Shielded railway transporter system equipment design and operational features

The U.S. Department of Energy (DOE) Hanford Site at Richland, Washington requires a rail-mounted, shielded transfer system for on-site transfer of radioactively contaminated equipment in the T-Plant, U-Plant, B-Plant and PUREX canyon tunnel facilities. Some typical contaminated equipment are tanks (5-15 tons), reboiler bundles (7 tons), centrifuges (17 tons), moderators (13 tons), and pulse generators (5 tons). The Multipurpose Transfer Box (MTB) is designed and engineered to transport these pieces of equipment and meet specific design constraints for function, operation, and modified 10 CFR 71 normal and hypothetical accident conditions for transport. 8 figs
