MSIV closure ATWS mitigation of SBWR with the standby liquid control system

Conference ·
OSTI ID:10180191

An Anticipated Transient Without Scram (ATWS) initiated by inadvertent closure of the Main Stream Isolation Valve has been analyzed using the RAMONA-4B code of Brookhaven Laboratory (1994). The Simplified Boiling Water Reactor (SBWR) operating in natural circulation is designed with many passive safety features. This analysis demonstrates the effectiveness of the heat-removal system during an ATWS, followed by shut down of the reactor through injection of boron into the reactor core from the Standby Liquid Control System (SLCS).
