Title | Inadequate Procedure for Reactor Vessel Head Lift |
Description | While performing a review in accordance with Operating Experience Smart Sample FY2007-03, Crane and Heavy Lift Inspection, Supplemental Guidance for Inspection Procedure 71111.20, the inspectors identified a noncited violation of Technical Specification 5.4.1, Procedures, associated with the licensees failure to ensure that adequate procedures were available for removal and reinstallation of the Unit 1 reactor vessel head. Specifically, Procedures OP-1504.007, Unit 1 Reactor Vessel Closure Head Removal and Storage, Revision 14; and OP-1504.009, Unit 1 Reactor Vessel Closure Head Installation, Revision 17, allowed the vessel closure head to be lifted to a height which exceeded the maximum analyzed height in the head drop analysis. This issue was entered into the licensee\'s corrective action program as Condition Report ANO-1-2008-1555. The finding was determined to be more than minor because it was associated with the procedure quality attribute of the initiating events cornerstone, and it directly affected the cornerstone objective to limit the likelihood of those events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. Using NRC Manual Chapter 0609, Significance Determination Process, Appendix G, Shutdown Operations Significance Determination Process, the inspectors determined that the finding was not a loss of shutdown control. The finding was further evaluated using Manual Chapter 0609, Appendix G, Attachment 1, Shutdown Operations Significance Determination Process Phase 1 Operational Checklists for Both PWRs and BWRs, Checklist 3. The finding was determined to have very low safety significance because the event did not: 1) affect core heat removal, 2) inventory control, 3) power availability guidelines, 4) containment control guidelines, and 5) reactivity guidelines. The finding had a crosscutting aspect in the area of Human Performance associated with Resources H.2(c), because the licensee failed to provide complete, accurate and up-to-date procedures and work packages for the removal and installation of the reactor vessel closure head |
