PARET-ANL Modeling of a SPERT-IV Experiment under Different Departure from Nucleate Boiling Correlations

This study presents numerical modeling of the SPERT-IV D-12/25 tests, a series of reactivity insertion, self-limiting, transients for a variety of coolant flow conditions. The PARET-ANL code is used to simulate the system response under these reactivity-initiated accident conditions and estimate the measured damage-indicating parameters-including the cladding temperature-using three departure from nucleate boiling (DNB) correlations, namely, …
