Bochvar institute (analysis facility of TVEL Fuel Company of Rosatom) has developed gasoline rod design based mostly on nitride uranium-plutonium gasoline (MNUP-fuel) for the BREST-OD-300 quick neutron reactor. This gasoline rod challenge can be utilized for industrial manufacturing of nitride gasoline to be launched as a part of the Pilot Demonstration Energy Complex, which is beneath building in Seversk, Tomsk area.
At the identical time, Rosatom’s Nuclear Fuel Division continues growth of the second-generation gasoline rods for the BREST-OD-300 with the next burnout stage, which can be used when MNUP fabrication will shift to the re-fabrication stage (which means that irradiated gasoline of the primary load after irradiation and reprocessing can be used for recent gasoline fabrication).
“Pilot gasoline assemblies with nitride gasoline have been irradiated within the BN-600 reactor on the Beloyarsk NPP since 2014. Though the adequate validated gasoline burnout for the BREST preliminary load is 6%, in the middle of the testing we’ve already achieved the 9% stage. These outcomes give us the grounds for the gasoline rod endurance exams with 9-10% burnout”, stated Mikhail Skupov, Deputy Director General of the Bochvar Institute.
“The analysis outcomes associated to nitride gasoline for the BREST reactor will considerably speed up gasoline growth for the nitride core model of the following era BN-1200M quick reactor. In 2022, experimental gasoline assemblies with gasoline rods of BN-1200M sort are scheduled to be loaded within the BN-600 for endurance exams”, stated Alexander Ugryumov, Vice President for Research, Development and Quality at TVEL JSC.
The Siberian Chemical Combine (an enterprise of ROSATOM’s TVEL Fuel Company) continues the development of the MNUP gasoline fabrication/re-fabrication module as a part of the Pilot Demonstration Energy Complex. On 10 February 10 2021, the Federal Service for Environmental, Technological and Nuclear Supervision (Rostechnadzor) issued a license to for building of BREST-OD-300, the world’s first energy unit with a lead-cooled quick neutron reactor.
