[en] The second series of scrub alloy material characterization and dissolution studies has been performed on samples collected from scrub alloy buttons now stored at the Savannah River Site. The need for the additional laboratory work became necessary after it was established that two of the original scrub alloy buttons selected for analysis were not representative of the materials present in their respective categories. One of the categories re-examined contained plutonium-aluminum alloys and the other category contained plutonium-gallium alloys
