利用 MELCOR 程序建立了船用堆计算模型，通过模拟船用堆全船断电事故进程，分析了全船断电事故的热工水力及堆芯失效过程。建立了稳压器波动管蠕变失效模型，实现了 MELCOR 程序对稳压器波动管蠕变失效问题的计算分析。对波动管破口尺寸进行了敏感性分析，结果表明：破口尺寸越大，事故进程越快。全船断电事故舱底的熔穿及稳压器波动管的失效，给船用堆的抗沉性及船内人员健康带来潜在的危害。

A computation model of the marine reactor is established by use of the MELCOR program . The simulation of the process of blackout accident resulting from the marine reactor helps analyze the cause of the thermodynamic and reactor core failure leading to the ship electricity cutoff .Therefore , the creep failure model of pressurizer surge tube is established to make a computation and analysis of the problem of creep failure in the pressurizer surge tube .The sensibility analysis of the breaking size of the surge tube proves that the bigger the breaking ,the faster the accident progresses .It will bring potential hazards to the sinking resistant capability of the marine reactor and to the health of the ship ′s crew because of the melt penetration of the cabin bottom and the failure of pressurizer surge tube in the ship blackout accident .
