摘要
The present invention relates to a metal containing one metal selected from the group consisting of titanium (Ti), zirconium (Zr), molybdenum (Mo), nickel (Ni), cobalt (Co), tantalum (Ta) and tungsten Mixing the silicide powder with a uranium-molybdenum (U-Mo) alloy powder at a volume ratio of 2 to 6: 1 (step 1); And a step (2) of heat-treating the mixed powder to form a coating layer containing a ternary alloy on the surface of the uranium-molybdenum (U-Mo) alloy powder (step 2). Molybdenum alloy powder. The method for producing a uranium-molybdenum alloy powder in which a ternary alloy coating layer according to the present invention is formed can produce a uranium-molybdenum alloy powder in which a uniform uranium-metal-silicon ternary alloy coating layer is formed, It is possible to reduce the amount of swelling of the nuclear fuel by blocking the possibility of intrusion into the inside of the nuclear reactor, thereby improving the soundness of the nuclear fuel.
