The fabrication work started in fall, 1975 for "FUGEN" initial core mixed-oxide fuel of hundred fuel assemblies, which amounts to 18 tons PuO-UO pellets. Sofar about 7.7 ton pellets and 1326 fuelrod of 0.8% Pu-fissile fuel have been produced with strict quality control, and the production work of 0.55% Pu-fissile fuel and fuel assembly are underway. Amount of MUF in 0.8% Pu-rissilefuel production were 0.18% Pu and 0.15%U. The various presentive measure to personal radiation resulted in the lowdose rate of 160 mrem per three monthsin maximum. The preliminary evaluation of fabrication cost showed a reasonable value in a ccmparatively small scsleproduction.

The construction of the prototype heavywater reactor "FUGEN" is currentlyprogressing on the schedule to be criticalin 1976. Prior to this reactor operation,the reactor physics examination are carringout with the Deuterium Critical Assembly "DCA" since 1973. A new facility, thePlutonium Fuel Fabrication Facility (PFFF)of PNC which is mainly devoted to mass-production, was constructed to meet theplutonium fuel fabrication requirement forPNC's FBR and ATR projects. At the "ATR line" of this PFFF, thefabrication of the plutomium fuel elementsfor DCA had been carried out since Mar. 1972, and 92 fuel assemblies with the totalmixed-oxide amounting to as much as 10tons were completed in Feb. 1973. It was the first experience in Japanthat,such a large amounts of mixed-oxidewas fabricated as the fuel assembliescomposed of three kinds of fuel rodsaccording to both the isotopic charactor and the plutonium enrichment, totaling about2600 fuel rods.
