| Title | Failure to Perform Appropriate Preventive Maintenance on Reactor Building Heating, Ventilation, and Air Conditioning Components |
| Description | A finding of very low safety significance with an associated non-cited violation of 10 CFR 50.65(a)(2) was self-revealed on November 24, 2013, for the licensees failure to demonstrate that the performance of the temperature switches, steam traps, and drains of the reactor building heating, ventilation, and air conditioning (RBHVAC) system were effectively controlled through appropriate preventive maintenance or monitored as specified in 10 CFR 50.65(a)(1), such that the RBHVAC system remained capable of performing its intended function. The lack of preventive maintenance on these components for the RBHVAC system led to its failure and resulted in a loss of the safety function of secondary containment. Corrective actions included the creation of work orders to replace the remaining steam traps and reclassification of the steam traps and drains as Non-Critical in the licensees preventive maintenance program with annual preventive maintenance activities for cleaning scheduled prior to the heating season. The finding was of more-than-minor significance since it was associated with the Structures, Systems, and Components and Barrier Performance attribute of the Barrier Integrity Cornerstone and adversely affected the cornerstone objective to provide reasonable assurance that physical design barriers protect the public from radionuclide releases caused by accidents or events. Specifically, inadequate preventive maintenance of the RBHVAC system components resulted in a trip of the system. Therefore, this performance deficiency had a direct effect on the licensees ability to maintain the safety function of secondary containment. The finding was a licensee performance deficiency of very low safety significance because it represented only a degradation of the radiological barrier function provided for the Reactor Building. This finding affected the cross-cutting area of problem identification and resolution and the cross-cutting aspect of trending (P.4). Specifically, over the past several years there were multiple trips of the RBHVAC system documented in the licensees corrective action program from failures of temperature switches, steam traps, and drains, including an event from January 22, 2013, that also resulted in a loss of the secondary containment function. The licensee failed to analyze this information in the aggregate to identify and correct the issue. |
