基于应急运行的核动力装置一回路小破口失水事故

针对船用核动力装置运行的特殊性,指出基于应急运行的事故研究对有效地维持机动性有重要意义.选用不可隔离的小破口失水事故进行分析计算,重点研究破口大小和不同处置对反应堆运行时间的影响.结果表明,若破口尺寸在某一范围内时,可以保证反应堆在一定时间内实现应急运行,并且在一定条件下通过降功率可以延长运行时间.

On small-break loss-of-coolant accident in marine nuclear power plant based on emergency operation

Aiming at the particularity of marine nuclear reactor,it was pointed that the study of emergency operation during accidents was of great importance to maintain its maneuverability effectively.SBLOCA that cannot be segregated was chosen to analyze,and the influences of size and positions on the operating time of reactor were mainly studied.The results show that if the breaking size is in a certain range,the emergency operation can be achieved for a period of time,and operating time could be prolonged with a ...
