5 B-Cell is currently being cleaned out (i.e., removal of equipment, fixtures and residual radioactive materials) and deactivated. TPA Milestone M dictates that all mixed waste and equipment be removed from B-Cell by 5/31/99. The following sections describe the major activities that remain for completion of the TPA milestone. Size Reduce Tank 119 and Misc. Eauiment This activity is the restart of hotwork in B-Cell to size reduce the remainder of Tank 119 and other misc. pieces of equipment into sizes that can be loaded into a grout container. This activity also includes the process of preparing the containers for shipment from the cell. The specific activities and procedures used are detailed in Table 1. Load and ShiD Low-Level Waste This activity covers the process of taking a grouted LLW container from B-Cell and loading it into the 3-82B cask in the REC airlock and Cask Handling Area (CHA) for shipment to the LLBG. The detailed activities and procedures for this part of cell cleanout are included in Table 2. Remove and Size Reduce the 1 B Rack The next phase of cell cleanout is the removal of the 1 B rack from the cell. This includes the remaining activities to remove the rack from the cell wall and the written plan for cutting the rack apart. Specific work instructions detail the used to dismantle the rack to ensure that rigging concerns have been addressed satisfactorily. The plan also details how the tanks in the rack structure will be segmented and how heels in the tanks will be handled as mixed waste. The detailed activities and procedures for the removal of the 1 B rack is contained in Table 3a. Rack size reduction plans are detailed in Table 3b. Collect Disoersible Material from Cell Floor This part of cell cleanout is the collection of dispersible material from the cell floor. The bulk of the cesium contamination in the cell is expected to be found in the caked material on the floor under the footprints of the racks. Part of this material will be picked up after the 1 B rack size reduction, part after the size reduction of the 2A rack, and a final increment after the 1A rack size reduction is completed. The process will cleanout the drainage trench along the east wall of the cell and the sump in the northeast corner of the floor. The primary methods that will be used are scraping the

6 324 Faci 1 i ty 6-Cell Quality Process P1 an material into piles, picking up the piles with a clamshell or vacuum, then placement of the material in containers for later shipment to the PUREX tunnels as mixed waste. The detailed activities and procedures for this part of cell cleanout will be included in a table added to this document in the future. Remove and Size Reduce the 2A Rack This activity will be very similar to the 1B rack size reduction. It will cover the work required to remove the rack from the wall and a specific plan for dismantlement of this rack to account for any possible rigging concerns. The tanks in the 2A rack are expected to have minimum heals as these tanks were condensate receiver vessels. The detailed activities and procedures for this part of cell cleanout will be included in a table added to this document in the future. Size Reduce the 1A Rack This phase of the project will size reduce the 1A rack. This rack has already been disconnected and pulled from the wall in to the cell. The specific plan for the reduction of this rack will include the very specific way the tanks in the rack will be dismantled to contain the internal parts of the tanks. This rack contains the process evaporator, tank TK-113, which is expected to contain a potential holdup of 1.5M curies of heel material. The size reduction planning will also address the dismantlement sequence to ensure all rigging concerns are addressed. The detailed activities and procedures for this part of cell cleanout will be included in a table added to this document in the future. Load and ShiD Mixed Waste to PUREX Tunnels This part of the cleanout process involves the loading of the 22.5 Ton casks with the dispersible material and tank heels collected throughout the cell cleanout project. The casks will be loaded in the REC airlock and shipped to the PUREX plant by truck. The casks will be moved on to flatcars and the fully loaded railcars will be pushed into Tunnel #2. The detailed activities and procedures for this part of cell cleanout will be included in a table added to this document in the future. Move SDent Fuel to A-Cell Part of the cell inventory of equipment are seven commercial fuel bundles stored along the west wall of the cell. When the remaining FRG equipment has been removed from A-Cell the bundles will be moved through the REC airlock to A-Cell. The process will place the bundles into new thimbles supported by a new storage rack. The old thimbles 2

7 and storage racks in B-Cell will be size reduced and disposed of as LLW. The detailed activities and procedures for this part of cell cleanout will be included in a table added to this document in the future. 3
