| Title | Failure to establish adequate preventative maintenance for the safety related main control room air conditioning units |
| Description | A self revealing Green NCV (with two examples) of Hatch Unit 1 and Unit 2 TS 5.4, Procedures, was identified for failure to establish and perform preventive maintenance activities to replace the B main control room condensing unit overload in the MS2 motor starter components prior to age related failure of the component. The licensee entered this issue into their corrective action program as CR 195542. Failure to establish and perform preventive maintenance activities to replace aged B main control room condensing unit overload in the MS2 starter components prior to their failure is a performance deficiency. Specifically, section 5.4 of NMP-ES-006, Predictive Maintenance Implementation and Continuing Equipment Reliability Improvement , requires, in part, that the licensee develop and maintain a documented maintenance strategy with recommended time-based preventive maintenance taking into account OEM/Vendor recommendations and other data affecting component reliability. This performance deficiency is more than minor because it adversely affected the SSC and Barrier Performance attribute of the barrier integrity cornerstone objective to ensure physical design barriers protect the public from radionuclide releases caused by accidents or events. The inspectors evaluated the finding in accordance with IMC 0609, Attachment 4, Initial Characterization of Findings, using table 2 Cornerstones Affected by Degraded Condition or Programmatic Weakness. The finding affected the barriers cornerstone. Further evaluation was required using Appendix A, The Significance Determination Process (SDP) for Findings At-Power. Based on Appendix A, Exhibit 3 Barrier Integrity Screening Questions, the finding represented a degradation of the radiological barrier function provided for the control room, spent fuel pool, or SBGT system and therefore screened as Green. This finding has a cross-cutting aspect in the Operating Experience component of the Problem Identification and Resolution area because the licensee did not implement operating experience through changes to station procedures when prior age related failures were identified at the site |
