IBR-2 Pulsed Reactor

The IBR-2 reactor hall

The IBR-2 reactor with its unique technical approach produces one of the most intense pulse neutron flux at the moderator surface among the world's reactors: ~1016 n/cm2/s, with a power of 1850 MW in pulse.

Nevertheless, the reactor is "ecologically friendly": it consumes very little electrical energy comparing to other research reactors, has practically no emissions, uses a very little amount of fuel (less than 20 l) that is changed once in 15-20 years.

The reactor operates continuously for a 12 day cycle followed by a shutdown to prepare for the next experiments. In addition, there is a longer shutdown to carry out necessary maintenance work during the summer time. Normally there are about 9 cycles a year.
