| Title | Inadvertent Operation of Plant Equipment |
| Description | A self-revealed finding of very low safety significance and associated non-citied violation of TS 5.4.1 occurred because the licensee failed to implement procedures for equipment control. Specifically, plant workers caused two unplanned Limiting Conditions for Operation (LCO) entries due to inadvertent equipment operation that resulted from inadequate implementation of procedures for equipment control. The first inadvertent equipment operation rendered the Unit 1 west motor driven auxiliary feedwater (AFW) pump inoperable for approximately 14 minutes; the second inadvertent equipment operation rendered one qualified offsite electrical circuit inoperable to both units for approximately 30 minutes. For corrective actions, in both cases, the licensee restored the equipment to an operable status and communicated the errors to site personnel to improve worker situational awareness. Using IMC 0612, Appendix B, the inspectors concluded that the issue was more than minor because it was associated with the equipment performance attribute of the Mitigating Systems Cornerstone and adversely impacted the cornerstone objective of ensuring the reliability of systems that respond to initiating events. The inspectors determined that the finding was of very low safety significance (Green) using IMC 0609, Exhibit 2, because the finding: was not a deficiency affecting the design or qualification of a mitigating system; did not represent a loss of system or function; did not represent a loss of function for greater than the technical specification allowed outage time; and did not represent an actual loss of function of one or more non-technical specification trains of equipment designated as high safety-significant. The inspectors concluded that the finding included an aspect in the Work Control component of the Human Performance cross-cutting area because the licensee failed to appropriately plan work using risk insights. |
