The MBIR (Russian: Многоцелевой Быстрый Исследовательский Реактор, romanized: Mnogotselevoy Bystryy Issledovatel'skiy Reaktor, lit. 'Multipurpose Fast Research Reactor') 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]
