Abstract
Six LOFT transient tests with scram (L6-1, L6-2, L6-3, L6-7, L6-8B-1, and L6-8B-2) and two anticipated transient tests without scram (L9-3 and L9-4) have been analyzed using a best-estimate DYNODE-P/5.2 computer model. These tests span a wide range of anticipated operational occurrences for Pressurized Water Reactors. In general, satisfactory agreement between calculation and measurement for the key system parameters (nuclear power, primary and secondary pressures, temperatures, liquid levels, and flows) have been found. Sensitivity studies have resolved all significant discrepancies. These analyses have provided a significant qualification of the model for application to these types of events.
