The SDI Industry add-on database interface was used to input key scenario parameters. The database information can then be accessed within the model through database lookup blocks. Most non-pit plutonium from Nuclear Weapons Complex sites including SRS will be treated as necessary to create acceptable immobilization feed. The feed will be combined with ceramic formers to make an immobilized plutonium waste form, loaded into canisters, the canisters loaded into a DWPF canister, and the DWPF canister filled with HLW glass containing Cs-137. In the model, thick lines show material flow.
Thin lines show information flow, for the most part input to plotters.
The simulation model gave comparable results to those provided by spreadsheet analysis. It had significant advantages in that it allowed for rapid assessment of additional cases without reformulating the model. Additionally, the model itself documented the logic used in the analysis. Although the detail in the model was modest, it was developed rapidly, and with little modification could be used to analyze resource requirements, operating costs and shipping availability.
