CARR停堆后重启临界棒位预测

Study on the Critical Rod Position Prediction on CARR after Shutdown and Restarting

利用MVP-BURN程序计算了三种堆芯装载状态下,5〜60 MW功率水平时反应堆的碘坑形态。在确定了碘坑深度和棒栅价值关系的基础上,依托Visual C++6.0平台编写了快速查询程序。实验验证表明,本程序得到的预测临界棒位与实际棒位符合较好,它将为后续反应堆在碘坑中安全启动提供重要参考依据。

The iodine pit configuration from 5 MW to 60 MW at 3 core loading states has been calculated by MVP-BURN program.Based on the iodine pit depth and rod lattice worth calculated,the Visual C++6.0 platform was used to develop a quick search program.Experiments have shown that the prediction has good coincidence between the calculated rod position and the real operation value.It will provide an important reference for the safe start-up of the reactor in iodine pit later.
