Title 10 CFR Part 50, Appendix B, CriterioTitle 10 CFR Part 50, Appendix B, Criterion V, requires, in part, that activities affecting quality be prescribed by instructions, procedures, and drawings appropriate to the circumstance. Contrary to the above, on March 29 and April 18, 2009, the licensee failed to have procedures appropriate to the circumstance to ensure that periodic maintenance on the D5 and D6 EDG ventilation dampers was performed. The finding was determined to be of very low safety significance, because the dampers did not cause the EDG to be inoperable for greater than the TS allowed time. This issue was documented in 49 Enclosure CAPs 1175563 and 1178658. Corrective actions for this issue included returning the ventilation dampers to service and implementing preventive maintenance procedures to address damper alignment issuescedures to address damper alignment issues  +
