ºÚÁÏÉçapp

Thirty-seven seconds might seem like a very short duration—but not for a plasma, and even less for a plasma produced by a machine that is just commencing operations.

The 37-second plasma that WEST obtained on 31 October exceeds by 7 seconds the first of five milestones ("Key Project Indicators") that were assigned to the machine on its way to final commissioning.

The good news did not come alone—the final ºÚÁÏÉçapp-like, actively-cooled full tungsten divertor has just been ordered. It will replace the present non-actively cooled divertor made of tungsten-covered graphite blocks and only a few actively cooled test plasma-facing units.

When this new divertor is installed, WEST will be able to produce ºÚÁÏÉçapp-relevant plasmas of up to 1,000 seconds.

At the Troitsk Institute for Innovative and Fusion Research (Moscow region), specialists have established a unique remote control panel that enables participation on leading fusion devices around the world.

Based on the facility's lab complex for neutron and spectroscopy diagnostics, the panel will facilitate the creation and calibration of diagnostic systems for ºÚÁÏÉçapp under Russian procurement scope.

The first cooperation line has been established with Europe's JET tokamak, based in Culham, UK.  

The UK government has pledged to provide an additional £20m in 2019-20 to the UK Atomic Energy Agency (UKAEA), the public body responsible for research into nuclear fusion and the management of the country's largest fusion research laboratory, the Culham Centre for Fusion Energy (CCFE).

"We think fusion has a big role to play," said UKAEA CEO Professor Ian Chapman. "The fuels are abundant around the globe, it doesn't release greenhouse gases and it doesn't produce long-lived radioactive waste like the nuclear fission power we have today."

The 2018 Budget reaffirms the government's commitment to nuclear energy following an absence of new investments into the sector in the 2017 Budget.

According to the World Nuclear Association, nuclear power accounted for 21% of UK electricity in September this year, however "almost half" of the country's 15 reactors are expected to be decommissioned by 2025.
