UK nuclear trade association, the Nuclear Industry Association (NIA) has applied for a justification decision for newcleo’s lead-cooled fast reactor design, the LFR-AS-200. The application makes the case that the benefits of clean, firm, flexible power from the LFR-AS-200 would far outweigh any potential risks. NIA says these are” rigorously controlled by robust safety features, including passive safety systems, built into the design and incorporated into the operating arrangements, in line with the UK’s regulatory requirements”.

Russia’s Siberian Chemical Plant (SCC part of Rosatom fuel company TVEL) plans in April 2026 to begin testing a small-scale model of the steam generator for the planned large-scale lead-cooled fast reactor – the BR-1200. This will be an industrial, more powerful version of the experimental Brest-OD-300, under construction at SCC as part of the pilot demonstration power complex (ODEK - Opitno Demonstratsionovo Energo-Kompleksa), which is part of the Breakthrough (Proryv) project intended to demonstrate closed fuel cycle technology.

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.

Specialists at the AI Leipunsky Institute of Physics & Power Engineering (IPPE – part of Rosatom) in Obninsk have launched a physical model of the active zone of the BN-1200M fast neutron reactor unit using the complex of fast physical stands (BFS) at the institute. “This was assembled in record time – in less than two months. Typically, such tasks require about 4-5 months, said Alexander Zhukov, head of the BFS complex. “We manually collected more than 4,700 fuel rods, which made it possible to successfully complete the critical mass set and go into critical condition. This was achieved thanks to the first-class work of the entire team of the BFS critical stands.”

The BN-800 sodium-cooled fast reactor at unit 4 of Russia’s Beloyarsk NPP has registered a year of reliable and safe operation using an almost full load of uranium-plutonium mixed oxide (MOX) fuel. Russia says this proves the readiness of the closed nuclear fuel cycle technology for implementation on an industrial scale. Beloyarsk 4 is the world's first nuclear power unit to use MOX for an entire year at almost full load. The MOX fuel assemblies (FAs) were produced at the Mining & Chemical Combine (MCC) in Zheleznogorsk, (Krasnoyarsk Territory). Unlike the enriched uranium FAs traditionally used in NPPs, the raw materials for the MOX fuel pellets includes plutonium oxide obtained during the processing of used fuel from conventional VVER reactors alongside depleted uranium oxide, obtained by defluorination of depleted uranium hexafluoride (tails from enrichment production).
