| Title | Failure to Adequately Implement the Preventive Maintenance Program Procedure for a Service Water Pump Motor |
| Description | A self-revealing Green NCV of Technical Specification (TS) 5.4.1, Procedures, was identified for failure to modify an existing preventive maintenance (PM) task or schedule in accordance with CENG procedure CNG-AM-1.01-1018, Preventive Maintenance Program, Revision 00801. Specifically, CENG did not revise the PM for the B service water pump (SWP) motor despite having rewound the stator windings on the four other SWP motors after identifying poor manufacturing quality in the stator winding end turns of each of the motors. This resulted in the B SWP motor failing while in service on December 10, 2013. CENGs immediate corrective actions included replacing the failed motor with a refurbished spare and entering the issue into the corrective action program (CAP). Failure to modify an existing PM task in accordance with the PM program procedure was a performance deficiency within CENGs ability to foresee and correct and should have been prevented. Specifically, CENG did not adequately implement changes to the PM 3-year overhaul task or establish a revised schedule for which the SWP motors should be rewound. This ultimately resulted in the failure of the B SWP motor. This finding is more than minor because it is associated with the equipment performance attribute of the Mitigating Systems cornerstone and affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, due to the failure of the B SWP motor, the SWP was not operable or available until the motor was replaced. The inspectors evaluated the finding using Attachment 0609.04, Initial Characterization of Findings, worksheet to IMC 0609, Significance Determination Process (SDP). The attachment instructs the inspectors to utilize IMC 0609, Appendix A, Significance Determination Process for Findings At-Power. The inspectors determined this finding was not a deficiency affecting the design or qualification of a mitigating structure, system, and component (SSC), did not represent a loss of system and/or function, and did not represent an actual loss of function of at least a single train. Therefore, the inspectors determined this finding to be of very low safety significance (Green). In accordance with IMC 0612, the finding does not have a cross-cutting aspect, because the performance deficiency occurred between 2005 and 2008, would not likely occur today under similar circumstances, and is not reflective of present plant performance. |
