摘　　要：为生产医用60Co同位素,首批医用59Co调节棒在秦山第三核电厂一号机组109大修期间更换入堆芯。为验证新换入的医用钴调节棒是否满足设计要求,并确保换入新调节棒后的反应堆运行于安全状态,组织实施了一系列物理验证试验,包括调节棒价值测量、堆芯通量监测等。通过验证,最终结果符合要求。经过上述试验,确认新调节棒性能与原调节棒相当,换入新调节棒后的堆芯通量分布和功率分布均符合要求,反应堆运行于安全状态。In order to produce the medical cobalt-60 isotope,the first batch of medical cobalt-59 adjuster rods were loaded into the core during the 109 outage of Qinshan 3.To verify whether the performance of the new medical cobalt adjuster rod meets the design requirement,and to ensure that the reactor is operating in a safe condition after the replacement,Qinshan has organized and implemented a series of reactor core physical tests,including the adjuster rod value measurement and the core flux monitoring,etc.Test results confirmed that the performance of the new adjuster rod is the same as the original one,and the reactor is operating in a safe condition after the replacement.
