| Title | Reactor Building Crane and Reactor Building Crane Support Structure/Superstructure Design Calculation Issue |
| Description | The inspectors determined that an unresolved item (URI) existed concerning the design calculations that demonstrate the design adequacy of the reactor building crane, reactor building crane support structure and reactor building superstructure.
The inspectors reviewed Calculation No. CN-23934, Reactor Building Crane for Enrico Fermi Atomic Power Plant No. 2 Bridge and Trolley Structural Calculations, dated March 8, 1973, Calculation No. 4.02.09, Reactor Building Superstructure Steel Girt and Column Framing Design, Volume I, Revision A, Calculation No. DC-6019, Assessment of the Interior Columns for the Reactor Building Steel Superstructure Including Crane Lifted Load, Volume IA, Revision 0, and Calculation No. 4.02.04, Superstructure Roof Framing Bracing System, Volume I, Revision A The inspectors were concerned that the reactor building crane and reactor building crane support structure/superstructure had been evaluated using acceptance criteria that were not contained within UFSAR Table 3.8-18, Loading Combinations for Steel Structures Elastic Design. Also, inspectors were concerned that the reactor building crane and reactor building crane support structure/superstructure had not been evaluated for the applied loads that were part of the design and licensing basis load cases/load combinations specified in UFSAR Table 3.8-18, Loading Combinations for Steel Structures Elastic Design. In response to the inspectors concern, the licensee initiated corrective action program documents related to the reactor building crane and reactor building crane support structure/superstructure. The licensee entered these items into their corrective action program (CAP) as the following condition assessment and resolution documents (CARD): 1.
