压水反应堆的重新加载启动物理试验

[中文适用范围]： 本文件适用于需要核设计计算的压水堆换料或其他堆芯改造后进行的反应堆物理测试。 本文件不涉及商业压水堆初始堆芯的物理测试程序。 本文件规定了可接受的最低启动反应堆物理测试程序，以确定堆芯的运行特性是否与设计预测一致，从而保证堆芯可以按设计运行。 本文件不涉及运行期间反应堆物理参数的监视或其他所需的测试，例如系统组件的机械测试（例如，棒下落时间测试）、燃料组件装载的目视验证要求或仪器或控制系统的校准（尽管这些测试是整个程序的一个组成部分，以确保核心按照设计运行）。 [外文原描述]： This document applies to the reactor physics tests that are performed following a refuelling or other core alteration of a PWR for which nuclear design calculations are required. This document does not address the physics test program for the initial core of a commercial PWR. This document specifies the minimum acceptable startup reactor physics test program to determine if the operating characteristics of the core are consistent with the design predictions, which provides assurance that the core can be operated as designed. This document does not address surveillance of reactor physics parameters during operation or other required tests such as mechanical tests of system components (for example, the rod drop time test), visual verification requirements for fuel assembly loading, or the calibration of instrumentation or control systems (even though these tests are an integral part of an overall program to ensure that the core behaves as designed).
