【摘要】 针对核电站额定运行工况下发生冷段大破口失水事故进行了分析。分析结果表明,低压安注系统在冷段注入再循环和在冷、热段同时注入再循环时能保证堆芯冷却,并防止硼酸结晶。更多还原

【Abstract】 The analysis of large break loss of coolant accident(LBLOCA) which occured at nominal power of nuclear power plant is given.The results show that the reactor core can be cooled and boron precipitation can be prevented during the cold leg recirculation or both of cold and hot leg recirculation using low head injection system(LHIS).更多还原
