Critical Test Bench

The critical test bench is a low power thermal neutron physical reactor that includes light water moderator and reflector (water or beryllium). It is meant for studies of neutron-physical characteristics of WWR type water-water reactor cores and other reactor core elements, for experiments to validate reactor facility safety, as well as for simulation of conditions of loop channel and different in-pile device tests. The diameters of central experimental channels are 65, 96, 140 and 380 mm, diameters of peripheral channels are 65, 96 and 140 mm, thermal neutron flux density is 5×10⁸ n/cm²·s.
