Cn Thursday, June 5, 1980 following an inspection of fire barriers protecting safety related areas, it was reported that several penetrations were found in a degraded condition.

Several conduit penetrations had not been sealed at the open end in the control room where wires entered the panels.

3)

A cable penetration of the C Battery Room was found not to be scaled.

7 An inspection of all areas of concern was completed at approxinately 1430 hours0.0166 days <br />0.397 hours <br />0.00236 weeks <br />5.44115e-4 months <br /> follo.ving the discovery.

Corrective Action

A fire watch of the areas of concern was conducted until all of the penetrations were repaired.

All penetrations found in a degraded condition were estooin3hed to their required condition. Those personnel involved with the failure to carry out the required fire watch were instructed as to the ir-portance of the fire watch and the net.essity to provide the information to succeeding shifts.

Inspec-tions of fire barriers are continuing.

Fire barriers found to have been pene-trated not satisfying the requirements of the Oyster Creek Fire Protection Pro-gram will be repaired as required.

Failure Data Not applicable.
