REFUELING OPERATIONS BASES l
MANIPULATOR CRANE (Continued) or fuel assembly, and 3) the core internals and pressure vessel are protected from excessive lifting force in the event they are inadvertently engaged during lifting operations.
3/4.9.7 SPENT FUEL STORAGE BUILDING - BRIDGE CRANE and SPENT FUEL CASK CRANE i
The restriction on movement of loads in excess of the nominal weight of a fuel and control rod assembly and associated handling tool over other fuel assemblies in the storage pool ensures that in the event this load is dropped
- 1) the activity release will be limited to that contained in a single fuel assembly, and 2) any possible distortion of fuel in the storage racks will not l
result in a critical array.
This assumption is consistent with the activity release assumed in the accident analyses.
The outdoor overhead gantry crane does not meet the design requirements for wire rope strength and fleet angle safety margins of reeving systems, therefore the ropes must be inspected to assure that they meet the require-ments of the standard specified in the surveillance.
Cold proof tests of the crane will be performed to demonstrate OPERABILITY.
It is permissible to operate the crane at temperatures less than the temperature at which it was proof tested, provided these operations take place at derated loads as stated in the action statement.
3/4.9.8 RESIDUAL HEAT REMOVA'. l'O COOLANT CIRCULATION The requirement that at 1+sst one residual heat removal loop be in operation ensures that 1) suft cient cooling capacity is available to remove decay heat and maintain the wata-in the reactor pressure vessel below 140 F as required during the REFUELING MODE, and 2) sufficient coolant circulation l
is maintained thru the react - : ore to minimize the effects of a boron dilution incident and preve-cron stratification.
The requirement to ha W loops OPERABLE when there is less than i
23 feet of water above the cressure vessel flange ensures that a l
single failure of the oper
'coe will not result in a complete loss of l
tne reactor vessel head removed and 23 feet of water above the
~ vessel flange, a large heat sink is available for core coo' event of a failure of the a
operating RHR loop, adecus 1 to initiate emergency procedures to cool the core.
