A Scheme for Establishing of Criterions for Reactor Safe Operation in Condition of Fuel Clad Failure
-
摘要: 运行判据是用于判断反应堆燃料元件发生破损时能否继续运行的指标条件,本文提出建立反应堆燃料元件破损运行判据的思路和方法,通过风险分析,确定监督运行最大容许破损数量;研究提出既能反映燃料元件破损数量又可直接监测的指标参量,并建立破损数量与可监测指标参量之间的对应关系;将最大容许破损数量对应的可监测指标参量值作为运行技术判据。Abstract: Operation criterions are used to decide if the reactor can continue to work when the fuel clad failure.The method for establish the limits is presented.The tolerated maximum of failure fuel rods for the reactor safety should be calculated by risk analysis.The parameters are determined which can not only reflect the quantity but also be measured directly.The relationship is set up between the amounts with the parameters.The data calculated corresponding to maximum of failure fuel element which the reactor safety can stand are technical limits used to decide if the reactor can work continually.
