压水堆堆芯设计特点及其演变

综合论述了压水堆堆芯设计中的化学补偿反应性、标准化无盒大型燃料组件、棒束型控制棒、可燃毒物和采用多区堆芯装料等基本问题。并以上述５大问题为基础，简要叙述了负荷跟踪运行给堆芯设计带来的有关设计问题。此外，简要介绍了当前压水堆堆芯的改进设计及演变过程。

Reactor Core Characteristics of PWR and Its Evolvement

This paper describes the basic problems of reactor core design of PWR such as chemical shimming reactivity,standardized non cassette fuel assembly,bundle of control rods,burnable poison,multi zone core and so on.The reactor core design requirements are introduced briefly,which resulted form load following operation.The development and evolvement course of current PWR core are also introduced.
