摘要

光纤辐射探测系统（OFPS）是一种用于湿池乏燃料束物理库存验证（PIV）的验证设备。在这项研究中，研究了使用ORIGEN代码和Geant4工具包生成PIV辐射剖面的蒙特卡罗模拟方法，以评估OFPS的性能。(1)利用ORIGEN代码计算乏燃料束的放射性；(2)利用Geant4模拟模拟湿池环境，计算各束对探测器信号的贡献。(3)利用两个数据集生成了PIV的辐射廓线。将生成的轮廓与实验轮廓进行了比较，结果表明两者吻合较好。所提出的仿真方法有望实现对OFPS测量结果的预测和对OFPS性能的评估。

Modeling and simulation of radiation profiles for spent fuel verification using OFPS in wet storage pools

Optical Fiber radiation Probe System (OFPS) is a verification equipment for physical inventory verification (PIV) of spent fuel bundles in the wet storage pools. In this study, a Monte Carlo simulation method using the ORIGEN code and Geant4 toolkit to generate the radiation profile for PIV was investigated to evaluate the performance of the OFPS. (1) The radioactivity of spent fuel bundles was calculated using ORIGEN code, (2) the wet storage pool environment was modeled using Geant4 simulations, and the contribution of each bundle to the detector signal was calculated. (3) The radiation profiles for PIV were generated using both data sets. The generated profile was compared to the experimental profile and demonstrated a close match. The proposed simulation method is expected to enable the prediction of OFPS measurement results and evaluate the performance of the OFPS.
