国内外核电凝结水精处理树脂差异分析研究

Analysis and Study on the Differences in Resin for Nuclear Power Condensed Water Treatment between Domestic and Foreign Countries

摘要: 核电厂凝结水精处理系统的主要功能是去除凝结水中的杂质，确保二回路系统水质。我国目前核电厂凝结水精处理系统用的离子交换树脂几乎为进口品牌，国内品牌的实际应用案例极少。本文选取了国内使用频率较高的进口凝胶均粒树脂与国产具有代表性的凝胶均粒树脂进行指标检测，对比分析国内外树脂指标的差异，为凝结水精处理系统用树脂国产化提供数据支持。

Abstract: The main function of the condensate polishing system in a nuclear power plant is to remove impurities from the condensate and ensure the water quality of the secondary loop system. At present, most of the ion exchange resins used in the condensate polishing system of nuclear power plants in China are imported brands, and there are very few practical application cases of domestic brands. This article selects imported resins with high frequency of use in China and representative domestically produced condensate polishing resins for index testing, and compares and analyzes the differences in resin index between domestic and foreign resins, and provide data support for the localization of resin used in condensate polishing systems.
