Assessment of Subchannel Code ASSERT-PV for Flow-Distribution Predictions Available to Purchase

The recently released ASSERT-PV 3.2 code version provides improvements in the predictions of flow distribution, critical heat flux (CHF) and dryout power, and post-dryout (PDO) fuel sheath temperatures. This paper summarizes the flow distribution prediction improvements achieved with the new code version, by comparing code predictions against subchannel measurements from four experiments.
