pelletペレットの焼結特性に与えるO/M比の影響Uchida, Teppei; Sunaoshi, Takeo*; Kato, Masato
MOX fuel pellets are produced from UO and PuO powders by mechanical blending method. It is important to control pellet density in the pellet production. To investigate the change of the sintering rate depending on O/M ratio is important for MOX pellet production. The purpose of this work is to investigate the densification behavior of PuO which is one of the starting materials as a function of O/M ratio. Thermal dilatometer was employed to measure pellet densification. The measurements were carried out in atmosphere of air and Ar/H gas mixture added moisture. Powder of PuO was pressed and measured at 1923 K in various conditions. The changes of grain size and densification rate were observed with O/M ratio. The PuO pellet sintered in air was very low density of 84%TD. The highest density pellet of 96%TD was obtained by sintering at O/M ratio of about 1.99.
