MBIR

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.

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

History

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
