[en] The report is a descriptive plan of tests for the Steam Generator Separate Effects Task of the Full-Length Emergency Cooling Heat Transfer for the Separate Effects and Systems Effects Test Program (FLECHT SEASET). These tests consist of a separate effects test to be conducted on the Full-Length Emergency Cooling Heat Transfer Systems Effects Test (FLECHT SET) phase B steam generator. This test is used to measure and to characterize the steam generator secondary side to primary side heat release under postulated inlet fluid conditions which apply during a hypothetical pressurized water reactor loss-of-coolant accident
