Experiments were performed to estimates waste stream encompassing, effective G-value for hydrogen generation within the transuranic waste stream IDC 003 Organic Setup sludge. This waste stream is a combination of machine cutting oils and decreasing solvents with plutonium frees sorbed into an inert gypsum or calcium silicate matrix. Four 50-g sludge samples were sealed in separate canisters. Each canister was fitted with a sampling port and pressure monitor. During the experiment one of the canister seals failed and that sample was lost from the experiment. The three remaining samples were taken through four separate test periods in which duration between beginning and ending atmosphere sampling varied from a maximum of 61 days for the first experiment to a minimum of 9 days for the fourth set of experiments.
