摘　　要：秦山二期核电厂反应堆堆芯核设计吸取了近年来压水堆电厂先进的设计思想，采用低线功率密度堆芯，提高了堆芯的安全裕度；不同富集度的燃料组件和可燃毒物的合理布置，改进了堆芯的物理特性；采用ＯＵＴ－ＩＮ、四分之一换料方式提高了燃料利用率，卸料比燃耗达到３５ＧＷ·ｄ／ｔ（Ｕ），同时满足了年换料制的要求．采用了先进的和经过验证的计算方法和计算机程序，这些程序经受了大亚湾和秦山核电厂数据的设计检验，因而提高了设计的可靠性。在设计中体现了先进性、安全可靠性和经济性的特点．Reactor core nuclear design of Qinshan-Ⅱ NPP adopts the ad.anced PWR design ideas that appeared recently, The low linear power density is used in the core design to increase the core safety marginl it gives the reasonable arrangement of different enriched fuel assemblies and burnable poison reds to improve the core physical characteristicsl and the core also uses one fourth OUT-IN reload manner to make full use of the fuel. The discharged burnup will reach 35GW. d / t(U) and satisfy the requirement of annual reload mode. The calculating method and the design codes are advanced and were verified by many strict calculations. From the results of Daya-Bay NPP and Qinshan-Ⅱ NPP calculated by use of thses codes, we can holieve that the codes are reliable in Qinshan-Ⅱ align. The design shows that the core is advanced, safe and economical.
