On February 10, 2021, the Siberian Chemical Combine (SCC) received a license for the construction of a lead-cooled fast neutron rector BREST-OD-300 from the Russian nuclear regulator, Rostechnadzor.

According to Alexey Aleshin, the head of Rostechnadzor, while Rostechnadzor and expert organizations were reviewing the SCC license application, stakeholders developed and approved a set of safety regulations specific to BREST-OD-300 reactor. This includes two Federal Norms and Rules approved by Rostechnadzor that establish mandatory safety requirements to the reactor and sixteen Rosatom standards providing guidance on implementing Rostechnadzor requirements and taking into account the specifics of the reactor.

BREST-OD-300 reactor is a key part of a pilot closed fuel cycle facility (also known as the Pilot-Demonstration Energy Complex) constructed at the SCC site within the framework of the "Proryv" (Breakthrough) Project. The pilot closed fuel cycle facility also includes spent fuel reprocessing module and fuel fabrication and refabrication module.

The SCC started the installation of equipment at the fuel fabrication refabrication module in August 2020. The installation will take about a year and a half. The SCC also completed the design of the spent fuel reprocessing module but did not start construction of the module yet.

According to the management of the "Proryv" Project, the full-scale operation of the pilot closed fuel cycle facility is expected in 2029.

Previous status reports and additional details on the development of the pilot closed fuel cycle facility are available in the July/August 2020 issue of the Russian Nuclear Security Update.
