Recorded test data are presented for Test S-07-8 of the Semiscale Mod-3 baseline test series. This test is one of several Semiscale Mod-3 experiments conducted to investigate the thermal and hydraulic phenomena accompanying a hypothesized loss-of-coolant accident in a pressurized water reactor (PWR) system. Test S-07-8 was conducted from initial conditions of 15.7 MPa and 556/sup 0/K to investigate the response of the Semiscale Mod-3 system to a blowdown transient following a simulated double-ended off-set shear of the broken loop cold leg piping. The specific objective of this test was to provide reference data to evaluate integral blowdown and reflood behavior during a 200% cold leg break with emergency core coolant (ECC) injection into the vessel lower plenum of the Mod-3 system.
