DESCRIPTION OF TEST FACILITY - ROSA-III is a 1/124 scaled down test facility with electrically heated core designed to study the response of engineered safety features to loss-of-coolant accidents in in commercial BWR. It consists of the following, fully instrumented subsystems: 4.
DESCRIPTION OF TEST - Run 916 was a 50% split break test at the recirculation pump suction line. A failure of the HPCS diesel generator was assumed. At 190 seconds after the break, a peak cladding temperature of 917 K was reached during the reflooding phase. The full core could be effectively quenched by ECCS. 5.
EXPERIMENTAL LIMITATIONS OR SHORTCOMINGS - 6.
PHENOMENA TESTED - Core thermal hydraulics; parallel channel effects and instabilities; void collapse and temperature distribution during pressurization; critical power ratio. 7.
SPECIAL FEATURES OF EXPERIMENT - 8.
COUNTERPART EXPERIMENTS - ROSA-III run 926, which was a 200% double-ended break test. 9.
