摘　　要：秦山CANDU重水堆在顺利开展工业^(60)Co放射源生产的基础上,变更D型钴调节棒为医用调节棒,生产医用^(60)Co。医用钴调节棒在设计上与工业钴调节棒有等效的反应性控制能力,但他们细微的差别还是会对ROP停堆保护参数产生很小的影响。本文计算医用钴调节棒堆芯下的ROP停堆整定值,并与同样工况下工业钴调节棒堆芯下计算的停堆整定值进行比较,分析医用^(60)Co生产对ROP停堆整定值的影响。Based on the successful production of industrial cobalt-60,Qinshan CANDU reactor has changed D type cobalt adjuster as medical cobalt adjuster to produce medical cobalt-60.The medical cobalt adjuster is designed to have similar reactivity control capability with industrial cobalt adjuster,but their slight differences still have very little impact on the ROP shutdown protection parameters.This paper calculated ROP TSP based on medical cobalt adjuster,and compare with the ROP TSP calculated based on same operating condition industrial cobalt adjuster.Finally,the effects on ROP TSP of medical cobalt-60 production are analyzed.
