摘要
秦山二期目前采用的是使用36盒富集度为3.7%的换料组件的OUT-IN年换料燃料管理策略,从2号机组第11燃料循环开始第1个长循环过渡,采用的是使用44盒富集度为4.45%的换料组件的IN-OUT长循环燃料管理策略。为解决目前长循环燃料管理策略循环长度偏短、预留停堆维修时间较长、电站可利用率较低等问题,对使用48盒富集度为4.45%的换料组件的IN-OUT长循环燃料管理策略进行了研究。通过对上述3种燃料管理策略的主要计算结果进行分析和比较,推荐秦山二期长循环燃料管理采用48盒富集度为4.45%的燃料管理策略。
Currently,the annual and OUT-IN reloading strategy is used in QinshanⅡ NPP,which employs 36 new assemblies with 3.7% enrichment.The long-cycle fuel management strategy which uses IN-OUT reloading method and employs 44 fresh assemblies with 4.45%enrichment,is adopted in unit 2cycle 11（U2C11）.A long-cycle fuel management strategy,adopting IN-OUT reloading method and 48 fresh assemblies with 4.45%enrichment,was presented.The purpose of presented strategy is to extend the cycle length,shorten shutdown time and exalt the utilization rate of power plant.The main attributes of these three fuel management strategies were analyzed and compared.As a result,the presented long-cycle fuel management strategy is the optimized strategy.
