Comparison of RELAP5/MOD1.6, TRAC-BD1/Version 12, and TRAC-BD1/MOD1 Assessments with Data from a ROSA III Small Break Test

摘要

A comparative analysis of three assessment studies of Run 912 from the ROSA-III small break LOCA test series has been performed. Two of the studies were done using the TRAC-BD1 computer code, while the RELAP5 code was used for the third study. The studies are part of INEL's support to the United States Nuclear Regulatory Commission for the independent assessment of reactor safety codes. The ability of each computer code to calculate pertinent thermal-hydraulic phenomena in the experiment is presented. The run time assessment statistics are also presented. (ERA citation 10:008618)
