OSTI ID:7157246
Six experiments were conducted in the Semiscale Mod-3 system to investigate the effect of primary coolant pump operation on thermal-hydraulic behavior during a small break loss-of-coolant accident (LOCA). They were three cold leg break and three hot leg break experiments. The break size simulated was 2.5% (of cold leg pipe flow area), representing a circular opening in the side of a PWR pipe of approximately 11 cm. For each of the experiments, emergency core coolant (ECC) was injected into the cold legs at scaled flowrates corresponding to the availability of a single high pressure injection system train.
