Thermal hydraulics of a feed-water pipe breakage with a back-pressure check valve

Conference ·
OSTI ID:5798014

The SOLA-LOOP computer code for transient, nonequilibrium, two-phase flows in networks has been coupled with a dynamic check valve model. Transient back-pressure check valve behavior and fluid dynamic effects in the form of the so called water-hammer are numerically simulated for a feed-water pipe breakage accident. Three tests from the Superheated Steam Reactor Safety Program Project (PHDR) carried out near Frankfurt, West Germany are analyzed, and the calculated transient back-pressure check valve behavior and fluid dynamics effects are found to be in excellent agreement with the experimentally measured data. 5 refs., 15 figs., 4 tabs.
