可视化监控在核电厂热态性能试验期间防烫伤中的应用陈帅江1,周梦雄2(1.万纳神核控股集团有限公司,浙江嘉兴314300;2.中国核电工程有限公司华东分公司,浙江嘉兴314300)摘要:核电厂热态性能试验是电厂整个调试期间安全风险最高的阶段,调试人员与建安人员高度交叉,易发生群死群伤事故,其中高温蒸汽烫伤事件占有较高比例。为减少热态性能试验期间,高温蒸汽烫伤事件的发生,对比各核电厂防烫伤措施,说明可视化监控在防烫伤方面的优势,并对两种常用可视化监控方案进行分析。根据分析结果,可视化监控应用在卡拉奇核电厂各类高风险作业中,期间未发生高温蒸汽烫伤事件,安全管控效果良好,对其他在建核电厂具有较大的借鉴意义。关键词:可视化监控;热态性能试验;防烫伤中图分类号:TM623DOI:10.19768/j.cnki.dgjs.2023.02.052ApplicationofVisualMonitoringinScaldPreventionDuringThermalPerformanceTestinNuclearPowerPlantCHENShuaijiang1,ZHOUMengxiong2(1.WannaShenheHoldingGroupCo.,Ltd.,Jiaxing314300,China;2.ChinaNuclearPowerEngineeringCo.,Ltd.,EastChinaBranch,Jiaxing314300,China)Abstract:Thethermalperformancetestofnuclearpowerplantisthestagewiththehighestsafetyriskduringthewholecommissioningperiodofthepowerplant.Thecommissioningpersonnelarehighlycrossedwiththeconstructionandin-stallationpersonnel,whichispronetomasscasualties,ofwhichhigh-temperaturesteamburnsaccountforahighpropor-tion.Inordertoreducetheoccurrenceofscaldcausedbyhigh-temperaturesteamduringhotperformancetest,theanti-scaldmeasuresofnuclearpowerplantswerecompared,theadvantagesofvisualmonitoringinanti-scaldwereillustrated,andtwocommonvisualmonitoringschemeswereanalyzed.Accordingtotheanalysisresults,itisusedinvarioushigh-riskoperationsoftheKarachinuclearpowerplant.Duringthisperiod,nohigh-temperaturesteamscaldingincidentoc-curred,andthesafetycontroleffectwasgood,whichhasgreatreferencesignificanceforothernuclearpowerplantsunderconstruction.Keywords:visualmonitoring;thermalperformancetest;anti-scald收稿日期:2022-05-060引言热态性能试验(以下简称热试)是在尽可能模拟核电厂实际运行工况的条件下,验证系统的热态性能是否与设计规定要求一致,验证系统和设备在高温运行时的可靠性,在高温下对设备和管道内壁...
