AARE_ACTIVATION SCRIPT VERSION 2.0 USER GUIDE

AARE_ACTIVATION prepares the input files for various activation codes from MCNPX 1-2 or MCNP6 3 output and runs them. Three activation codes are presently supported: CINDER2008 4 , SP FISPACT 5-6 from the EASY-2010 code package, and ORIHET3 7 . The script assumes that the requested activation code is installed on the computer with all ancillary files and data libraries such that it can be executed through the settings of the PATH environment variable or by defining the absolute path of the executable name in the input of AARE_ACTIVATION.AARE_ACTIVATION is distributed in the AARE code package, which also includes CINDER2008. If the user wants to run the ORIHET3 and SP-FISPACT codes, the user will need to inquire after the respective codes as indicated in the references. In case problems are encountered running AARE_ACTIVATION, the authors would be pleased receiving a report of the problems, including the inputs and names of code versions that were applied.

Recent Improvements To CINDER2008 and Activation Analysis Tools

CINDER2008 is a transmutation code that calculates induced radioactivity for either reactor- or accelerator-driven radiation sources. Several Perl scripts have been developed to treat multi-cell problems in combination with either the radiation transport code MCNPX or a special version of MCNPX that writes residual nuclide tallies from model-based physics directly in the MCNPX output file. These scripts simplify the preparation of CINDER input, and can use CINDER output to prepare the source term for a subsequent MCNPX run to calculate dose rates due to activated material. In addition, these scripts support calculations with the transmutation codes SP-FISPACT and ORIHET-3. A number of improvements have been made to CINDER, its data libraries, and the Perl scripts, including (1) substantial corrections to the data libraries, (2) inclusion of recent revisions to USDOE HC-2/HC-3 thresholds and the corresponding thresholds for regulatory bodies in other countries, (3) the ability to run the CINDER accident analysis tool through the script input file, and (4) an easier way to write the script input file when treating a large number of cells. Some features of running CINDER and a number of example problems are discussed.
