摘要
一、前言根据《中华人民共和国民用核设施监督管理条例》及其实施细则的规定,国家核安全局决定对清华5 MW低温核供热站试车、反应堆装料、临界、低功率试验和功率试验进行监督检查,并委托北京核安全审评中心组织检查组实施检查。我们参加了核供热站整个调试启动的监督检查工作。反应堆物理启动监督检查是其中一个检查项目。
Through the inspection on physical start-up of reactor, it is identified thatthe.data of critical extrapolation and transition and the implementation of safetylimit are correct. The results of inspection show that the physical start-up for 5MW NDHR is successful. The steady doubling time after critical transition is 237seconds, it is within the acceptance criteria 30--300 seconds. The nuclear instru-mentation systems which are.used for normal operation have response to the neu-tron.flux at this power level. The reactor power is below protection set-point.
