Data for "Development and Benchmark Calculations of Monte Carlo Transport Program MATS for R&D of Accelerator-Driven System"

1. Data Generation and Processing MethodsData Generation Method:​ The data in this dataset were generated through Monte Carlo particle transport simulations performed on computers. The simulations were executed using multiple Monte Carlo programs, including the MCNPX program, the Geant4 program, the PHITS program, and the independently developed MATS program.Processing Steps:Model Setup:​ Input decks for the OECD-ADS, IAEA-ADS, and JAEA-ADS benchmark models were constructed.Simulation Execution:​ The simulation programs were run using these input decks to produce raw statistical results (tallies).Data Extraction and Conversion:​ The raw output was directly read and converted into CSV format files using Python scripts for easier access and analysis.Software and Tools:Simulation Programs:​ MCNPX, Geant4, PHITS, MATS.Post-processing Tool:​ Python scripts (specific versions not provided; recommended to specify if known).Tally Card Format:​ The XML-based tally definitions conform to the schema used by OpenMC version 0.14.0. The specific tally definitions for all results can be found in the /tools/input_tally_xml_card/tally.xmlfile.2. Spatial InformationSpatial Characteristics:​ The data are spatial grid data representing physical quantities across different zones of the simulated Accelerator-Driven System (ADS) models. The dataset does not contain temporal information.Spatial Resolution:​ Different spatial meshes (varying in size and distribution) were employed for the different benchmark models (OECD-ADS, IAEA-ADS, JAEA-ADS). The exact grid geometry and resolution for each tally are defined within the corresponding XML tally cards located in the /tools/input_tally_xml_card/directory.3. Data Content and StructureThe dataset is organized in the /datadirectory, containing three subdirectories:/JAEA-ADS model: Simulation results for the JAEA-ADS model./IAEA-ADS model: Simulation results for the IAEA-ADS model./OECD-ADS model: Simulation results for the OECD-ADS model.Each model directory contains results in a target-simulation/subdirectory. The data files are CSV tables containing 2D grid data.Data Format:​ CSV (Comma-Separated Values).Grid Structure:​ In the CSV files, rows correspond to the r-direction​ (radial direction) and columns correspond to the z-direction​ (axial direction) of the cylindrical coordinate system used in the models.File Naming Convention:Prefix:​ Indicates the simulation program(s) used.Example: MATS_h.csv(Simulated using the MATS program).Example: MCNPX_MATS_h.csv(Simulated using an external coupling method, where the target was calculated by MCNPX and the core by MATS).Suffix:​ Indicates the physical quantity tallied._h: Heating._n: Neutron fluence._p: (if present) Proton fluence._leak: Neutron leakage yield data.Visualization:​ Image files (if present) are provided as visual representations of the CSV grid data.4. Data QualityStatistical Error:​ The relative statistical error associated with the Monte Carlo simulation results is below 1% for the reported tallies. This error is inherent to the Monte Carlo method and decreases with the number of simulated particle histories.Data Missingness:​ There are no explicitly identified missing data points within the generated CSV files. The input decks for the benchmark models themselves are not provided due to copyright restrictions, as noted in the original description (/tools/contains methodological definitions but not the proprietary model geometries).5. File Description/data/[Model Name]/target-simulation/directories: Contain the core result CSV files for each model and simulation type (e.g., MCNPX_h.csv, MATS_n.csv)./tools/input_tally_xml_card/tally.xml: Provides the definitive definitions (geometry, type, etc.) for all tallies (mesh1, etc.) used in the simulations. This file is essential for interpreting the grid data in the CSV files correctly.6. Software Information (for less common formats)The primary data is in CSV format, which is universal and can be opened with any text editor or spreadsheet software (e.g., Microsoft Excel, LibreOffice Calc).The tally definitions are in XML, which can be viewed with any text editor or browser.No specialized or小众 software is required to access the core data provided in this dataset.
