Engineering Analysis of Characterization Ramps and Platforms

The calculations in Appendix A and B determine the adequacy of the ramps and platforms to accomplish two tasks: (1) Core sampling using the modifications imposed by the use of a FDNW foundation at PFP; and (2) Core sampling within the 200E and 200W Tank Farms without the imposed modifications. The calculations in this document determined that the ramps and platforms are adequate for use with core sampling equipment when sampling either tank 241-2-361 or within 200E or 200W Tank Farms. When sampling tank 241-2-361 the modifications made by ECN 651132 must be implemented. These modifications are the addition of diagonal cross bracing on both the lateral and longitudinal sides. Also, a 1 1/4 inch tie rod must connect both bases of each longitudinal side
