本文简述我国正着手建设的30万千瓦压水堆核电站的设计特点。反应堆堆芯的水-铀体积比(V_(H_2O)/V_(uo_2)为2.0653。堆芯中UO_2燃料的总装载量为40.744t.第一个堆芯有三种不同的~(235)U浓度,即:2.4％、2.672％、3％,以后平衡换料的燃料浓度为3％。反应堆冷却水的压力为155kg/cm~2,平均温度为302℃,额定流量为24000t/h。采用棒束型控制棒和溶硼两种方式进行反应性控制。第一回路由两个环路组成,每个环路有一台冷却水主泵和一台蒸汽发生器。反应堆设有15个以上的辅助系统以保证它的正常运行、安全防护和环境保护。从核供汽系统向汽输机供应饱和蒸汽的流量为1871～2020t/b,压力为53.0～56.5kg/cm~2,这些蒸汽可生产300MW或300MW以上的电力。为了论证和肯定设计,进行了大量的研究试验工作,并取得了满意的结果。
This article briefly describes the design features of the 300,000 kilowatt pressurized water reactor nuclear power station under construction in our country. The reactor core has a volume ratio of V_ (H_2O) / V_ (u_o) of 2.0653. The total loading of UO_2 fuel in the reactor core is 40.744t. There are three different concentrations of ~ (235) U in the first reactor , Namely: 2.4%, 2.672%, 3%, after the balance of refueling fuel concentration of 3% reactor cooling water pressure of 155kg / cm ~ 2, the average temperature of 302 ℃, rated flow of 24000t / h. Beam control rod and boron dissolved boron two ways for the reactivity control.The first loop consists of two loops, each loop has a cooling water main pump and a steam generator.The reactor has more than 15 auxiliary System to ensure its normal operation, safety protection and environmental protection.The supply of saturated steam from the nuclear steam supply system to the steam turbine is 1871 ~ 2020t / b and the pressure is 53.0 ~ 56.5kg / cm ~ 2, and these steam can be produced 300MW or more of electricity.In order to demonstrate and affirmative design, a large number of research experiments have been carried out and satisfactory results have been obtained.
