Title: Fuels and materials development program quarterly progress report for period ending June 30, 1964

The following are reported: fuel element development (deposition of UO$sub 2$ and W--Re, fabrication of Al-base fuel plates, H$sub 2$ sorption by Al, UC fabrication with fugitive sintering aids); nondestructive test development (electromagnetic, ultrasonic, penetrating-radiation); solid reaction studies (diffusion of $sup 95$Nb into Ta monocrystals); and Zr metallurgy (Ti--Zr alloys, hydride precipitation in stressed Zircaloy-2, optical properties of Zr, preparation of monocrystals of Zr, zone refining of Zr, refractive indices of anodized oxide films stripped from Zr). (6 tables, 10 fig) (DLC)

Activities in research programs are reported on fuel element development, mechanical properties of heat resisting alloys, nondestructive testing, zirconium metallurgy, nuclear ceramics, and radiation effects on fuel materials. (JRD)
