| Title | |
| Description | A self-revealing Green NCV of 10 CFR 50 Appendix B, Criterion XVI, was identified for the failure to correct a condition adverse to quality which led to main control room isolation damper 1-VS-MOD-103D being inoperable for approximately19 hours on September 21-22, 2009 (CR 349075). The actuator was repaired and is scheduled for replacement in 2010.The finding, associated with the performance attribute of the barrier integrity cornerstone, is more than minor because it adversely affected the cornerstone objective, as it relates to control room integrity, to provide reasonable assurance physical design barriers protect public health and safety. The finding, evaluated perMC-0609, Attachment 4, Phase 1 Initial Screening and Characterization of Findings, was determined to be of very low safety significance (Green) because it did not result in a loss of safety function or loss of a singe train of the control room isolation boundary for more than its allowed outage time. This finding has a crosscutting aspect in the area of human performance, resources, in that equipment and other resources were not made available to assure nuclear safety by minimizing preventative maintenance deferrals (H.2.a) |
