Estimates of DWPF canister production

Specification 1.2 of the repository program's Waste Acceptance Preliminary Specifications requires that the DWPF estimate the radionuclide inventory, and provide the error of the estimate, for each waste type (assumed to be each sludge batch). The inventory of any radionuclide is directly proportional to the number of canisters produced from that sludge batch. Thus, estimating the number of canisters to be produced from each sludge batch is an important part of complying with this specification. In this report, the number of canisters to be produced from each batch of sludge is estimated. This leads to the conclusion that approximately 5200 canisters will be produced by the DWPF through the year 2010. Thereafter, it is conservatively estimated that up to 124 canisters will be produced each year. The errors in these estimates are also discussed
