In the past experimentation round, Wendelstein 7-X achieved the stellarators’ world record for the fusion product as a result of reaching higher temperatures and densities of the plasma as well as longer pulses. Wendelstein 7-X attained a fusion product of 6·1026 degrees x second per cubic metre which is the world’s stellarator record and gives first confirmation that the optimisation carried out for its design has been successful.

The Summit supercomputer hosted at the US Department of Energy’s Oak Ridge National Laboratory (ORNL) has been announced as the fastest supercomputer in the world, according to the TOP500 List.

The IBM Summit system reached a speed of 122.3 petaflops on the High-Performance Linpack benchmark test—the software used to evaluate and rank supercomputers on the TOP500 list. At its theoretical peak, Summit is capable of 200 petaflops (double precision), or 200 quadrillion calculations per second, about eight times more performance than its predecessor Titan.

Spain and Croatia push the candidature of Granada for IFMIF-DONES

Science and Research Ministers from Spain and Croatia, Pedro Duque and Blazenka Divjak, have signed a cooperation agreement pushing the candidature of Granada (Spain) for IFMIF-DONES facility.

Spain and Croatia presented initially independent candidatures but they joined their efforts in order to present a common European candidature. IFMIF-DONES aims to study the extreme conditions of fusion materials under energy production and particularly research on irradiation for DEMO operation. The estimated budget for the construction is between 400 and 600 million euros and the construction will take 10 years and it will be operating at least 20 years.

On the modelling of neutron transport in a fusion reactor

In the process of fusion energy production based hydrogen heavy isotopes deuterium and tritium as fuel, high-energy neutrons are released. These neutrons have many roles in a fusion reactor.

On one side, neutrons from the fusion reactions taking place in the fuel inside the reactor vacuum vessel generate the heat that, in a fusion plant, will initiate the electricity-producing process. Moreover, neutron interaction with lithium inside the machine will produce tritium.

Divertor Tokamak Test Facility to be built in Italy

The Divertor Tokamak Test (DTT) Facility will be built in Frascati, Rome, Italy, as has been announced by Italian National Agency for New Technologies, Energy and Sustainable Economic Development (ENEA). It will be part of the International Center of Excellence for nuclear fusion research and will have a cost of 500 million euros.

This experimental machine will provide scientific and technological answers to some particularly complex problems of the fusion process (such as the management of very high temperatures) and stands as a “link” between ITER and DEMO international projects. Therefore DTT should operate integrating various aspects, with significant power loads, flexible divertors, plasma edge and bulk conditions approaching as much as possible those planned for DEMO, at least in terms of dimensionless parameters.

Code Development at Integrated Fusion Modelling Code Camp at Poznan

Poznan Supercomputing and Networking Centre (PSNC), Poland.

From the 3rd to the 13th of April, our fusion group has participated in the Code Camp of the EUROfusion “Code Development for Integrated Modelling” (WPCD) Work Package at Poznan Supercomputing and Networking Centre (PSNC), Poznan, Poland.

WPCD develops generic and flexible sophisticated workflows for physics applications, aiming at providing a validated modular suite for the simulation of complete plasma discharges of any existing and future tokamak, including JET, JT-60SA, ITER and DEMO.
