西安脉冲堆大破口失水事故分析

Analysis on Large Break Loss of Coolant Accident for Xi’an Pulsed Reactor

摘要: 分析了西安脉冲堆大破口失水事故的特点，建立了适用的数学模型，编制了计算程序。结果表明：在大破口失水事故下，部分燃料芯体最高温度将超过设计限值，但不会发生燃料元件熔毁事故。

Abstract: he characteristics of large break loss of coolant accident (LOCA) for Xi’an Pulsed Reactor were analyzed. Aiming at large break LOCA, a mathematical model was established, and the computer code was developed. The calculation results indicate that the maximum temperature of some fuel elements exceeds its design limit, but the fuel elements are not be melt in large break LOCA.
