Comparison of COMPARE and BEACON subcompartment analyses of Battelle-Frankfurt containment tests. [PWR]
This report presents the results of computations performed with the COMPARE/MOD1 and BEACON/MOD3 computer codes for selected Battelle-Frankfurt loss-of-coolant accident experiments. COMPARE is used widely to perform nuclear power plant containment subcompartment analyses, and BEACON is an advanced multiphase, multidimensional best-estimate code. The objective of this study was to evaluate the margins of COMPARE calculations by comparing them with BEACON calculations and test data. The calculations were performed for the Battelle-Frankfurt D3, D6, and C9 tests. Descriptions of the two codes and the Battelle-Frankfurt experiments are included. Comparisons of the codes' calculations and experimental data for absolute pressure, differential pressure, and temperature are presented for margin evaluation. Evaluations of the sensitivity of BEACON calculations to variations in model noding, form loss, and vent area modeling are prsesented. Conclusions summarizing the results of the COMPARE margin evaluation and BEACON sensitivity studies are given as well.
