Abstract

A method of producing fuel pellets for nuclear reaction, in which an unsintered fuel pellet of a substantially cylindrical material, which is a powder essentially consisting of uranium oxide or plutonium oxide or a mixture thereof and optionally a neutron-absorbing oxide, is provided in a micro-wave field and maintained in a sintering temperature of 1400-1800 ℃ in a reducing gas for 6 hours; which is characterized in that (a) unsinterted fuel pellets having parallely arranged longitudinal axis are one-by-one fed to one end of a transmission pipe, the transmission pipe traversing an operation chamber having metallic walls, and the remaining volume of the operation chamber being substantially gas-tight; (b) a reducing gas is introduced into the transmission pipe, and a micro-wave field is introduced into the operation chamber; and (c) the sintered pellets are discharged from the other end of the transmission pipe on the other side of the operation chamber.
