Initial Site-Specific De-Inventory Report for Big Rock Point Report No.: RPT-3014537-002
Cask Lifting Jacks: A set of lifting jacks are required for movement of the storage cask. The hydraulic jacking system is used to lift the storage cask to allow placement of the air pad set (see Figure 2-7) under the set. The air pad set allows movement of the cask to and from the transfer station, and on the ISFSI pad. A set of four hydraulic jacks is used, one placed under each of the four air inlets. While the air pad system is available on-site, it is not known if the necessary jacks are available. Skid positioning system: As a transfer trailer and a transfer skid are not available on-site, a skid positioning system will be needed to position the TS125 cask, on its intermodal skid, during canister transfer operations. It is envisioned that this equipment will be mounted to the ISFSI pad and will provide for positioning of the TS125 cask to ensure adequate alignment with the storage cask. This equipment will need to be designed and fabricated. Cranes: It is envisioned that a single mobile crane would be required for the transfer and loading operations. This crane would be used to lift the transportation cask, as well as to handle all the ancillary equipment. Assuming the impact limiters are installed onto the loaded TS125 transportation cask prior to lifting, a commercially available mobile crane will be sufficient. Impact limiters: The transportation cask will arrive with two impact limiters according to the requirements of the Safety Analysis Report (SAR). The impact limiters would be fabricated as part of the transport cask procurement and fabrication. Intermodal transportation cradle, cradle straps, and axial end restraints: An intermodal cradle and associated straps would need to be fabricated for the TS125 cask. These devices would be specific for the TS125 cask and do not currently exist. It is assumed that the same equipment would be used for both truck and rail transport. Personnel barrier: As required by the SAR, a personnel barrier would be placed around the loaded cask. The barrier, which attaches to the cradle, spans the distance between the impact limiters and matches the outer diameter of the impact limiters [15] . This device does not currently exist, so it would need to be designed and fabricated. There are no unique requirements that would present expected complications with the lead time and cost of obtaining personnel barriers. The overall transport weight and dimensions for each TS125 Transport Cask, including margins, is estimated to be: 320,000 pounds, 29 feet long, 12 feet wide, and 13 feet high (measured from the cradle base). It is important to note that the 144-inch load width, which is driven by the impact limiters, will exceed the 128-inch width limit imposed by the Association of American Railroads (AAR) for unrestricted interchange service. This will require more initial planning with the railroads and will exclude certain routes. More discussion on possible routes is contained in Section 3. Figure 2-17 shows a representation of a TS125 Transport Cask on an intermodal cradle secured to a 12-axle railcar, where the top and bottom images show the cask with and without the personal barrier installed.
