核电厂一回路硼碱曲线的研究

Study of boron alkali curve in primary loop of nuclear power plant

硼碱曲线是核电厂一回路水化学的重要控制依据,选择科学合理的硼碱曲线,对于减少一回路腐蚀产物的沉积和放射性源项具有重要的意义。本文分析了一回路水化学控制的目的及一回路pH T选择需考虑的因素,回顾了硼碱曲线的发展历史,重点对国内不同堆型硼碱曲线的特点进行了总结,最后对国内核电厂硼碱曲线的应用给出建议。

Boron alkali curve is an important control basis for water chemistry in the primary loop of nuclear power plant.Selecting a scientific and reasonable boron alkali curve is of great significance to reduce the deposition of corrosion products in the primary loop and the reduction of radioactive source terms.This paper first analyzes the purpose of primary loop water chemistry control,and analyzes the factors considered in the selection of primary loop pHT;secondly,this paper reviews the development history of boron alkali curves,focusing on the analysis of the characteristics of boron alkali curves of different reactor types in China;and finally,suggestions for the application of boron alkali curves in domestic nuclear power plants is put forward in this paper.
