Examination of flat, natural uranium plates mechnnically clad with aluminum sheaths revealed a tendency for thermal contact between clad and core to diminish as a result of elongation and roughening of the uranium. The assemblies containing beta-quenched uranium showed less damage than those in which material rolled in the high alpha range was used. A clad rod having square cross section was found to have failed by typical internal aqueous attack of the core material. Cause of initial perforation cannot be assigned with certainty. (auth
