摘要
宁德核电站一号机组作为世界首例首循环采用钆作为可燃毒物的大型商用压水堆,堆芯首次启动物理试验是检验堆芯设计的重要依据。本文叙述了宁德核电站一号机组反应堆首次启动物理试验理论分析模型、程序和计算结果与测量值的比较。结果表明,理论预计值与实测结果符合良好,偏差均满足验收准则。
The gadolinium is used as the burnable poison for the first cycle of Unit 1 of Ningde Nuclear Power Plant, and it is the first time to apply it on a commercial PWR in the world. The results of the first startup physics test are very important for evaluating the core design. This paper describes the calculation methods, codes and comparisons between the calculation values and experimental results for the first reactor startup physics test. The results showed that the calculated theoretical values are consistent with the measured values.
