The inspectors identified a finding of ver … The inspectors identified a finding of very low safety significance and associated NCV of 10 CFR Part 50, Appendix B, Criterion III, Design Control, for the licensees failure to evaluate piping interactions between the service water (SW) and residual heat removal (RHR) systems. Specifically, the SW piping was observed to vibrate and an associated support clamp was oscillating very closely to another support clamp of a nearby RHR pipe. The loads of the potential impact between the clamps were not analyzed. This finding was entered into the licensees CAP to perform a formal evaluation of the condition to accept it as part of the design of the systems or to eliminate the condition. The performance deficiency was determined to be more than minor because it was associated with the Mitigating System Cornerstone attribute of equipment performance and adversely affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The finding screened as of very low safety significance (Green) because it was a design deficiency confirmed not to result in loss of operability. Specifically, the licensee performed an operability determination which concluded the affected pipe supports remained functional. The inspectors did not find an applicable cross-cutting aspect which represented the underlying cause of this performance deficiency; therefore, no cross-cutting aspect was assigned.ore, no cross-cutting aspect was assigned. +
