| 摘 要： | 针对外推临界试验中应用控制棒价值的效果进行研究。在零功率反应堆上进行外推临界试验,基于外推临界试验中子计数,采用考虑和未考虑控制棒价值的外推方法进行分析。结果表明:在前几步外推临界过程,控制棒价值对外推临界棒位的影响较为明显,对指导外推提棒存在一定影响,未考虑控制棒价值的外推1/2添加棒位会出现超过临界棒位的情况;在外推临界过程中,考虑控制棒价值的外推方法更加准确,所得外推结果更加安全。

| Abstract: | The application effect of the control rod worth in the criticality extrapolation experiment is studied. The criticality extrapolation experiment is conducted on a zero power reactor, and the analysis is carried out by 2 extrapolation methods, i.e., with and without the consideration of the control rod worth, based on the neutron count rate data. The results indicate that the control rod worth is with great effect on the extrapolation results in the first few extrapolation steps, and the extrapolation 1/2 adding control rod position would exceed the measured critical control rod position without taking consideration of the control rod worth. The extrapolation method taking the control rod worth into consideration is more precise, with better results. |
