Appendix B, Criterion V in
10 CFR Part 50 requires, in part, that activities affecting quality shall be prescribed by documented procedures and shall be accomplished in accordance with the procedures. Surveillance test procedures were prescribed to verify operability during post maintenance testing after fire protection system
carbon dioxide valves were replaced. Contrary to the above, in March 2009, the licensee failed to implement the prescribed surveillance test procedures for post maintenance testing after fire protection system
carbon dioxide valves 2-FCO-102, Unit 2 Reactor Cable Tunnel Quad 4, 2-FCO-106, Unit 2 Reactor Cable Tunnel Quad 1 and 1-FCO-104, Unit 1 Reactor Cable Tunnel Quad 3 South were replaced. All three valves were subsequently tested satisfactorily in May 2009 using the prescribed surveillance test procedures. The licensee entered this violation into its corrective action program as
AR 00851462,
Carbon Dioxide Valves Replaced without Proper Post Maintenance Testing. This violation was of very low safety significance because all three valves subsequently tested satisfactorily when the prescribed test procedures were performed
