(Continued)

If any penetration seal fire damper selected for inspection is found by surveillance requirements 4.14.D.l(d) in a condition which may compromise the operability of the penetration seal, the cause shall be evaluated.

If the cause is a failure to adhere to penetration seal procedures, or an identified phenomenon (e.g.,

physical interference), the cause shall be corrected and potentially affected seals inspected.

Otherwise, a visual inspection of an additional 10 percent, selection based on the nature of the degradation, shall be made.

This inspection process shal' antinue until a 10 percent sawple with no degradation is found.

2. Fire doors required to meet the provisions of 3.14.D.1 shall be verified operable by inspecting the closing mechanism and latches every 6 months *, and by verifying:

a.

The operability of the fire -

door supervision system for each electrically supervised fire door by performing a l

functional test every month, b.

That each locked-closed fire door is in the closed position every week.

c.

That each unlocked fire door without electrical supervision is in the closed position every day.

  • Fire door inspections requiring access to radiation areas may be deferred until the next refueling outage or shutdown initially expected to be of at least a 7-day duration.
