RELAP4/MOD6 prediction comparisons with LOFT LOCE L2-3 data. [PWR]

Technical Report ·
OSTI ID:6024448
A comparison is presented between RELAP4/MOD6 predicted and experimental measured quantities for Loss-of-Coolant Experiment (LOCE) L2-3 performed in the Loss-of-Fluid Test (LOFT) facility. These data comparisons provide a detailed record for subsequent analysis. Comparisons indicate that the trends in the system hydraulic response were generally well predicted. The core thermal response, in general, was not well predicted due to the code failing to predict the early rewet. It is recommended that future LOCE L2-3 posttest analysis efforts be centered on gaining a better understanding of modeling rewet phenomena with the RELAP4/MOD6 heat transfer surface. Better modeling of the performance of the steam generator secondary side is also needed before modeling small break LOCEs.
