Data from Geant4 calculations of average gamma heating from selected cases of used light water reactor nuclear fuel assemblies in a KBS-3 type deep geological repository

Monte Carlo calculations, using the Geant4 framework version 10.02 [1], of energy deposition from gamma radiation emitted from light water reator fuel assemblies in a KBS-3 type deep geological repository for used nuclear fuel has been performed. Selected cases of boiling and pressurized reactor fuel assemblies from the "SKB-50" set of fuel assemblies were used; "BWR1", "BWR6" and "PWR8" [2]. An isotropic source of gamma-rays with energies of 444, 662, 723 and 1274 keV, depending of the case, were distributed homogeneously in the intersection of a (mid-)plane perpendicular to the canister central axis with all the fuel rods in all fuel assemblies in the canister. The average energy deposition in a 3-dimensional (x,y,z) mesh with 1 cm resolution was calculated per emitted gamma particle. This dataset contains the resulting meshed energy deposition data. Description of files: - The gzip compressed tar file contains comma-separated-values (CSV) files with the data "mesh x position [cm], mesh y position [cm], mesh z position [cm], average energy deposition per emitted gamma [MeV]" supplied on each row. The name of the CSV file specifies the fuel assembly id from the SKB-50 set of fuel assemblies as well as the energy of the emitted gamma radiation. - The txt-file contains the SHA-256 checksum of the gzip compressed tar file. The dataset was originally published in DiVA and moved to SND in 2024.本研究采用Geant4框架10.02版本[1]，针对KBS-3型乏核燃料深层地质处置库中轻水反应堆燃料组件发出的γ辐射能量沉积开展蒙特卡洛计算。选取“SKB-50”燃料组件套件中的沸腾水堆与压水堆燃料组件案例，具体为“BWR1”、“BWR6”及“PWR8”[2]。 根据不同案例，采用能量为444、662、723与1274 keV的各向同性γ射线源，将其均匀分布在与容器中心轴垂直的（中）平面与容器内所有燃料组件中全部燃料棒的相交区域内。针对每个发射出的γ粒子，计算分辨率为1 cm的三维（x,y,z）网格中的平均能量沉积。本数据集包含最终得到的网格化能量沉积数据。 文件说明： - 该gzip压缩tar包包含逗号分隔值（CSV）文件，每行数据格式为"网格x坐标[cm]、网格y坐标[cm]、网格z坐标[cm]、每个发射γ粒子的平均能量沉积[MeV]"。CSV文件名会标注SKB-50套件中的燃料组件编号，以及发射的γ辐射能量。 - 该txt文件包含该gzip压缩tar包的SHA-256校验和。 本数据集最初发布于DiVA平台，并于2024年迁移至SND。
