Amendment No.35
REFUELING OPERATIONS BASES 1
3/4.9.6 REFUELING MACHINE i
The OPERABILITY requirements for the refueling machine ensure that: -(1) the refueling machine will be used for movement of CEAs and fuel
- assemblies, (2) each hoist has sufficient load capacity to lift a CEA or fuel assembly, and (3) the core internals and pressure vessel are protected from l
excessive lifting force in the event they are inadvertently engaged during lifting operations.
3/4.9.7 CRANE TRAVEL - FUEL HAN0 LING BUILDING The restriction on movement of loads in excess of the nominal weight of a fuel assembly, CEA, and associated handling tool over other fuel assemblies in the spent fuel 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 result in a critical array.
This assumption is consistent with the activity release assumed in the safety analyses.
3/4.9.8 SHUTDOWN COOLING AND COOLANT CIRCULATION T5e requirement that at least one shutdown cooling train be in operation ensures that (1) sufficient cooling capacity is available to remove decay heat and maintain the water in the reactor pressure vessel below 140'F as required during the REFUELING MODE, and (2) sufficient coolant circulation is main-tained through the reactor core to minimize the effects of a boron dilution incident and prevent boron stratification.
The requirement to have two shutdown cooling trains OPERA 8LE when there is less than 23 feet of water above the reactor pressure vessel flange, ensures that a single' failure of the operating s,hutdown cooling train will not result in a complete loss of decay heat removk1 capability. When there is no irradiated fuel in the reactor pressure vessel, this is not a consideration and only one shutdown cooling train is required to be OPERABLE. With the reactor vessel head removed and 23 feet of water above the reactor pressure. vessel flange, a large heat sink is available for core cooling, thus in the event of a failure of the operating shutdown cooling train, adequate time is provided-to initiate
= emergency procedures to cool the core.
3/4.9.9 CONTAllmENT PURGE VALVE ISOLATION SYSTEM The OPERABILITY of this system ensures that the containment purge valves will be automatically isolated upon detection of high radiation levels within the containment. The OPERA 8ILITY of this system is required to restrict the
~ release of radioactive material'from the containment atmosphere to the environment.
