BENCHMARK OF SIMULATE-3K AGAINST THE FRIGG LOOP STABILITY EXPERIMENTS

SIMULATE-3K is used by many utilities for the prediction and analysis of BWR stability events. In recent years, several enhancements of the SIMULATE-3K channel and vessel thermal-hydraulic model have been made. This paper summarizes the status of the SIMULATE-3K core thermal-hydraulic model and presents results of the validation against the OF64 test section experiments performed in the Frigg loop. The results comprise comparisons of channel pressure drops, void measurements, and stability limits.
