Abstract

The present work focuses on a simulation of increase of coolant inventory due to malfunction of chemical and volume control system (CVCS) in advance passive pressure water reactor 1000 (AP1000) operating at a 102% nominal power before transient start-up. The objective is to verify if this transient may induce any over pressure in the reactor coolant pressure boundary due to inadequate residual heat removal. RELAP5 system code was used to simulate the transient and the simulation result was compared with the simulation result by LOFTRAN code. The RELAP5 simulation result is well comparable with the simulation result by LOFTRAN and this transient does not endanger the AP1000 pressure boundary system.
