Cinder 90 Transmutation Code Package for Use in Accelerator Applications in Combination with MCNPX.

摘要

CINDER'90, a nuclear inventory code originated at the Bettis Atomic Power Laboratory for reactor irradiation calculations and extended for use of in accelerator dr iven systems and high-energy applications at Los Alamos National Laboratory, has been released as a code package for distribution through the Radiation Safety Information Computational Center (RSICC). The code package and its updated data libraries come with several scripts that allow calculations of multi-cell problems in combination with the radiation transport code MCNPX. A script was developed that manages all the pre-processing steps extracting the necessary information from MCNPX output or from one input file, and that runs the CINDER’90 code for a requested list of MCNPX cells and for a requested time history. A second script was developed that extracts the decay photon sources from CINDER’90 output for a requested list of cells and for a requested irradiation or decay time step and builds source deck for subsequent MCNPX calculations. Since the package release, improvements to CINDER’90 are underway in algorithms, libraries, and interfaces to transport codes.
