6.0 CONCEPT OF OPERATIONS FOR RECOMMENDED APPROACH 6.1 Overview of Operations and Assumptions The recommended operation associated with the de-inventory of SNF and GTCC LLW at BRP will consist of loading canisters into a transportation cask at the BRP facility with subsequent truck transport of the material to a rail spur. Due to the complexity of these operations, the sequence of activities are divided into five separate tasks: 1) mobilization operations (procurement/lease and delivery of required equipment to the site); 2) operational readiness (training program development, operator training, dry run(s), and operational readiness review); 3) site operations (performance of W74 transfer operations from W150 to TS125 for offsite transports); 4) heavy haul road and rail transportation operations; and 5) demobilization operations of equipment and personnel from the BRP site. Based on the number of canisters to be shipped (i.e., seven canisters with SNF and one canister with GTCC LLW), the cost associated with fabrication of multiple casks, and the additional cost associated with multiple rail moves, a one cask rail shipment concept was selected for this shipping campaign. The FuelSolutions TS125 Transportation Cask SAR (WSNF-120) [15] (Chapters 7 and 8) and the FuelSolutions Storage System Final Safety Analyses Report (WSNF-220) [11] were used in the development of the transfer operation at the BRP site and also for the transportation cask inspection and handling operations. The following assumptions were used in planning this activity: 1) Transfer of the canister from the W150 storage cask to the TS125 transportation cask will be completed in a horizontal orientation Figure 6-1. 2) A single failure proof lifting equipment may be required for the loaded cask lifting operations on the premises of the Part 72 licensed site if the lifting operations have to be carried out beyond the safety basis of the Part 72 SAR. For the purposes of this report it is assumed that the Part 72 license addressed and evaluated the lifting operations of the cask and single failure proof lifting equipment will not be required. 3) The FuelSolutions transfer system equipment currently located at the BRP site and the FuelSolutions TS125 transportation cask will be used for this transfer. The transfer cask located at the BRP site will not be used however. This decision was based on the presence of FuelSolutions equipment already available at the site and the fact that the equipment system is designed to be compatible with other FuelSolutions components. It should be noted that the current transfer equipment located at the BRP site does not include the transfer trailer, skid, and skid positioning system. As such a modified skid positioning system is recommended to be designed, fabricated, and used to position the TS125 cask at the canister transfer area for docking the transportation cask to the W150 storage cask. The skid positioning system would be permanently attached or positioned at a location directly in front of the upender/downender on the canister transfer pad. The transportation cask, attached to the intermodal skid, would be set in place on the skid positioning system and secured to that system. The skid positioning system would have a hydraulic function
