OSTI ID:4297939

Four Zircaloy-clad capsules with Al-1.65 wt.% Pu and Al--12 wt.% Si-1.65 wt.% Pu alloy fuel cores were fabricated. The specimens were irradiated at the MTR and are awaiting return for examination. Analysis of data from Al--Pu alloy rod prepared for PCTR tests showed that segregation was present. X-ray diffraction measurements were made on differently prepared samples of PuC/sub 2/-- UO/sub 2/ mixed crystals to establish the number of phases present. A defected, Zircaloy-clad capsule with an Al--1.5 wt.% U-1 wt.% Ni--0.5 wt.% Fe alloy core was autoclaved in 300 C water. The cladding developed a single circumferential crack and suffered minor dimensional changes. Fabrication of pins, wafers. and discs for PCTR tests was initiated. The fluxmonitoring pins and wafers are to be Al-3.9 wt.% Pu alloys. Precision drilled discs of U--Pu alloy which simulate high exposure U are required. (for preceding period see HW- 51853.) (W.L.H.)
