| description = As stated in 10 CFR 50.36(d)(3), Surveillance Requirements, are requirements relating to testing that assure that the necessary quality of systems and components is maintained, that facility operation will be within safety limits, and that the LCOs will be met. Contrary to this requirement, on June 9, 2008, the licensee discovered that surveillance procedures did not verify the required position of some valves necessary for operability of the RHR 'A' system during monthly surveillance verification. In reviewing SVI-E12-T1182A, RHR 'A' LPCI Valve Lineup Verification and System Venting, Revision 8, licensee personnel determined that the valve positions for three valves were not checked during the surveillance. Specifically the RHR 'A' head spray isolation valve (LPCI injection), an unlocked valve, was not verified for a two-year period. The licensee immediately verified proper position of the three valves and revised the surveillance procedure. The issue was determined to be of very low safety significance because it was determined not to have resulted in an actual loss of system safety function. The licensee entered the issue into their CAP as CR 08-41467 | | description = As stated in 10 CFR 50.36(d)(3), Surveillance Requirements, are requirements relating to testing that assure that the necessary quality of systems and components is maintained, that facility operation will be within safety limits, and that the LCOs will be met.
