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.
