【摘要】 反应堆的冷中子源装置以液氢作为慢化剂,冷中子源堆内部件的安装位置靠近反应堆堆芯。基于对冷中子源及反应堆安全性影响的考虑,本文对冷中子源堆内部件在各种运行工况(包括失效事件)的状态及事故后果进行了分析。结果表明,堆内部件的失效影响仅局限于冷中子源内部,不会对反应堆安全造成危害。更多还原

【Abstract】 A newly constructed CNS facility at a research reactor adopts liquid hydrogen as moderator.Because the CNS facility in-pile parts was installed in reflector vessel,which is very closed to reactor core,the safety of CNS facility especially the in-pile parts is very important to the reactor.This paper analyzes the status of CNS in-pile parts in various conditions(including failure) and the accident consequences.The results show that the failure of the in-pile parts is limited to the CNS facility,which has no effect on the reactor safety.更多还原
