Abstract

Based on a revised version of Relap5, a model of the mixed spectrum SCWR (SCWR-M) system is established. In order to optimize the SCWR-M system design, the Loss of Flow Transient (LOFT) is selected as a significant transient for the SCWR-M system safety analysis. To analysis the transient behavior of SCWR-M during LOFT, some important parameters, e.g. reactor coolant pump (RCP) coast-down time, Reactor Pressure Vessel (RPV) upper water volume and safety injection flow are chosen as the main parameters. The results achieved so far indicated that the SCWR-M system design is feasible and promising.
