| Title | Failure to Provide Maintenance Instructions for Installation of Fluorescent Light Fixtures |
| Description | Inspectors identified a violation of Technical Specification 5.4.1.a, which requires that the licensee establish, implement, and maintain the applicable procedures recommended in Regulatory Guide 1.33, Revision 2, Appendix A, February 1978. Paragraph 9.a of Appendix A requires, in part, that maintenance that can affect the performance of safety-related equipment be properly preplanned and performed in accordance with documented instructions. Contrary to the above, prior to March 2013, the licensee did not preplan and perform maintenance that could affect the performance of safety-related equipment in accordance with documented instructions. Specifically, the licensee failed to establish instructions to ensure that fluorescent light fixtures in both Unit 1 emergency diesel generator rooms were returned to their analyzed design configuration after maintenance was performed. The licensee documented the issue in Condition Reports CR-ANO-C-2013-0631 and CR-ANO-C-2013-0632. Inspectors concluded that the licensees failure to have work instructions to control the design configuration of fluorescent light fixtures, in the Unit 1 emergency diesel generator rooms, was a performance deficiency. The finding is more than minor because it is associated with the Mitigating System Cornerstone attribute of procedure quality and adversely affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences (i.e., core damage). Using Manual Chapter 0609, Attachment 4, Initial Characterization of Findings, and Appendix A, The Significance Determination Process for Findings at Power, the finding was screened against the mitigating systems cornerstone and determined to be of very low safety significance (Green) because the finding did not: (1) result in an actual loss of operability or functionality, (2) represent a loss of system and/or function, (3) represent an actual loss of function of a single train for greater than its technical specification allowed outage time, (4) represent an actual loss of function of one or more non-technical specification trains of equipment designated as high safetysignificant for greater than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> and (5) involve the loss or degradation of equipment or function specifically designed to mitigate a seismic, flooding or severe weather event. This finding did not have a cross-cutting aspect associated with it because the most significant contributor was not indicative of current performance. Specifically, the licensee had never established instructions to ensure that the fluorescent light fixtures were returned to their analyzed design configuration after maintenance was performed. |
