Green . The NRC identified a non -cited violation (
NCV ) of the facilitys operating license for the failure to identify a non functional
fire barrier penetration and enter it into the corrective action program (
CAP) when the initial damage to the
fire barrier occurred. The licensee also failed to implement required compensatory measures for a nonfunctional
fire barrier penetration contrary to the approved fire protection report . The licensee entered the issues into their
CAP as Condition Report (CR) 1263322 . The performance deficiency was determined to be more than minor because it was associated with the protection against external events (fire) attribute of the
Mitigating Systems cornerstone and adversely affected the cornerstone objective in that there was no assurance the
fire barrier would prevent the spread of fire through the cable
penetration during a design basis fire. The finding was of very low safety significance (Green) due to fully functional automatic suppression systems on either side of the
fire barrier . T he inspectors identified a cross- cutting aspect in the identification component of the Problem Identification and Resolution area because the licensee failed to enter the damaged fire barrier into their
CAP after it was initially damaged . [P.1]
