OSTI ID:4156891

Pu-U alloys suitable for use as fuel in fast breeder reactors and having good fabrication characteristics can be prepared by mixing an alloy comprising Pu and U in the ratios 1:9 to 1:1 and 7 to 40 at.% Fe, Ni, Co, and/or Mn. The latter group of metals does not moderate or capture fast neutrons and improves the working properties of the alloy by keeping the amount of the (ZETA) phase small. From 7 to 40 at.% of these metals will keep the (ZETA) phase small, although 14.3 at.% is the amount that will form the preferred tetragonal crystal structure of the U/sub 6/Mn type. Six examples of the preparation of such alloys are given. (D.L.C.)
