Docket No. 50-285 Gentimnen

==SUBJECT:==
Special Report on Inoperability of Fire Protection Equipment The Omaha Public Power District, holder of Operating License DPR-40, submits this special report pursuant to the requirements of Fort Calhoun Station Unit No. 1 Technical Specification 2.19, " Fire Protection Systems".
FortCalhounStationUnitNo.1Techr.icalSpecification2.19(7)requiresthat all penetration fire barriers protecting safety-related areas be functional (intact). With a penetration fire barrier non-functional, within one hour either establish a continuous fire watch on at least one side of the affected penetration, or verify the operability of fire detectors on at least one side of the penetration and establish an hourly fire watch patrol. The non-functional penetration must be restored to functional status within seven days, or, failing that, prepare and submit within an additional 30 days a report to the Nuclear Regulatory Commission pursuant to Technical Specification 5.9.3.
On February 11, 1991, both barrier penetration 19-E-39, between Room 19 and the Turbine Building, and the concrete block wall at the east end of Corridor 4 were breached to support long term maintenance on heat exchanger AC-1A. A decision was made to maintain the breaches for tne duratioa of the maintenance activities as,ociated with AC-1A due to the considerable amount of time (aparoximately one man-day) required to restore the barriers at the end of a wor ( week and remove them at the beginning of the subsequent work week.                               As a result, these barriers were not restored to functional status until March 6, 1991. Appropriate compensatory measures, as required by Technical Specification 2.19(7),wereinplaceforthedurationoftheimpairments.
