Simulation of loss of main and auxiliary feedwater event (Davis-Besse) using MAAP-DOE WBS 3. 6. 10. 2
This report documents the benchmarking effort of the MAAP-DOE code against the loss-of-feedwater incident at the Davis-Besse Nuclear Power Plant (DBNPP) - Unit 1. A comparison is made of time history profiles for key system variables from the DBNPP sequence data and MAAP-DOE code predictions. These key variables are steam generator secondary side pressures and downcomer water levels, primary system pressure and temperature and pressurizer level. These variables are compared for event timing and order and for peak magnitude. Discussion of important differences arising in the comparisons are also presented. The comparisons of the key variables from the simulation resulted in good agreement with the plant data. Minor discrepancies are noted and discussed. Judging from these discrepancies and the overall performance of the MAAP-DOE code, suggestions are made for refinements to the code. 7 refs., 29 figs., 1 tab.
