The MBIR is a multi-loop research reactor capable of testing lead, lead-bismuth and gas coolants, and run onMOX fuel. MBIR intends to replace the oldBOR-60 experimentalfast reactor that started operations atRIAR's site in 1969. It will have a design life of 50 years.[3]
Construction has started in 2015.[4]
MBIR control assembly was installed in 2019.[5]
Reactor vessel was installed in 2023.[6]
Pilot fuel elements were produced in 2024. The MBIR is scheduled to begin operation in 2027.[3]
Estimated commissioning date is 2028.[2]
