The macroscopic fission cross sections for the PuO/sub 2/-U0/.sub 2/ mixed crystal oxide capsules were determined. The sinterability of U0/sub 2/ and U0/sub 2/-PuO/sub 2/ was compared. The extrusion of Al-U alloy billets is described. In the process of Pu recovery from irradiated Al-Pan alloys by molten bismuth and silicon addition, experiments are being made to determine whether the Pu concentration in the resulting Al-Si alloy can be made higher than the Pu concentration in the starting Al alloy. Extranded aluminum rods were successfully loaded into Zircaloy tubes. The post-irradintion of U0/sub 2/ canned in Zircaloy-3 is continuing, and additional information is reported. Corrosion tests of steel shat in inhibited, softened water were completed. An ammonium fluoride hydrogen peroxide-acetic acid solution at pH 5 is bein- g evaluated as a pretreatment ctch for Zircaloy-2. Values of k and f were calculated from the experimental PCTR data taken with 19-rod U0/sub 2/ clusters in a 9-inch D/sub 2/0 lattice. Swelling of uranium during irradiation was studied. Gas-graphite reactions were studied for the gas-cooled central station power reactor program. (For preceding period see HW-57225-A2.) (W.D.M.)
