| 摘 要： | 通常认为堆外探测器读数与反应堆总功率之间存在正比关系,这其实很不合理,在实际运行过程中会出现很大的偏差。堆芯功率分布和堆外探测器读数的映射关系可以通过空间响应函数来更好地表达。论文介绍了空间响应函数的计算方法,压水堆的堆外探测器空间响应函数的特点、影响因素,以及其在反应堆功率重构中作用。

| Abstract: | It is normally assurned that the ex-core detector readings are proportional to reactor total power,but actually it is not true for real reactor.The relationship between in-core power distribution and ex-core detector readings can be modeled better thorough the detector space response function.The paper described the method to calculate the detector space response function,the characteristics of the space response function in pressurized water reactor,and the application of detector space response function in the in-core power distribution reconstruction. |
