The present invention, (a) forming a molded body in uranium oxide nuclear fuel, and (b) mixing the powder of the additive that induces the grain growth of the sintered body during sintering; During the course of raising the temperature of the molded body to the sintering temperature range of the nuclear fuel, the method comprising: maintaining an atmosphere of the oxygen partial pressure of the additive does not melt; And it provides a method for producing a nuclear fuel sintered compact, comprising the step of increasing the oxygen partial pressure in the oxidation of the additive in the solid oxide fuel but sintering the formed body at the sintering temperature, so as to suppress the volatilization of the additive during the sintering process.
