[1F17] Designing melting core cooling system for existing ABWR

*Akira Kirihara1, Shinichi Morooka1 (1. WASEDA University)

Keywords:melting core, ABWR, natural circulation, critical heat flux

This study was performed to examine melting core cooling system for existing ABWR using natural circulation. The evaluated critical heat flux margin of this cooling system revealed that this system secure safety.
