10 CFR 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, states, in part, that activities affecting quality shall be prescribed by documented instructions or procedures appropriate to the circumstances. Contrary to this, following the January 2, 2013 leak on the 2H
EDG, the licensee identified that in May 2010 licensee personnel failed to prescribe the installation of rubber expansion joints on the 2H
EDG with procedures or instructions appropriate to the circumstances. Specifically DC-NA-09-00170,
EDG Lube Oil S-Line Flexible Connection did not contain post design change testing instructions that verified that the design change did not create an unintended deficiency as required by CM-AA-DDC-301, Post Design Change Testing , Revision 1. The inspectors determined that this finding was of very low safety significance (Green) because the finding did not represent an actual loss of function of at least a single train for greater than its technical specification allowed outage time or two separate safety systems out-of-service for greater than its technical specification allowed outage time. The inspectors determined that the licensee correctly evaluated the finding and developed appropriate corrective action as documented in the licensees
CAP as CR501347.
