Calculation and Analysis of Post-MSLB Operation Based on Simulation System
-
Abstract
This paper researched the behavior of main steam line break (MSLB) accident of integrated small modular reactor (SMR) with RELAP5-3KEYMASTER simulation system. Two different conditions of MSLB, by system automatic actuation without intervention after MSLB and with operator intervention according to emergency operating procedures (EOPs) are calculated and compared. Tendency and reasons for the variation of main parameters after MSLB have been analyzed. And the events sequence and operation intervention for development and verification of EOPs are given.
