摘要
本文研究了CPR1000机组核电厂主控室应急区域(Main Control Room Emergency Zone,简称CREZ)的可居留性安全分析,分析计算了某核电厂运行期间主控室应急区域人员受到最大剂量对应的非过滤渗漏安全限值为153 m^(3)/h;调研了CREZ正压试验的现状,并提出了采用多个仪表进行CREZ内不同区域的正压测量方案,可实现正压验证和泄漏区域定位;调研了CREZ非过滤渗漏试验的现状,分析了超声波用于CREZ非过滤渗漏点定位的优点;分析了CPR1000机组核电厂主控室应急区域范围内房间功能与标准的要求,提出缩小CPR1000机组主控室应急区域范围的方案,分析认为优化后将会减少CREZ三分之二的边界,平开门数量约减少三分之二。
This paper studies the habitability safety analysis of the Main Control Room Emergency Zone(CREZ)of the CPR1000 Nuclear Power Plant.The safety limit of the unfiltered leakage corresponding to the maximum dose to the personnel in the main control room emergency zone during the operation of a nuclear power plant is 153 m^(3)/h;According to investigation of the current situation of CREZ positive pressure test,and the positive pressure measurement scheme of different areas in CREZ is proposed by using multiple instruments,which can realize positive pressure verification and leakage area location;and the status of unfiltered leakage test in CREZ was investigated,and the advantages of ultrasonic wave is used to locate unfiltered leakage in CREZ were analyzed;Also the paper analyzes the requirements of room functions and standards in the emergency area of the main control room of CPR1000 Nuclear Power Plant,and puts forward a scheme to reduce the emergency area of the main control room of CPR1000 unit.It is analyzed that after optimization,the boundary of CREZ will be reduced by two-thirds,and the number of swing doors will be reduced by about two-thirds.
