BREST (reactor)


The BREST reactor is a Russian concept of lead-cooled fast reactor aiming to the standards of a generation IV reactor. Two designs are planned, the BREST-300 and the BREST-1200. Main characteristics of the BREST reactor are passive safety and a closed fuel cycle.
The reactor uses nitride uranium-plutonium fuel, is a breeder reactor and can burn long-term radioactive waste. Lead is chosen as a coolant for being high-boiling, radiation-resistant, low-activated and at atmospheric pressure.

BREST-300

The construction of the BREST-300-OD in Seversk was approved in August 2016.. The preparatory construction work commenced in May 2020.
The first BREST-300 will be a demonstration unit, as forerunner to the BREST-1200.
