| Title | Licensee-Identified Violation |
| Description | Title of 10 CFR Part 50 Appendix B, Criterion V, Instructions, Procedures and Drawings, states, in part, that activities affecting quality shall be prescribed by documented instructions and shall be accomplished in accordance with those instructions. Section 5.4[2] of Procedure EN-OP-104, Operability Determinations, Revision 3, required operability evaluations to provide a technical basis for each item in the detailed problem statements per Step 5 of Attachment 9.5 of the procedure. Contrary to the above, on August 21, 2009 plant engineers failed to provide a technical basis for the operability determination they performed by not considering external events such as earthquakes, high winds and tornados when determining operability of the standby services ventilation system which was in a degraded condition. Operations accepted the initial operability provided by engineering but the subsequent shift manager required the design engineering to perform new evaluation taking into account external events. The new operability determination was performed and determined that the standby service water system remained operable. This issue was documented in the licensees corrective action program as condition report CR-GGN-2009-04302. This finding was of very low safety significance since it did not result in a loss of operability of the standby service water system. |
