本文簡要介紹了堆芯燃料管理所使用的計算程序,討論了堆芯燃料的装載及更換方式、燃料加浓度的选择、每次換料时更換燃料組件的数量、备用燃料的选择、循环寿期的选定以及堆芯延迟換料的运行等。对其中一些內容計算了几种方案以进行比较。由計算结果可以看到影响經济利用核燃料的各种因素,在設計电站压水堆时需要綜合考虑,恰当选择。 This article gives a brief overview of the calculation procedures used in core fuel management, discusses ways to load and replace core fuel, the choice of fuel plus concentration, the number of fuel assemblies to replace each refuel, the choice of spare fuel, the cycle life The choice of period and the operation of the reactor core refueling delay. Several of these programs have been calculated for comparison. From the calculation results, we can see the various factors that affect the economical utilization of nuclear fuel. When designing the pressurized water reactor for power station, we need to consider synthetically and select properly.
