Description

Decay heat removal from BN-1200 to atmospheric air is performed using passive DHRS. Several innovative solutions are applied during the DHRS development: - hydraulic connection of the decay heat exchanger (DHX) with reactor high pressure plenum, installation of check valve at DHX outlet; - application of slide valve of air heat exchanger with passive elements; - natural circulation in all DHRS circuits. Set of experimental research is performed at facilities with water and sodium: - hydraulic testing of several options of DHX check valve are performed using scaled-down models; - main characteristics of the check valve are determined using full-scale model; - in the closed position of check valve diffusion like process was investigated (long-term testing); - experimental studies of thermohydraulic characteristics are performed using scaled-down reactor model with one DHRS loop. Integrated computational validation of DHRS effectiveness is performed using new generation code SOCRAT-BN.
