Dear Mr. Martin:
I-
Reference:
Docket No. 50-285 i
Special Report on Inoperability of Fire Barrier 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 Section 2.19, " Fire Protection System".
Fort Calhoun Station Unit No. 1 Technical Specification Section 2.19(7) requires that all penetration fire barriers protecting safety-related areas shall be functional (intact). With a penetration fire barrier nonfunctional, within one hour, either establish a continuous firewatch 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 firewatch patrol.
Restore the nonfunctional penetration to functional. status within seven days, or prepare and submit within an additional 30 days a report to the Nuclear Regulatory Commission. This report is being submitted pursuant to Technical Specification 5.9.3.
On November 17, 1985, the pyrocrete fire barrier separating fire areas 36A and 36B was found to be dan 61ed due to work on bus ducts in the immediate area. Maintenance Order uo, 857613 was issued to correct the nonconformi-ties. An hourly firewatch patrol was established for the fire areas affected.
As of December 16, 1985, not all of the repairs have been made due to man-power shortages and procurement difficulties.
The hourly firewatch patrol is still in effect and repair work is still in progress.
This report is being issued within the 30 day limit specified in Technical Specification 2.19(7); a followup repcrt will be issued within 30 days of completion of all repair work remaining.
