COATING FOR URANIUM FUEL ELEMENTS
Zirconium-tin alloys in the range 1 to 15% tin have advantages for use as coatings or casings for uraninm fuel elements, viz., low neutron capture cross section and high corrosion resistance. Several ways of preparing such alloys are given. Corrosion rate data are given for a large number of Zr-Sn alloys, using 315 deg C water and 400 deg C steam at 1500 psi, which demonstrate their increased corrosion resistance over that of pure zirconium, except for alloys with high tin contents on the order of 25%. As an example of coating fuel elements with Zr-- Sn alloys, a Zr--U/sup 235/ fuel block can be encased in a Zr-- Sn block and covered with two Zr-- Sn plates, bending being effected by rolling.
