The Russian MBIR is a 150 MWt, sodium-cooled fast reactor and will have a design life of up to 50 years. It will be a multi-loop research reactor capable of testing lead, lead-bismuth and gas coolants, and running on MOX (mixed uranium and plutonium oxide) fuel. NIIAR intends to set up on-site closed fuel cycle facilities for the MBIR, using pyrochemical reprocessing it has developed at pilot scale.
AEM-Technology started the manufacture of the reactor pressure vessel for MBIR in March last year and has said that construction of the demonstration reactor should be completed by 2020.
Russia is building a fast MBIR reactor with a capacity of about 150 thermal megawatts. It wil be the most powerful research reactor in the world.
The project is expected to cost 16.4 billion rubles ($454 million).
