摘要/Abstract

摘要： 压水堆核电厂通常采用天然硼进行反应性的化学补偿控制,研究表明采用富集硼替代天然硼,可以优化一回路水化学,降低一回路结构材料腐蚀风险和堆芯沉积风险,降低职业照射剂量。本文分析压水堆核电厂采用富集硼的优势与可行性,介绍国内外核电厂富集硼的应用情况。最后对我国华龙一号堆型和在役压水堆核电厂富集硼的应用提出建议。

关键词: 富集硼, 水化学优化, 职业照射剂量, 华龙一号, 注锌

Abstract: Natural boron is widely used for chemical compensation control of reactivity in PWR. Research shows enriched boron, as an alternative of natural boron, can optimize the primary loop hydrochemistry and therefore reduce the materials corrosion risk of primary loop structure and core deposition risk. It reduces the occupational exposure dose as well. This paper analyzes the advantages and feasibility of using enriched boron in PWR. It introduces the practical application of enriched boron in both domestic and overseas PWRs. Finally, suggestions are proposed on the application of enriched boron for HPR1000 and domestic operating PWRs.

Key words: enriched boron, hydrochemistry optimization, occupational exposure dose, HPR1000, zinc injection
