DUKE POWER COMPANY OCONEE NUCLEAR STATION UNIT 3 Report Number: R0-287/82-05 Report Date: April 13, 1982 Occurrence Date: March 30, 1982 Facility: Oconee Unit 3, Seneca, South Carolina Identification of Occurrence: The Spent Fuel Pool Ventilation Fans were not operable during movement of fuel.

Conditions Prior to Occurrence: 40% FP Description of Occurrence: During the period between March 23 and March 29, 1982, ten fuel assemblies were moved in the Spent Fual Pool. On March 30, 1982, the Spent Fuel Ventilation Fans were found to be inoperable due to the control power having been " white tagged" for maintenance on March 23, 1982. This constitutes a violation of Technical Specification 3.8.12.b.

Apparent Cause of Occurrence: The apparent cause of this occurrence is a personnel error, in that the White Tags for the Spent Fuel Pool Fans were not properly placed or removed during performance of'a Penetration Leak Rate Test procedure.

Analysis u' Occurrence: Ten fuel assemblies were moved with the Spent Fuel Pool Ventilation System Fans inoperable. The offsite doses for the fuel handling accident without the fans in operation are within the 10 CFR 100 limits; thus, the health and safety of the public were not affected by this incident.

Corrective Action: The immediate corrective action was to properly clear the White Tags and shut the control power breaker for the Spent Fuel Pool Exhaust Fans which returned the fans to operable status.

The individuals involved have been counseled to ensure that a procedural step is completed before signing it off, and to ensure that White Tags are properly placed and removed.

An evaluation will be performed to determine what equipment should be tagged out to prevent the movement of fuel when the Spent Fuel Pool Exhaust Fans are tagged out. The results will be incorporated into all appropriate pro-cedures of all Groups.

The appropriate procedures will be modified to state specifically what equip-ment should be tagged when the Spent Fuel Pool Fans or associated circuits are tagged out.
