BEFUELING OPFJBTIONS BASES 3/4.9,6 CRANE AND 1101ST OPERABILITY 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 event they are inadvertently engaged during lifting operations.*
l 3/4.9.7 CRANE TRAVEL SPENT FUEL STORAGE POOL The restriction on movement of loads in excess of the weight specified provides some assurance that with the failure of the litting device the fuel pool would not-be dacaged to such.a degree that the irradiated fuel would-be subjected to a loss of-coolant.
3/4.9.8 and-3/4.9.9 WATER LEVEL RLACTOR VESSEL AND SPENT FUEL STORAGE POOL The restrictions on minimum water level ensure that sufficient water
- depth _ is available to remove 98% of the assumed 10% iodine gap activity released from-the rupture of. irradiated fuel assembly.
This minimum water
' depth is consiatent 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 l
control rod drives will be performed under conditions that limit the probability-of inadvertent criticality.- The requirements for simultaneous removal of more than one control rod are more stringent since the SUUTDOWN MARGIN specification provides for the core to remain suberitical with only one control rod' fully. withdrawn.
- - 'Dae fuel grappic' hoist overload cutoff demonstration load of 1600 pounds is based on the submerged fuel bundle loads of 650 pounds, the highest unloaded hoist cable-supporteo load of approximately 660 pounds,'and a tolerance for fuel bundle friction and load spikes of 290 pounds.
The. fuel grapple hoist loaded. interlock demonstration load of 750 pounds is 1 based on the highest unloaded hoist cable-suppo~ted load of approximately.
660 pounds ples a to16rance for load spikes of 90 pounds as sections are raised and lowered.

APPLICABILITY:
During movement of fuel assemblies or control rods within the reactor pressuro vessel.
