Abstract

Abstract

In this study, based on the phenomena and characteristics of LOCA for the small modular PWRs, the mechanism for the occurrence of Peak Cladding Temperature（PCT） was analyzed, and the effects of accumulator（ACC） design on PCT and system depressurization were studied. It is shown that the accumulator injection may lead to more penalizing results for special medium size LOCA, and this result could be considered in the system design of small modular PWR.
