Fort Calhoun Station Unit No. 1 Technical Specification Section 2.19(7) requires that all pe.'etration fire barriers protecting safety-related areas shallbefunctional(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 pM ml.

The non functional penetration must be restored to functional status t . in seven days, or, failing that, prepare and submit within an additional .,0 days a report to the Nuclear Regulatory Commission pursuant to Technical Specification 5.9.3.

On April 11, 1990 fire damper FD-88 was declared inoperable as a fire barrier to allow for routing of electrical cables to support outage modification work. This damper remained inoperable as a fire barrier for greater than 7 days due to the amount of work innlved in the modification. Fire damper FD-88 was declared operable on May 9, 1990. As required by Technical Specifications the necessary compensatory na sures were in place for the entire time period the fire damper was inoperable.

On April 23, 1990 fire door 1007-15 was discovered to be inoperable as a fire barrier due to structural damage and an inoperable lockset.
