Title: Loss-of-Coolant Accident Test Series Test LOC 5 Experiment Predictions

Technical Report ·
DOI:https://doi.org/10.2172/5958148· OSTI ID:5958148

The Loss of Coolant Accident (LOCA) Test Series being conducted in the Power Burst Facility (PBF) at the Idaho National Engineering Laboratory has been designed to provide data for the development and the assessment of fuel behavior computer codes used to predict the response of a pressurized light water reactor (PWR) during a hypothetical break in the cold-leg inlet or hot-leg outlet. This report presents the experiment predictions for the four-rod LOCA test, LOC-5. An analysis was performed to predict the test fuel rod and system behavior during a typical LOC test. Reactor physics calculations were performed with the RAFFLE code to determine the relationship between test fuel rod powers and the PBF reactor power during both the steady state operation and during the blowdown. Calculation of the system thermal-hydraulic response during blowdown, made with the RELAP4 computer code, provided the coolant and heat transfer boundary conditions for the fuel behavior calculations. Cladding and fuel rod dimensions for the rods previously irradiated in the Saxton reactor were determined with the FRAP-S code. Finally, the rod thermal and mechanical behavior during the blowdown transient were determined with the FRAP-T5 code.
