摘要/Abstract

摘要： 石岛湾高温气冷堆为示范电站，其蒸发器采用特有的组件式直流螺旋盘管结构，二回路水质控制既无相关行业技术标准，也无成熟运行经验可借鉴。在参考火电直流机组和压水堆规范及其运行经验基础上，结合高温气冷堆二回路结构和材料特点，对机组启动冷态冲洗和热态冲洗控制方式、加药控制、凝结水精处理系统运行方式等进行了探讨，提出了完整的高温气冷堆二回路水汽品质优化方法。该方法经专家充分讨论并认可，已编入高温堆调试大纲和运行规程。

Abstract: Referring to the thermal power plant DC unit and the pressurized water reactor standards as well as the operation experiences and in view of the secondary circuit structure and material features of the high temperature gas-cooled reactor, this paper studies three methods of controlling the secondary circuit water quality of the high temperature gas-cooled reactor, which include dosing control, the operation method of the condensate water polishing system and system flushing before unit start-up. In the end, the three methods are discussed in detail, and a scientific and complete method for optimizing the quality of water and steam in the secondary circuit of the high temperature gas-cooled reactor is formed. The method is discussed and approved by the experts, and is compiled into the commissioning outline and the operation rules for the high temperature reactor.

Key words: nuclear power plant, high temperature gas-cooled reactor, the secondary circuit, quality of steam and water, system flushing, operation method of condensate water polishing system
