| Title | Failure to Construct Drywell Shielding According to Design Documents |
| Description | The inspectors identified a Green noncited violation of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, regarding the licensees failure to build a permanent drywell shielding system in accordance with the approved design documents. During a prestartup inspection of the drywell, inspectors discovered numerous assembly errors and unevaluated piping interactions with safety-related piping in the as-left configuration. This issue was entered into the licensees corrective action program as Condition Report CR-CNS-2008-05208. The finding is more than minor because it was associated with the design control attribute of the Mitigating Systems Cornerstone, and affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events. Using the Manual Chapter 0609, Appendix G, Shutdown Operations Significance Determination Process, flowchart, the inspectors determined that the finding is of very low safety significance because it did not result in the loss of any mitigation capability identified in the Manual Chapter 0609, Appendix G, Attachment 1, worksheet and that no qualitative risk assessment is required. The cause of this finding is related to the human performance crosscutting component of Work Practices because licensee personnel provided inadequate management oversight of contractors erecting permanent scaffolding in the drywell H.4(c) |
