On 28 April, the ITER Organization signed a contract with the European consortium GNMS for the procurement of approximately 10 km of vacuum pipework, ranging in diameter from DN 25 to DN 250.

The ITER vacuum system will be one of the largest in the world. Vacuum pumping is required prior to starting the fusion reaction to eliminate all sources of organic molecules and to create low density—about one million times lower than the density of air. The network of pipework will form one of the most extensive distributed systems in ITER, alongside cryogenic and water cooling systems.

The contract signature marks a significant step forward for the ITER vacuum system.

US Department of Energy (DOE) Secretary Ernest Moniz dedicated the most powerful spherical torus fusion facility in the world on 20 May 2016. The $94-million upgrade to the National Spherical Torus Experiment (NSTX-U), funded by the DOE Office of Science, is a spherical tokamak fusion device that explores the creation of high-performance plasmas at 100-million degree temperatures.

NSTX-U at the Princeton Plasma Physics Laboratory (PPPL) will allow researchers around the world to explore fusion reactions [...] "The vastly expanded capabilities of this spherical tokamak will enable us to explore new physics regimes and tackle the major engineering problems for fusion energy," Moniz said.

NSTX-U draws on a 65-year-old legacy of fusion energy research at Princeton University's Plasma Physics Laboratory where, in the 1950s, physicist Lyman Spitzer created a machine he called a stellarator to produce energy the same way as the Sun. Experimental stellarators and tokamaks, the two most prominent fusion reactor designs, now dot the globe.

"This is exciting new territory, and we're thrilled to embark on the next frontier of fusion research. This device could transform the world by showing us the way to a pilot plant design for the generation of power from fusion energy for use by all," said Stewart Prager, director, Princeton Plasma Physics Laboratory.

A new energy technology "distillate" has been published by Princeton University's Andlinger Center for Energy and the Environment on magnetic confinement fusion, a technology with "enormous promise" as a global energy source, according to the authors.

The paper presents some of the basic science relevant to fusion energy and the central technical challenges before addressing the economic prospects for commercial fusion, the differences between fusion and fission, and the politics and progress in the global effort to develop nuclear fusion.

Andlinger Center distillates aim to provide succinct yet substantive information to a non-specialist audience on emerging topics in energy and the environment that combine technological, economic, and policy considerations. This is the third in the series so far.

Are you a university graduate who wants to gain international professional experience and contribute to the work of the European Domestic Agency for ITER? Or who is curious about ITER and simply wants to be part of one of the most ambitious energy projects in the world today? The European Domestic Agency for ITER is looking for graduates in engineering, physics, law, human resources, finance and communication for four to nine months beginning 1 October 2016.

The traineeship program is open to university graduates who are nationals of one of the Member States of the European Union or Switzerland, who have at least a three-year university degree obtained within the last three years, and a very good knowledge of English. Traineeships are offered in Barcelona (Spain), Garching (Germany) and at the ITER site in France.

The deadline to apply is 31 May 2016. Please find all information .
