核电厂应急柴油发电机组定期试验启动方式的探讨

摘要

分析了国内外关于核电厂EDG定期试验启动方式的相关研究以及最新的标准和规范.介绍了国外核电厂的相关改善措施及其效果,对国内核电厂在EDG定期试验中使用慢启动的方式进行了必要性论证.为EDG启动方式改进提供了两种方案,详细分析了两种方案的风险和失效概率,为核电厂的相关改进提供了重要参考.%The related investigations and the latest standards and criterions of start-up means for periodic test of EDG in nuclear power plant (NPP )were analyzed. The related amendments and its effect in overseas NPP were described. The necessity for the adoption of slow start-up means during periodic test of EDG in domestic NPP was demonstrated. Two kinds of modification methods were brought forward, theirs venture were detailed analyzed. This provided an important reference for the related modification in NPP.
