Title | Licensee-Identified Violation |
Description | Title 10 CFR 50.65(a)(1) requires, in part, that the licensee shall monitor the performance or condition of structures, systems, or components within the scope of the monitoring program as defined in 10 CFR 50.65 (b) against licenseeestablished goals, in a manner sufficient to provide reasonable assurance that such structures, systems, or components are capable of fulfilling their intended functions. Title 10 CFR 50.65(a)(2) states, in part, that monitoring as specified in 10 CFR 50.65(a)(1) is not required where it has been demonstrated that the performance or condition of a structure, system, or component is being effectively controlled through performance of appropriate preventive maintenance, such that the structure, system, or component remains capable of performing its intended function. Contrary to the above, the licensee failed to demonstrate that performance of the Unit 2 electrical auxiliary building ventilation system was being effectively controlled through the performance of appropriate preventive maintenance, in that after a repetitive maintenance preventable failure of the Unit 2 electrical auxiliary building ventilation Train B smoke purge inlet damper occurred on January 27, the licensee failed to consider placing the system under 10 CFR 50.65 (a)(1) for establishing goals and monitoring against the goals. Using the Significance Determination Process Phase 1 worksheets from Inspection Manual Chapter 0609, the inspectors determined that this violation had very low safety significance (Green) because it did not result in the actual loss of safety function of one or more trains and did not screen as risk-significant due to seismic, flooding, or severe weather. The licensee captured this violation in Condition Report 09-1508 |
