3. DESCRIPTION OF TEST FACILITY

Two Bundle Loop facility. Volume scaling ratio = 1:382. Height ratio = 1:1. The facilities include the following to simulate a BWR system: pressure vessel, main steam system, feedwater, recirculation, ECCS, ADS, break line, utility system, power supply and instrumentation system. The pressure vessel has two heated simulated fuel assemblies.

4. DESCRIPTION OF TEST

Small break in recirculation line. The break area and initial power were 3.4% DBA and 4 and 6 MW respectively. Single failure of the HPCS was assumed for the ECCS network and operation of LPCS plus 3LPCI plus ADS was simulated.
