Comparison of experimental results with RETRAN predictions for LOFT test L2-3 (NRC Standard Problem 10)

This report documents the ITI/EPRI prediction of Standard Problem 10 for submittal to the United States Nuclear Regulatory Commission. The analysis and submittal were completed prior to NRC's release of test data. The RETRAN computer code and state-of-the-art models were used to analyze the first 20 seconds of LOFT Test L2-3 which was a 200% cold leg break blowdown of a nuclear heated core at a nominal power of 36.7 MW. The experimental data were added to this report after submittal of the prediction and are shown in overlay comparison plots with the RETRAN prediction parameters
