilization.

The new vertical stabilization system implemented and tested on EAST is identical to the one proposed for ºÚÁÏÉçapp, and these first tests show that it is compatible with the installation a new ºÚÁÏÉçapp-like multivariable shape controller for advanced configurations.

In 2012 the ºÚÁÏÉçapp retained the European company DAHER to provide global transport, logistic and insurance services for the transport of components from supplier factories to the ºÚÁÏÉçapp site.

Since that date, DAHER has worked with all ºÚÁÏÉçapp Members on their transport needs, including the transport of exceptionally sized loads. The company manages all ºÚÁÏÉçapp logistics operations from a control room established in Marignane, France, close to the international airport that services the Marseille region.

In November 2016, the ºÚÁÏÉçapp strengthened its ongoing relationship with DAHER with the signature of a new framework contract for the establishment and management of a central distribution centre located at the arrival port for all components shipped by sea (Fos-sur-Mer, France).

A warehouse space of 12,000 m2 has been fully refitted for ºÚÁÏÉçapp component storage. The central distribution centre will allow DAHER to match the rhythm of component deliveries to ºÚÁÏÉçapp's assembly needs.

Precise conditions are necessary to achieve fusion reactions inside of a high-temperature plasma. In addition to raising the temperature and the density in the core region of the plasma, which is confined by strong magnetic field, it is also necessary to control the edge region to prevent particles from moving in the direction of the vessel wall. 

A precise understanding of this edge region of the plasma¡ªand accurate predictions of its behaviour¡ªis one of the important topics of fusion research around the world.

At the National Institute of Fusion Science (NIFS) in Japan, two researchers have succeeded in running a micro-level simulation of a plasma "blob" in the edge region by using their institute's Plasma Simulator supercomputer.

By marrying the supercomputer's computational capacity with a newly developed calculation program, they were able to calculate the movement of one billion particles. Their research results advance the understanding of the behaviour of the plasma edge and improve prediction accuracy.
