I PEPUELING OPERATIQ4S 3/4.9.6 CRAN 8 AND HOIST CPERABILITY LIMITING CONDITION FOR OPERATION 3.9.6 All crancs and hoists used for handling fuel assemblies or control rods within the reactor pressure vessel shall be OPERABLE.
6PPLICABILITY:
During movement of fuel assemblies or control rods within the reactor pressure vessel.
ACTION:
With the requirements for crane or hoist OPERABILITY not satisfied, suspend use of any inoperable crane or hoist from operations involving the movement of control rods and fuel assemblies after placing the load in a safe location, nrovisions of Specification 3.0.3 are nat applicable.
SURVEILI ANCE REQUIREMENTS 4,9.6 Each crane or hoist used for movement of control rods or fuel assemblies within the reactor pressure vessel shall be demonstrated OPERABLE within 7 days prior to the start of such operations with that crane or hoist by:
a.
Demonstrating operation of the overload cutoff when the load exceeds 1600 pounds for the mast fuel gripper and s 1050 pounds l
for all other crancs and hoists.
b.
Demonstrating operation of the loaded interlock when the load exceeds 750 pounds for the mast fuel gripper and s 350 pounds for l
all other cranes and hoists, c.
Demonstrating operation of the uptravel stop for all cranes and hoists other than the mast fuel gripper when uptravel would bring the top nf the active fuel to 7 feet below the normal spent fuel pool water level.
d.
Demonstrating operation of the slack cable cutoff when the load is less than 50 25 pounds for the mast fuel gripper.
e.
Performing a load test of at least 1000 pounds.

REFUELING OPERATIONS t
BASES 3/4.9 6 CPANE AND HOIST OPERABILITY The OPERABILITY requirements of the cranes and hoists used for movement of fuel assemblies ensures that:
- 1) each has sufficient iv.d 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 344.9.7 CRANE TRAVEL-SPFs FUEL STORAGE POOL The restriction on movement of loads in excess of the weight specified provices some assutance that with the failure of the lifting device the fuel pool would not be damaged to such a degree that the irradiated fuel would be subjected to a loss of-coolant.
344.9.8 and 3/4,9.9 VATER LEVEL-REACTOR VESSEL AND SPENT FUEL STORAGE POOL The restrictions on minimum water level ensure that sufficient water depth is available to remove 99% of the assumed 10%* iodine gap activi v released frun the rupture of irradiated fuel assembly.
This minimum wuter depth is consistent with the assumptions of the accident analysis, g
3/4.9.10 CONTROL ROD REMOVr.
This specification ensures ther 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 simultaneous removal of more than one control rod are more stringent since the SHUTDOWN MARGIN specification provides for the core to remain suberitical with only one control rod 'ully withdrawn.
- The fuel grapple hoist overload cutoff demonstration load of 1600 pounds is based on the submerged fuel bundle loads of 650 pounds, the highest unloaded hoist cable supported load of approximately 660 pounds, and a tolerance for fuel by '13 friction and load spikes of 290 pounds.
The fuel grapple hoist loaded interlock demonstration load of 750 pounds is based on the highest unloaded hoist cable-supported load of approximately 660 pounds plus a tolerance for load spikes of 90 pounds as sections are
-raised and lowered.
