- Twenty dimensional measurements were conducted on seven empty Defense Waste Processing Facility (DWPF) reference canisters. These measurements were repeated after the canisters were filled with simulated nuclear waste glass. An in-depth statistical analysis of the results indicated that changes do occur as a result of filling the steel canisters with glass poured at 1150[degree]C for four of the parameters. While small, these changes were statistically significant. The analysis indicates the maximum dimensional change found to occur after the filling for each variable. Statistical tests were used to determine if canister dimensions do significantly change, and corresponding variance information is presented. The results showed that the four measured parameters affected by filling are bottom diameter, bottom end diameter flange tilt, and lower head mismatch. Significant variability also existed for height, upper weld, ID label, lower head mismatch, and lower head ovality due to the measurements coming from different canisters. Finally, lower head mismatch showed variability caused by the data being taken at different locations on the canister. This location effect did not affect any of the other variables in this way.
