为确保不超过安全极限 ,监测什么样的变量是反应堆安全保护的关键。时刻监视它离安全限值的裕量有利于克服过剩的保守性。对缺少固定在芯内的中子探测器的情况 ,提议对DNB、芯块熔化、PCI等人们关心的安全极限 ,仍直接监测芯内功率分布 ,提出对压水堆如何设置它的安全整定值的公式 ;论述了实现这设想的先决条件为 :所监测的变量必须是实测的、空间连续的、时间连续的和快速响应的 ,并介绍了为此所开拓的某些方法。
To ensure that safety limits are not exceeded, what variables are monitored is the key to reactor safety. Surveying it from the margin of safety limits at all times helps to overcome the excess conservatism. In the absence of a neutron detector fixed in the core, it is proposed that the safety margin, such as DNB, pellet melting, PCI and others, be directly monitored and the power distribution inside the core be directly monitored. It is proposed how to set its safety setting for PWR The preconditions for realizing this assumption are: The monitored variables must be measured, spatially continuous, temporally continuous, and quickly responded to, and some of the approaches developed for this purpose are introduced.
