The MBIR is a multi-loop research reactor capable of testing lead, lead-bismuth and gas coolants, and run on MOX fuel. MBIR intends to replace the old BOR-60 experimental fast reactor that started operations at RIAR'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]
