10 CFR 50, Appendix B, Criterion V, Instruction Procedures and Drawings, required, in part, that activities affecting quality shall be prescribed by documented instructions, procedures or drawings, of a type appropriate to the circumstances. Contrary to the above, work order SNC556771 which was used to reinstall valve Q1E11HCV603B,
RHR Heat Exchanger Discharge Valve, on April 13, 2015, was not appropriate because it did not require proper valve linkage adjustment in the closed position as stated in the vendor manual. As a result, additional valve linkage adjustments were required which contributed to inoperability of the B train of
RHR while in Mode 6 during a Unit 1 refueling outage on April 26, 2015. This finding screened as very low safety significance (Green) in accordance with
IMC 0609, Appendix G, Attachment 1, Shutdown Operations Significant Determination Process Phase 1 Initial Screening and Characterization of Findings, issued May 9, 2014, because all of the screening questions were answered No. The valve was repaired and operability of the B train of
RHR was restored on April 28, 2015. This issue was entered into the licensees corrective action program (
CAP) as condition report (CR) 10061313.
