The present invention is concerned with the fabrication process of low or high enrichment uranium and uranium alloy foil, and the fabrication apparatus therefor. Uranium (U) and uranium alloy [U-(A)Q-(B)X-(C)Y (Q: Al, Fe, Ni, Si, Cr, Zr element, X: Al, Fe, Ni, Si, Cr, Zr element, Y: Al, Fe, Ni, Si, Cr, Zr element, Q<> X<> Y, (A)<=1 wt %, (B)<=1 wt %, (C)<=1 wt %)] foil are directly obtained from a melt, not through a vacuum induction melting & casting, ingot cutting, hot-rolling and heat-treatment process, but through melt spinning or a twin-roll casting process. Major advantages have been obtained as follows: 1) a simplified process without the hot-rolling process and heat-treatment process, 2) an improvement in productivity and process economics in foil fabrication, and 3) a high purity and a high quality of the foil.
