Abstract

Abstract

The secondary side passive residual heat removal (PRHRS) of Russian SVBR-100 lead-bismuth reactor was chosen as the research object, and the RELAP5/MOD4.0 code was used to model and evaluate the heat removal capacity and parameter sensitivity of PRHRS under station blackout (SBO) accident. The results show that the key parameter of the peak cladding temperature is 816.35 K during the whole SBO accident, which is within the safety limit. PRHRS can timely remove the residual heat. By increasing the heat exchange area of the built-in condensing heat exchanger in PRHRS water tank, the residual heat removal capacity of PRHRS can be enhanced. The safety analysis model and evaluation method for secondary side PRHRS established in this study can provide technical reference for the design and application of PRHRS of lead-cooled reactor in China.
