田湾核电厂一回路水化学优化与辐射源项控制

Chemical optimization and radiation sources control of primaryloop water in Tianwan Nuclear Power Plant

压水堆核电厂一回路辐射场的影响因素众多,主要有两个方面,一是系统设备的材料,二是一回路水化学参数。本文对田湾核电厂溶解H_2、硼碱协调曲线控制、注Zn技术、停堆氧化对辐射源项的影响进行探讨,最后提出建议。

Among many factors influencing radiation fields at primary loop of nuclear power plants, two main aspects are the materials of system equipment and the chemical parameters of primary loop water. The effects of dissolution H2 , boron potassium coordination curve control, technology for Zn injection , and reactor shutdown oxidation operation on radiation sources are discussed in this paper. Relevant adviccs are provided.
