摘要
通过对共轭输运法的研究,采用二维离散纵标程序计算某三代核电厂反应堆满功率运行状态下的堆外探测器响应函数,计算结果与原有数据相比,径向响应因子的相对偏差在3%以内,轴向响应因子的相对偏差在1%以内。表明所采用的计算模型和方法正确。将共轭输运法计算堆外探测器响应的方法在岭澳二期核电项目上进行验证,并与岭澳二期核电工程中采用正向输运法计算的响应因子进行对比,结果表明2种方法的计算偏差不超过5%,验证了共轭输运法与正向输运法计算结果的等价性,但共轭输运法计算效率更高。
Based on the adjoint transport technology, the ex-core detector response function under the full power operation of one third-generation reactor is calculated by using the two-dimension SN code. Calculation results are compared with the original data, and the radial weighting factors would not exceed 3%, and the axial weighting factors would not exceed 1%.The result of this calculation proves that the calculation model and method is correct. The technology has been validated in the Ling＇ao Phase II Nuclear Power Plant. Compared to the numerical result of the radial weighting factors via SN forward Transport Method, it shows that the calculation results difference of the two methods would not exceed 5%. It proves that the result for the two methods is identical and the computational efficiency of the Adjoint Transport Method is more efficient.
