压水堆一回路系统水化学控制的探讨

A Study on the Primary Circuit System Water Chemistry Control of The PWR Nuclear Power Plant

通过对压水堆核电厂一回路系统主要材料和腐蚀类型的分析,结合一回路水化学特性,探讨压水堆普遍采用的水化学控制措施,如硼-锂协调pH控制、一回路冷却剂水质控制、堆芯外辐射场控制等,寻求优化一回路水化学控制方法,维护反应堆的安全运行,提高核电站的可利用率。

This essay introduces the main materials and different corrosion forms in the PWR primary circuit system. Based on the characteristics of the primary circuit water chemistry, this essay also analyzes the water chemistry control methods generally used in the PWR such as the coordinated pH control of boron acid and lithium hydroxide, the coolant water quality control and the radiation field control outside the reactor core. The purpose is to find a way to optimize the primary circuit water chemistry control, maintain the safe operation of the reactor, and increase the availability of the nuclear power plant.
