3. DESCRIPTION OF TEST FACILITY

The Semiscale Mod-1 system used for this test consisted of a pressure vessel with internals, including a 40-rod core with 36 electrically heated rods; an intact loop with steam generator, pump, and pressurizer; a broken loop with simulated steam generator, simulated pump, simulated reflood bypass lines, LOFT counterpart nozzles, and two rupture assemblies; a coolant injection accumulator for the intact loop; high and low pressure suppression tank, header, and heated steam supply system.

4. DESCRIPTION OF TEST

Test S-06-2 was conducted to investigate the thermal and hydraulic phenomena accompanying a hypothesized loss-of- coolant accident in a pressurized water reactor (PWR) system. Initial conditions were 15513 kPa and 563K to investigate the response of the Semiscale Mod-1 system to a depressurization and reflood transient following a simulated double-ended offset shear of the broken loop cold leg piping. During the test, cooling water was injected into the cold leg of the intact loop to simulate emergency core coolant injection in a PWR. The heater rods in the electrically heated core were operated at an axial peak power density which was 50% of the maximum peak power density (52.5 kW/m).
