Special Report on Inoperability of Fire Protection Equipment The Omaha Public Power District (0 PPD), holder of Onerating License DPR-40, submits this report pursuant to the requirements of Fort Calhoun Station (FCS)

Unit No. 1 Technical Specification (TS) 2.19, " Fire Protection Systems".

FCSTechnicalSpecificationSection2.19(7)requiresthatallpenetrationfire barriersprotectingsafety-relatedareasshallbefunctional(intact). With a penetration fire barrier non-functional, within one hour, either a continuous fire watch is to be established on at least one side of the affected penetration, or the operability of fire detectors on at least one siae of the penetration is to be verified and an hourly fire watch patrol established. The non-functional penetration must be restored to functional status within seven days or, failing that, a report to the Nuclear Regulatory Commission pursuant to TS 5.9.3 is to be pei,ared and submitted within an additional 30 days.

On January 30, 1992, two previously unidentified conduit penetrations were identified in the east wall of Room 81, which separates Room 81 from the Turbine Building. These conduit penetrations are sealed with grout and are considered to be correctly installed, however, no installation documentation was readily available to verify this. The penetrations were conservatively declared inoperableandappropriatecompensatorymeasures,asrequiredbyTS2.19(7),were instituted. The required compensatory measures will remain in place until installation documentation is found or an ins)ection is performed to verify adequate installation. This impairment will >e restored by the end of the 1992 Refueling Outage.
