Title:
METHOD AND DEVICE FOR SINTERING NUCLEAR FUEL PELLET
Document Type and Number:
Japanese Patent JPS52114896
Kind Code:
A
Abstract:
Sintering nuclear fuel pellets of nuclear fuel oxides having oxygen in stoichiometric excess of the dioxides by passing the nuclear fuel pellets through a reduction furnace having a reducing atmosphere under regulated exposure time or residence time to produce reduced nuclear fuel oxides of desired oxygen content. The reduced pellets are cooled and sent to an intermediate station for checking or holding. The cooled pellets from the intermediate station are sent through a sintering furnace with means for independently regulating the exposure time or residence time in the sintering furnace. Additional features are the independent control of the atmospheres and temperature as well as the humidity concentration in each furnace. Less expensive nitrogen gas may efficiently be used in the process.
