摘要
Abstract
By simulation analysis with the integral severe accident analysis code MELCOR1.8.5, the applicability of the Westinghouse Owners Group Core Damage Assessment Guidance (CDAG) to estimate the status and extent of the core damage in the early phase of the accident for a typical Chinese 1 000 MWe NPP was investigated. The preliminary analysis results show that CDAG can reasonably evaluate the core damage status and extent for the 1 000 MWe NPP in a loss of coolant accident (LOCA) without mitigation measures. The insights gained from the present study are of significant values for further studing and validating the comprehensive assessment capability and applicability of the CDAG, and for advancing the establishment of the severe accident management guidelines (SAMGs) of existing plants in China.关键词
