摘要/Abstract

摘要： 余热排出系统的辐射水平在机组停堆过程中会明显变化,氧化运行期间达到停堆峰值,对周边区域产生影响。对“华龙一号”余热排出系统停堆峰值时刻周边区域的辐射水平进行了计算,对比运行电厂实测最大值,综合分析给出了余热排出系统对周边区域辐射水平的影响,同时提出了相应的优化建议。

关键词: “华龙一号”, 余热排出系统, 氧化运行, 停堆峰值

Abstract: The radiation level of residual heat removal system will change significantly during reactor shutdown, and will reach the shutdown peak during oxygenation, which will affect the surrounding area. In this paper, the surrounding area radiation level of the HPR1000 residual heat removal system is calculated and compared with the measured maximum value. The influence on the radiation level in the surrounding area of residual heat removal system is analyzed comprehensively, and the corresponding optimization suggestions are put forward.

Key words: HPR1000, residual heat removal system, oxygenation, shutdown peak
