i REFUELING OPEP.ATIONS BASES 3/4.9.6 CRANE AND HOIST OPERABILITT i
The OPERABILITY requirements of the cranes and hoists used for movement of fuel assemblies ensures that:
- 1) each has sufficient load capacity to lift a fuel element, and 2) the core internals and pressure vessel are protected from excessive lifting force in the evznt they are inadvertently engaged duringliftingoperations.if 3/4.9.7 CRANE TRAVEL-SPENT FUEL OTORAGE POOL The restriction on movement of loads in excess of the weight specified provides some assurance that with the f ailure of the lif ting device the f uel pool would not be damaged to such a degree that the irradiated fuel would be i
subjected to a loss-of-coolant.
3/4.9.8 and 3/4.9.9 WATER LEVEL-REACTOR VESSEL AND SPENT FUEL STORAGE POOL i
The restrictions on minimum water level ensure that uuf ficient water depth is availabic to remove 98% of the assumed 101 iodine gap activity i
released f rom the rupture of irradiated fuel assembly.
This minimum water depth is consistent with the assumptions of the accident analysis.
3/4.9.10 CONTROL ROD REMOVAL This specification ensures that maintenance or repair on control rods or control rod drives will be performed under conditions that limit the probability of inadvertent criticality. The requirements for simultaneoes removal cf more than one control rod are more stringent since the SHUTDOWN HARGIN specification provides for the core to remain subcritical with only one control rod fully withdrawn.
