| Title | Inadequate Testing Equipment Used for Alignment Verification of Emergencey Diesel Lube Oil Piping |
| Description | The inspectors identified a noncited violation for an inadequate control of measuring and test equipment used to verify the design basis of a safety-related system. On June 2, 2009, Wolf Creek measured pipe gaps and angles of deflection associated with Smith-Blair couplings on the emergency diesel generator lube oil and jacket water systems. Wolf Creek used commercial grade tape measures and protractors to determine whether the piping met vendor and design requirements or if the piping had to be refitted. Some of the measurements indicated little or no margin from the maximum pipe gap tolerances. This issue was entered into the corrective action program as Condition Report 00017781.Failure to use appropriately qualified measuring and test equipment when verifying the design specifications of a safety-related system was a performance deficiency. The inspectors determined that this finding was more than minor because it is associated with the design control attribute of the Mitigating Systems cornerstone and it affected the cornerstone objective to ensure the availability, reliability, and capability of mitigating systems. The inspectors evaluated the significance of this finding using Inspection Manual Chapter 0609.04, and determined the finding to be Green because it did not result in the loss of operability or functionality and was not affected by external events such as earthquakes or floods. Consequently, this finding was determined to be of very low safety significance (Green). The inspectors also determined that the cause of the finding had a crosscutting aspect in the human performance area associated with work controls because Wolf Creek failed to place adequate instructions into the work order to assure that the use of the proper measuring and test equipment requirements were specified. Wolf Creek did not appropriately plan work activities by incorporating job-site conditions that may impact human performance |
