| Title | Licensee-Identified Violation |
| Description | Title 10 CFR 50, Appendix B, Criterion III, Design Control states in part that the design control measures shall provide for verifying and checking adequacy of the design, such as by design review. The FHB crane was designed to Seismic Category I requirements. The licensee used compliance with ASME NOG-1-2004 as the basis for its upgrade to single failure proof. Section 4153.6 of ASME NOG-1- 2004 describes the required boundary conditions to be used in the crane analysis. Contrary to above, on July 7, 2009, in Calculation 36272-17, Revision 11, the licensees design control measures failed to verify that the boundary conditions as required by ASME NOG-1-2004 were applied in the evaluation. Specifically, 33 Enclosure determination of seismic loads based on coefficient of friction was not consistent with the required crane boundary conditions per Section 4153.6 of ASME NOG-1-2004. This violation was of very low safety significance because the crane was not yet in operation as a single failure proof crane. The inspectors reviewed the revised calculation. The licensee entered this issue into its corrective action program (IR 966184). This licensee-identified violation closes URIs 005000454/2009004-04;05000455/2009004-04. |
