The inspectors identified a
NCV of Technical Specification (T.S.) 5.7.1 for failure to properly implement procedural requirements and engineering controls for materials brought into containment while the plant was at power. The procedural violation resulted in temporary equipment/material left in containment with incorrect/incomplete documentation. The licensee entered these issues into the corrective action program (
CAP) and either removed or properly evaluated the materials left in containment. This finding is more than minor because it was associated with the
Mitigating Systems Cornerstone attribute of equipment performance, specifically reliability, and adversely affected the cornerstone objective. The finding is of very low safety significance because no equipment was rendered
inoperable. The finding directly involved the cross-cutting area of human performance under the procedural compliance aspect of the work practices component, in that, the procedural requirements of the licensees procedure for containment access were not met and equipment/material left in containment was not properly analyzed and documented.
