Preparation for Refueling The inspector verified that station refueling procedures contained
bot' functional and administrative controls governing new fuel
'
receipt and inspection, fuel transfer and core verification, fuel
sipping operations, and recycled fuel inspections. He also verified
.,
that the new fuel was received and inspected' in accordance with the
!
licensee's procedures.
The inspector reviewed the following procedures:

3.
Pre-fuel Handling Activities The inspector verified that surveillance testing involving technical specifications requirements, refueling machine operation, fue l storage area ventilation, refueling interlocks, crane testing, refuel-ing deck radiation monitors, and communication systems had been com-pleted prior to fuel movement in the vicinity of the reactor.
'
No items of noncompliance or deviations were identified.

4.
Fuel Handline Activities The inspector observed activities on the refueling deck and in the control room during both the day and evening shif ts to verify that refueling operations were being conducted in accordance with techni-cal specifications and approved procedures. He specifically audited core monitoring, containment integrity, fuel insertion and removal, fuel accountability, core internals storage, refueling deck house-keeping, vessel water level, reactor mode switch position, and control blade checks. He also verified that the individual directing fuel handling activities holds a senior operator license and was present directly supervising fuel handlers when work was being done that could affect core reactivity and that a licensed operator was present in the control room and in constant direct communications with a member of the fuel handling crew when work was being done that coul'd affect core reactivity.

The inspector noted that the cleanliness of the area around the refueling canal deteriorated as the refueling activities progressed.
The licensee took immediate corrective action to return the area to an appropriately clean condition.
No items of noncompliance or deviations were identified.
