SPECIAL REPORT (SPR 920001)

This Special Report is being submitted by South Carolina Electric & Gas Company pursuant to the requirements of the Virgil C. Summer Nuclear Station (VCSNS) Station Administrative Procedure (SAP) 131A, Fire Eaainment/Systeml x Operability Requirements.

On January 28, 1992, during an engineering inspection of the Diesel Generator fire Service Sprinkler System, a piping penetration in a 3-hour rated fire wall separating the "A" and "B" Diesel Generator Rooms was identified as not listed in the required fire barrier Surveillance Test Procedure (SIP). The penetration was sealed, but because it was not listed in the applicable STP

(/28.027), no surveillance had been performed as required by SAP-131A. The penetration was declared inoperable and compensatory action was taken as required by procedure. ANonconformanceNotice(NCN)wasinitiated documenting the discrepancy. Disposition of the NCN directed that the penetration be inspected, reworked / repair (if required) to the original installation, and the penetration be included in the applicable STP.

Inspection of the penetration found it to be functional as is, and it was declared operable on January 31, 1992. A procedure change has been made to incorporate the penetration.

The cause of this event was the inadvertent omission of the barrier from the applicable SlP. SAP-131A Surveillance Requirement requires a visual inspection of at least 10 percent of each type of sealed penetration be performed at least once each 18 months. In the upcoming STP inspection, a 100 percent inspection of fire barriers will be performed. Each fire barrier will be verified and uniquely identified at this time. Any barrier not listed in the STP will be readily identified by the absence of a label or tag. This action will be completed by January 1994.
