SUBJECT:

Special Report on Inoperability of Fire Barriers 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 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.

The nonfunctional 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.

During a site modification, fire barrier penetration seals 53-N-2 and 26-W-1 were rendered inoperable on June 2, 1989, and June 6, 1989, respectively. The penetration seals were breached to facilitate conduit installation required under the modification. Due to procurement delays associated with the acquisi-tion of seal material certification and technical information, the seals could not be restored to operability within seven days. Material delivery is expected within the next three weeks, and restoration of the seals is currently scheduled for completion by July 31, 1989.

l Fire barrier penetration seals 53-N-2 and 26-W-1 have been inoperable for greater than seven days, which exceeds the time limit of Technical Specifi-cation 2.19(7). The required compensatory measures (firewatches) of Technical Specification 2.19(7) have been in place for the entire time period in which 8907190065 890710 5 ADOCK 0500 gDR 4sse4 Empioumengn gu;;opponunau
