3. 8. REFUELING OPERATIONS C.gontd) g. During reactor vessel head removal and while refueling operations are being performed in the reactor, the refueling boron tion shall be maintained in the primary coolant system and shall be checked by sampling on each shift. h. Direct communication between personnel in the control room and at the refueling machine shall be available whenever changes in core geometry are taking place. 3. 8. 2 If any of the conditions in 3 .'8 .1 are not met, all refueling operations shall cease immediately, work shall be initiated to satisfy the required conditions and no operations that may change the reactivity of the core shall be made. 3.8.3 Refueling operation shall not be initiated before the reactor core has decayed for a minimum of 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> if the reactor has been operated at power levels in excess of 2% rated power. j.8.4 The ventilation system and charcoal filter in the fuel storage building shall*be operating whenever irradiated fuel which has decayed less than 30 days is being handled by either. of the following operations:.
a. Refueling operation with the equipment door open, or b. Fuel handling in the fuel storage building.

If both fans are unavailable, any fuel movements in progress shall be completed and further fuel movements over the spent fuel storage pool shall be terminated until one fan is returned to service. 3.8.5 When spent fuel which has decayed less than one year is placed in the tilt pit storage racks, the bulk water temperature in the tilt pit storage area must be monitored continuously to assure that the water temperature does not exceed 150°F. Monitoring will continue for 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> after any addition of fuel to the main pool or the tilt pit or when a failure of the spent fuel pool cooling system occurs. Basis The equipment and general procedures to be utilized during refueling are discussed in the FSAR. Detailed instructions, the above tions, and the design of the fuel handling equipment incorporating built-in.interlQcks .and. safety features provide assurance that no incident could occur during. the refueling operations that would result in a hazard to public health and safety.(1)

Whenever changes are not being made in core geometry, one flux monitor is sufficient.

3. 13 __ CONTAINMENT BUILDING AND FUEL STORAGE BUILDING CRANES Applicability Applies to the use of _cranes over the primary coolant system and the spent fuel storage pool. Objective To specify restrictirins on the use of the overhead cranes in the tainment Building and the Fuel Storage Building.

Specifications

a. The containment polar crane shall not be used to transport loads -over the primary coolant system if the temperature of the coolant or steam in the pressurizer exceeds 225°F. b. The fuel storpge building crane shall not be used to move material past the fuel storage pool unless the crane interlocks are operable or they are bypassed and the crane is under administrative control of a supervisor.
c. The fuel storage building ventilation shall be operating and discharging through the HEPA and charcoal adsorbers during crane operation with loads in excess of 1300'pounds over the fuel storage pool when irradiated fuel which has decayed less than 90 days is in the spent fuel storage pool. If both fans are inoperable, any crane operations shall be completed and further crane operation with loads in excess of 1300 pounds over the spent fuel storage pool shall be terminated until one fan is returned to service. Basis Loads are not to be allowed over the pressurized primary coolant system to preclude dropping objects which could rupture-the boundary of the primary coolant system allowing loss of coolant and overheating of the core. (1) The fuel storage building crane is provided with a system of trolley and bridge electrical interlocks that will normally prevent trolley from moving over the storage pool.(2) This minimizes the possibility of dropping an object on the irradiated fuel stored in the pool and resulting in the release of radioactive products.

The interlocks may --be -bypassed under strict administrative control .to allow required movement of fuel and material over and to the east of the pool. The crane can be used over the equipment hatches located in the north and south ends of the Fuel Storage Building without the interlocks operable since a load, even if dropped) could not fall into the storage pool. nu0482-0296c-43-142 3-69 Proposed I -
