Irradiation test of metallic fuel at fast test reactor JOYO is planned. By using techniques of casting, fabrication, analysis and inspection, metallic fuel elements were made for the first time in Japan. In this paper, results of fabrication of U-Pu-Zr alloy fuel slug by emit casting method. Using U metal, U-Pu alloy metal and Zr metal as raw materials, fuel slugs were fabricated by emit casting apparatus in argon gas atmosphere glove box. By inspection, it was confirmed that the specifications were satisfied.
