Pe~ Technical Specification Action Statement 3.7.11.a, a Special Report is required when fire barrier penetration seals are impaired for greater than seven {7) days. T~is report satisfies this requirement.

The subject fire barrier impairments were ini'tiated in support of design changes and other Salem Unit 1 outage activities. Normally, the planning of penetration impairments includes their repair within seven (7) days. However, to fully support the work identified in this report, the penetrations could not be repaired within seven (7) days.

on'March 17, 1992, two (2) fire barrier penetrations were imp~ired in support of Service Water System modifications. On April 7, 1992, ten (10) fire barrier penetrations were impaired also in support of Service Water System modifications. On April 8, 1992, five (5) fire barrier penetrations were impaired in support of Service Water System pipe replacement for the Auxiliary Building Room Coolers. These penetrations are located as follows:
