Two nuclear start-ups, Stellaria and Thorizon, each in consortium with Orano, have been selected by the French government to receive funding through the France 2030 national investment plan to develop molten salt reactors. Each consortium has been awarded a €10m ($10,8m) grant. The two projects are the result of a collaboration of several months bringing together these three companies with the aim of developing a European molten salt reactor (MSR) sector.

Russia’s Mining & chemical Combine (MCC - part of Rosatom) in Zheleznogorsk (Krasnoyarsk) has completed all R&D on a project for a molten salt research reactor (IZhSR - Issledovatelskovo Zhidko Solevovo Reaktora) MCC Director Dmitry Kolupaev told Rosatom Director General Alexey Likhachev Rosatom Alexei Likhachev during his visit to the enterprise that the key stages had been completed. A preliminary design has been developed that describes the fundamental decisions required for the physical launch of the IZhSR. This was achieved in cooperation with many other Russian organisations.

Construction of unit 5 at Russia’s Beloyarsk NPP with a BN1200 sodium-cooled fast neutron reactor will begin in 2027, according to plant director Ivan Sidorov. The BN1200 will be the world’s largest fast neutron reactor, replacing Beloyarsk 4 with a BN800 reactor, which previously held that record. Sidorov told the Beloyarsk corporate newspaper, Quick Neutron, that work at unit 5 was on schedule. "The site for the new unit has already been determined, public hearings on the placement have been held. In accordance with the programme, we are doing engineering research, we are drilling wells for them," he said.

Rosatom’s Mining & Chemical Combine (MCC) in Zheleznogorsk, Krasnoyarsk region, has manufactured the first three fuel assemblies with uranium-plutonium mixed oxide (MOX) fuel, which also contain other transuranic elements including americium-241 and neptunium-237. The assemblies, which have completed acceptance tests, will be loaded into the BN-800 fast neutron reactor at unit 4 of the Beloyarsk NPP in 2024. The fuel will undergo pilot operation (lead-test assemblies programme) during three micro-campaigns of approximately one and a half years.

Public hearings have been held in Russia’s Sverdlovsk region on justification of a licence to use nuclear materials during research to be undertaken by the BN-800 sodium-cooled fast neutron reactor at unit 4 of the Beloyarsk NPP. The materials made available for discussion included a preliminary environmental impact assessment.

At Russia’s Mining & Chemical Combine (MCC) in Zheleznogorsk (Krasnoyarsk) the decommissioning of two legacy industrial uranium-graphite reactors, AD and ADE-1, is nearing completion. Work on the third one, ADE-2, is underway, but with a difference. It will become the main exhibit of the ADE-2 museum. The ceremony, marking the decision to establish the museum took place in 2021. The AD series reactors, designed by OKBM, are water-cooled uranium-graphite thermal neutron reactors built for the production of weapons-grade plutonium. Three more (ADE-3, 4 & 5), which were subsequently built at the Siberian Chemical Combine in Seversk, are also being decommissioned.
