Reactor Axial Power Distribution Control for PWR Nuclear Power Plant

本文介绍了采用低维等效原理和综合法技术,研制成功的压水堆轴向功率偏移控制和负荷跟踪计算程序。该程序为我国秦山二期2×600MW 核电厂反应堆的核设计提供了急需的计算手段。程序的计算精度满足工程设计的要求。本文还利用此程序完成了该反应堆负荷跟踪计算和各种典型的运行功率瞬态分析,初步确定了该反应堆的运行控制方式和轴向功率偏移的安全保护定值。

This paper introduces a computer code developed for reactoraxial power offset control and lood following calculation basedon low-dimensional equivalent principle and synthesis technique.The code privides calculational means needed urgently for nucleardesign of 2×600MW reactor of Qhinshang NPP-2.The calculationprecision of the code is in agreement with that of the require-ment for engineering designs.In addition,using the code,the loadfollowing calculation and various typical operating power transi-ent analysis of the 600MW nuclear power plant reactor have beenfinished and an operational control mode and axial power offsetsafety protective setting values of the reactor have been prelim-inary established.
