| Title | Licensee-Identified Violation |
| Description | 10 CFR Part 50, Appendix B, Criteria III, Design Control, states, in part, that measures shall be established to assure that regulatory requirements and the design basis for those components to which the appendix applies are correctly translated into procedures and instructions. Contrary to this, on March 11, 2009, the licensee identified in CR326432 missing design and licensing basis information for the EDG start-up air system. The associated OD 273 concluded the air compressor must be functional to support EDG operability. This design basis information was not translated into procedures NOP-DGM-001A/B and ARP-47091C/F that provided guidance for operability of EDG A and B. On November 3, 2010, CR402113 was written when two of the three fan belts on the EDG A air compressor were found broken. The CR concluded the air start compressor was non-functional, but the EDG A was declared operable based on the guidance in NOP-DGM-001A/B and ARP-47091C/F that the EDGs are operable when starting air header pressure is greater than 200 psig. Based on continued discussions with engineering, CR402113 was finally completed on November 16, 2010, and the licensee concluded that with the EDG A start-up air compressor non-functional, EDG A was inoperable. The inspectors answered no to the Mitigating Systems Cornerstone questions and screened the finding as having very low significance (Green) in accordance with IMC 0609, Significance Determination Process, Attachment 0609.04, Phase 1 Initial Screening and Characterization of Findings, Table 4a, dated January 10, 2008. The licensee evaluated this issue in CR402383 and CAs included changes to procedures NOP-DGM-001A/B and ARP-47091C/F to include functionality of the air start-up system and to review past operability of the EDGs based on EDG start-up air compressor functionality. |
