| Title | Failure to Establish a Preventive Maintenance Procedure for Safety -Related Equipment |
| Description | The team identified a Green, non -cited violation of Technical Specification (TS) 5.4.1, which states , in part , Written procedures shall be established, implemented, and maintained covering the following activities , referenced in Regulatory Guide (RG) 1.33, Revision 2, dated February 1978, Appendix A.9 , Procedures for Performing Maintenance, which requires that maintenance that can affect the performance of safety -related equipment should be properly pre- planned and performed in accordance with written procedures, documented instructions, or drawings appropriate to the circumstance. Specifically, prior to September 29, 2017, the licensee did not have a procedure to implement maintenance as recommended by the vendor in Vendor Document VM460000161, ELMA Cast Coil Power Transformers Installation, Maintenance, Operating, and Storage Instructions. In response to this issue, the licensee performed testing to ensure that the transformer will perform its design function and is developing an improved maintenance procedure. The finding was entered into the corrective action program as Condition Report CR- GGN -2017- 09390. The team determined that the failure to implement vendor recommended preventive maintenance is a performance deficiency. The finding was more than minor because it was associated with the equipment performance attribute of the Mitigating Systems Cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the failure to have procedures that implement vendor recommended maintenance resulted in a question regarding the functionality of the transformer at elevated temperature. In accordance with Inspection Manual Chapter 0609, Appendix A, The Significance Determination Process (SDP) for Findings At -Power, dated July 19, 2012, the finding screened as having very low safety significance (Green) because it was a design or qualification deficiency that did not represent a loss of operability or functionality; did not represent an actual loss of safety function of the system or train; did not result in the loss of one or more trains of non- technical specification equipment; and did not screen as potentially risk -significant due to seismic, flooding, or severe weather. This finding had a cross -cutting aspect in the area of human performance associated with conservative bias because the licensee failed to ensure that maintenance implement a process of planning, controlling, and executing work activities such that nuclear safety is the overriding priority [H.5]. |
