Production of Probability Tables for the Unresolved-Resonance Region Using the AMPX Cross-Section Processing System

摘要

The tasks associated with the 'Development and Applicability of Criticality Safety Software for Licensing Review' are documented in the DOE Laboratory Project and Cost Proposal for NRC Work (JCN W6479). Six tasks are documented that address the upgrade to the AMPX code system. The AMPX upgrade is intended to facilitate independent H processing of Version VI formats of the Evaluated Nuclear Data File (ENDF) using state-of-the-art procedures. Consequently, a comprehensive and alternative processing capability would be available to generate neutron cross-section data for criticality safety licensing applications. Task 8 of the cost proposal addresses the development of the capability to generate probability tables for treating resonance data. To date, a substantial amount of code development is complete, and in accordance with the reporting requirements for Task 8 of the cost proposal, this letter report documents the capabilities for generating probability-table data for neutron transport applications.
