| Title | Failure to Adequately Implement Procedural Requirements for Open Doors, Hatches, and Floor Plugs |
| Description | A self-revealing noncited violation of Technical Specification 5.4.1.a, \"Procedures,\" was identified for the failure of maintenance personnel to adequately implement procedural guidance. Specifically, on May 9, 2008, maintenance personnel failed to ensure the permit requirements of Procedure 0DP-9ZZ17, \"Control of Doors, Hatches, and Floor Plugs,\" were complete while accessing the tendon gallery access shaft, resulting in the control room determining that both trains of the pump room exhaust air cleanup system had been inoperable. This issue was entered into the licensee\'s corrective action program as Palo Verde Action Request 3172712 and as significant Condition Report/Disposition Request 3173930. The finding is greater than minor because it is associated with the barrier performance attribute associated with maintaining radiological barrier functionality for the auxiliary building and affects the cornerstone objective to provide reasonable assurance that the physical design barriers protect the public from radio nuclide releases caused by accidents or events. Using Manual Chapter 0609.04, \"Phase 1 Initial Screening and Characterization of Findings,\" the finding is determined to have very low safety significance because it only affected the barrier integrity cornerstone and only represented a degradation of the radiological barrier function of the auxiliary building. This finding has a crosscutting aspect in the area of human performance associated with work practices because the licensee did not ensure supervisory and management oversight of work activities, including contractors, such that nuclear safety is supported H.4(c) (Section 40A3) |
