百万千瓦级核电厂地震风险评价和见解

摘要

The seismic risk assessment was done for a specific mega‐kilowatt class nucle‐ar power plant .Site specific seismic hazard curves and seismic fragility curves for equip‐ment of the plant were developed . The seismic probabilistic risk assessment (PRA ) model was done and the quantification evaluation was completed . The seismic risk results and insights for the plant were presented finally .The results show that the seis‐mic risk of the plant is relatively low and the contribution of the interval between 0.3 g and 0.6 g is the most significant .%针对特定百万千瓦级压水堆核电厂开展地震概率风险评价，开发了电厂特定的地震危险性曲线和设备的地震易损度曲线，建立地震概率风险评价模型并完成定量化，给出地震风险结果和见解。结果表明，该特定电厂地震风险水平较低，在0.3g～0.6g地震动水平区间内地震风险贡献最为突出。
