| Title | Failure to Follow Instructions in Painting Procedure while Painting on Safety-Related Equipment |
| Description | The inspectors reviewed a self-revealing non-cited violation of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, for the licensees failure to follow procedure PMC-002-007, Maintenance and Construction Painting, while performing work on emergency diesel generator A. Specifically, while conducting painting activities in the emergency diesel generator cubicle between June 2014 and October 2014, the licensee failed to ensure that painting activities would not have an adverse impact on the moving parts and surfaces of the emergency diesel generator. Consequently, emergency diesel generator A failed to operate properly during a surveillance test on March 2, 2015. Immediate corrective actions included replacing the cylinder 7R fuel injector and fuel injection pump. The licensee restored emergency diesel generator A to operable status on March 4, 2015. The licensee entered this issue into their corrective action program as CR-WF3-2015-02626. This finding was more than minor because it was associated with the human performance attribute of the Mitigating Systems cornerstone and adversely affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the licensee conducted painting on and around the emergency diesel generator in such a manner that paint was inadvertently deposited and remained in a location which caused the cylinder 7R fuel metering rod to jam at the full-fuel position, which ultimately caused emergency diesel generator A to fail its surveillance test on March 2, 2015, and be declared inoperable. Using NRC Inspection Manual Chapter 0609, Appendix A, Exhibit 2, Mitigating Systems Screening Questions, the inspectors determined that this finding was of very low safety significance (Green) because it did not represent a design or qualification deficiency, did not represent a loss of safety function for a single train for greater than its technical specification allowed outage time, and did not screen as potentially risk significant due to a seismic, flooding, or severe weather initiating event. This finding has a Field Presence cross-cutting aspect in the area of Human Performance in that the licensee failed to provide adequate supervisory and management oversight of work activities to ensure deviations from standards and expectations were corrected promptly. |
