压水堆一回路冷却剂中Ag核素来源及脱除方法研究综述

Review of Sources and Removal Methods of Ag Nuclides in Primary Circuit Coolant of Pressurized Water Reactors

压水堆一回路冷却剂中^(110 m)Ag的含量对核电机组的安全运行有极大的影响,本文对压水一回路^(110 m)Ag来源以及特性做出了一定的总结,通过高温电位E-pH图对^(110 m)Ag在压水堆一回路的存在形态进行了探讨,并对压水堆一回路中^(110 m)Ag的控制与脱除的方法进行总结。

The content of ^(110 m)Ag in the primary circuit coolant of the pressurized water reactor has a great influence on the safe operation of the nuclear power unit.This paper makes a certain summary of the source and characteristics of ^(110 m)Ag in the primary circuit of PWR,and discusses the existence of ^(110 m)Ag in the primary circuit of PWR through the E-pH diagram at normal temperature and high temperature.The control and removal methods of ^(110 m)Ag in the PWR primary circuit are summarized.
