First Commercial MOX Assemblies Loaded At Beloyarsk-4 Fast Reactor :: The Independent Global Nuclear News Agency: The first batch of commercial mixed oxide (MOX) fuel has been loaded into the BN-800 fast neutron reactor at Beloyarsk-4, a statement by Russian state-owned nuclear fuel manufacturer Tvel said.



During the plant’s first refueling outage, staff loaded 18 MOX assemblies into the reactor core – the first phase of a plan to replace all remaining uranium-based fuel at Beloyarsk-4 with MOX fuel by the end of 2021.



Tvel said another batch of 180 MOX assemblies is scheduled to be loaded into the BN-800 reactor core later this year.



In August 2019, Tvel delivered the first MOX fuel batch to Beloyarsk-4. The assemblies were manufactured by the Mining and Chemical Combine in Zheleznogorsk, Krasnoyarsk region.
