摘要
根据大亚湾核电站实测数据及法国电力公司（ＥｄＦ）提供的某些数据，从反应性平衡方程出发，应用核设计软件分析研究引起象限功率倾斜比超限的根本原因。针对此根本原因提出了降低三环路压水堆核电站换料堆芯象限功率倾斜的方法，并在大亚湾核电站第４循环的设计中得到证实。发展了一种模拟象限功率倾斜的数值模型及预测换料堆芯象限倾斜比的方法。与实测数据相比，预测值的精度是令人满意的。
Based on the measured data of Daya Bay Nuclear Power
Station and EdF and using reactivity balance equation, the fundamental cause of QPTR(Quadrant
Power Tilt Ratio) overstepping for reload core of PWR nuclear power plant was found. Some
numeral models of QPTR and a method predicting QPTR of reload core were developed. A simple
method reducing QPTR of reload core was recommended. The measured data of reload cores
proved that the recommended method reducing QPTR is practicable.
