| Title | Licensee-Identified Violation |
| Description | Title 10 CFR Part 50, Appendix B, Criterion VIII, Identification and Control of Materials, Parts, and Components, requires, in part, that measures shall be established for the identification and control of materials, parts, and components, including partially fabricated assemblies. These identification and control measures shall be designed to prevent the use of incorrect or defective material, parts, and components. Contrary to that requirement, on January 7, 2014, following planned work on the Unit 2, Train A Emergency Diesel Generator, the licensee identified that an incorrect component, a fuel oil pump with an alternate design, had been installed on multiple emergency diesel generators. The licensee entered the issue into the CAP as IR 1604977, 2A Diesel Generator Engine Driven Fuel Oil Pump Not Like For Like, reinstalled the original fuel oil pump, and performed an evaluation for the remaining diesel generators. The licensee identified that a new fuel oil pump being installed on the diesel generator was not similar to the fuel oil pump being removed. This discrepancy was identified by maintenance staff during a procedurally required assessment of the new fuel oil pump. An extent of condition review identified that the fuel oil pumps currently installed on the remaining diesels (Unit 1 Trains A and B; Unit 2 Train B) were like the new fuel oil pump. These pumps had been replaced previously as part of routine preventative maintenance activities. Post-identification reviews determined that the new fuel oil pumps with the alternate configuration would perform similarly to the original pumps and therefore would not adversely impact diesel generator operability. The inspectors determined that the failure to identify that the fuel oil pumps installed on Unit 1 Trains A and B; and Unit 2 Train B were not like for like was a performance deficiency. The inspectors determined that the performance deficiency was more than minor because it was similar to an example in IMC 0612, Appendix E, Examples of Minor Issues. Specifically, Work in Progress Findings, Example C, identified that an issue is not minor if an incorrect component is installed and the system is returned to service. Also, the inspectors screened the issue using IMC 0609, Appendix A, The Significance Determination Process for Findings at Power, Exhibit 2, Mitigating System Screening Questions and answered Yes to Question 1: If the finding is a deficiency affecting the design or qualification of a mitigating SSC, does the SSC maintain its operability or functionality? Therefore, the issue screened as Green. |
