COTELS Project Angara test bench

The project objective is to experimentally study the processes typical of the final phase in water-cooled reactor accident involving loss of coolant (LOCA type accident), in particular, the processes related to interaction between corium melt and water/concrete. The experiments are conducted by the NNC RK in cooperation with the NUPEC Japanese Corporation and will be continued within the planned IVR-AM project. The IVR-AM goal is to study the interaction process between corium and lower head of reactor power vessel under conditions simulating the phase of reactor severe accident inside its vessel and at simulating residual heat release in the fuel.

To conduct the mentioned experiments SLAVA, LAVA, LAVA-M and LAVA -B experimental facilities were created on the basis of the equipment available at the NNC RK.
