The column K-301 at base is fixed along the Global X-axis, to determine the maximum moment acting on the connection (if connection is considered fixed) and to determine the forces at which the anchor bolt will yield to behave as pin connection as discussed in the attachment 6.
A modification to the boundary condition of connection (fixed to pinned) is required to eliminate the excessive loading (as discussed in Calculation S09-0036). The computer model in calculation S09-0036 at joint 6101 (Ref. 7) has a pin boundary condition to reflect this issue.
The pin boundary condition representation of the support is the worst case depiction of the connection behavior (more conservative for whole structure) considering that the existing anchor bolts are not present and joint is free to rotate. Hence, the results obtained for design purposes tend to be more conservative compared to when a fixed connection or semi-rigid connection is considered in the analysis.

4.1.3). The purpose of this calculation is to verify/evaluate the existing connections for Auxiliary Building (AB) Overhead Crane support steel structure, crane brackets, crane stops, crane rails and column base connections. This calculation also addresses the qualification of modified structural connections.

All of the Auxiliary Building steel structure connections are structurally acceptable and meet the necessary code requirements listed in Design Criteria Document (Ref. 4.5.3).
Table below shows the summary of modifications required to the Auxiliary Building steel structure as a result of Overhead Crane (FHCR-5) replacement.

3.0 INTRODUCTION
Progress Energy Crystal River Unit 3 (CR3) is implementing the Independent Spent Fuel Storage Installation (ISFSI) for Dry Fuel Storage campaign. The Transfer Casks (TC) containing the Dry Shield Canisters (DSCs) are placed into and removed from the Spent Fuel Pool (SFP) using the AB Overhead Crane (FHCR-5). The existing overhead crane capacity (120 tons but has subsequently been derated by 40% to 72 tons, and recently derated further to 25 tons per reference 4.1.4) is inadequate to handle the proposed TC to be used at CR3. In addition, the existing overhead crane does not meet the single-failure-proof criteria of NUREG 0554 (Ref. 4.2.5) and NUREG 0612 (Ref.
4.2.6). Therefore, the overhead crane must be upgraded to increase load capacity to 130 tons/15 tons, main and aux hook capacities. The existing crane is not modified. Instead, complete new crane, including the crane bridge structure as well as the trolley, is provided by the crane vendor.
Therefore, the Auxiliary Building is evaluated with the new crane loads along with other loads (e.g.,
dead loads, live loads, earthquake loads and wind loads).
The existing Auxiliary Building is designed to resist Operating Basis Earthquake (OBE) seismic loads and a design wind speed of 110 mph (Refs. 4.1.2, 4.4.1 and 4.4.6). This calculation and structural member evaluation calculation S09-0036 (Ref. 4.4.5) together demonstrate that the modified crane support structure can accommodate an upgraded single-failure-proof crane under heavy load cask handling to 130 tons capacity in conjunction with the loads defined by the original plant licensing basis and ASME NOG-1 (Ref. 4.2.1). This calculation and the Design Criteria Document (Ref. 4.5.3) describe the load combinations, analysis methodology, and acceptance criteria. The intent of this calculation is to use the identified critical loads from calculation S09-0036 (Ref. 4.4.5) for the design/evaluation of the member connections, column base connections, crane brackets, crane stops, crane rails and rail splice joints. The interface point between ENERCON and crane vendor is at the top of the runway rail where crane and supporting structure meet.
ENERCON is responsible for the structure below the interface, i.e., the supporting structure and crane vendor is responsible for above the interface, i.e., the crane bridge.

There is no open assumption in this calculation which requires later verification 6.0 DESIGN INPUT 6.1 Design Load GTSTRUDL force output results are documented in Attachment 7, 8 and 10 of calculation S09-0036 (Ref. 4.4.5) and shall be used as new design forces for the evaluation. Existing connection forces are taken from the steel structural drawings (Ref. 4.3.1 to 4.3.5). Existing connection type is determined using the shop drawings (Ref. 4.3.6 to 4.3.12).
Any additional design inputs required for the evaluation are addressed along the body of each Attachment.
Calculation No. S10-0063 Page 6 Revision 0 7.0 METHODOLOGY An analysis model for the Auxiliary Building has been developed using GTSTRUDL. The forces generated from the GTSTRUDL model have been compared to the original design forces developed by Gilbert Associates (Ref. 4.4.1 to 4.4.4). Any member connections that have new forces exceeding the original forces, have been evaluated, and modified where necessary.
The evaluation and modification of the existing member connections have been analyzed and designed according to the requirements set forth in the 6th edition of the AISC Manual of Steel Construction (Ref. 4.2.2).
Per Section 1.5.6 of AISC 6th edition, the allowable stresses were increased by one third when the design forces were produced from load combinations involving wind or seismic.
There are two exceptions to using the AISC 6th edition. The first occurs when analyzing or designing a connection for prying action. Because the AISC 6th edition does not address prying action, the 9th edition of AISC (Ref. 4.2.4) was used for prying action.
The other exception involves different types of bolts being offered today, versus what was offered when the AISC 6th edition was written. The AISC 6th edition offers high strength bolt types of A325 and A354 Gr. BC. Because AISC has replaced type A354 Gr. BC bolts with type A490 bolts, type A490 bolts were used for connection modifications when necessary. The A490 bolt allowable stress values were taken from the AISC 9th edition (Ref. 4.2.4).
See Attachment 1, 2, 3, 4, 6 and 7, Methodology section for any additional methodology to perform an evaluation of Moment Connection, Vertical and Horizontal Bracing Connection, Beam Shear/Axial Connection, Crane Connection, and Column Base Connection.
