摘　　要：堆芯物理试验目的是验证堆芯设计的准确性、验证换料安全分析报告的正确性。国内有些电厂物理试验项目的试验点偏少,不但造成上述验证的不充分,而且增加了后续燃料循环堆芯设计的不确定性;更不能及时发现问题,对程序模型进行改进。物理试验测量值超过设计准则或安全准则,必须经过审查和评价,获得安全监管当局许可后,才能继续运行。The purpose of reactor physics tests is to demonstrate the validity of reactor core design and refueling safety analysis report.Physics test points for some NPPs in China are fewer,which leads to insufficiency of above demonstration and increases the uncertainty of next fuel cycle design.Moreover,it will lead to that the problems can not be found in time and the physics computation model can not be improved.If the measurement values of physics tests exceed the design or safety limits,review and evaluation m...
