On February 6, 2008 at 1920 hours, Cook Nu … On February 6, 2008 at 1920 hours, Cook Nuclear Plant Engineering personnel identified an unanalyzed condition that has the potential to degrade plant safety. Specifically, a cable routing error in the original design for safety related Train 'A' 250 VDC was discovered. A short section of Train 'A' 250 VDC was found to pass through the Train 'B' 4kV switchgear room. This routing was discovered to exist in both units. The routing of the cabling presents the possibility that a fire could disable the remote control to both 4kV switchgear trains.</br>Local inspection identified no additional or supplementary fire barrier such as fire retardant wrapping.</br>Compensatory measures (fire watch) have been established.</br>In accordance with 10 CFR 50.72(b)(3)(ii) this condition is reportable as a condition that resulted in the nuclear power plant being in an unanalyzed condition that significantly degrades plant safety.</br>The licensee notified the NRC Resident Inspector.ensee notified the NRC Resident Inspector. +
