ARP: Automatic rapid processing for the generation of problem dependent SAS2H/ORIGEN-S cross section libraries

摘要

In this report, a methodology is described which serves as an alternative to the SAS2H path of the SCALE system to generate cross sections for point- depletion calculations with the ORIGEN-S code. ARP, Automatic Rapid Processing, is an algorithm that allows the generation of cross-section libraries suitable to the ORIGEN-S code by interpolation over pregenerated SAS2H libraries. The interpolations are carried out on the following variables: burnup, enrichment, and water density. The adequacy of the methodology is evaluated by comparing measured and computed spent fuel isotopic compositions for PWR and BWR systems.
