3. DESCRIPTION OF TEST FACILITY

The Leibstadt Nuclear Power Station is equipped with a direct cycle boiling water reactor belonging to the General Electric BWR product line BWR/6. The MARK III containment system encloses the nuclear island. The nuclear system is provided with a 238-inch internal diameter vessel and the core is built up of 648 fuel elements and 84 control rods. Each fuel bundle consists of 62 fuel rods and 2 water rods in an 8 x 8 array. The rated power of the Leibstadt BWR is 3012 MWt and it is designed for a net power of 942 MWe.

4. DESCRIPTION OF TEST

The purpose of the test STP-2001 which occurred on 15 October 1984 was to demonstrate the capability of the Reactor Core Isolation Cooling (RCIC) system to maintain the reactor water level above level 1 (-337 cm) following a total loss of feedwater with the HPCS system unavailable. The test was initiated by tripping the two operating feedwater pumps. The HPCS was prevented from initiating automatically.
