ABSTRACT:
Sulphidation method for a UO2powder, in which said powder is sulfurated by bringing it into contact with a gaseous sulphidation agent.Method for manufacturing nuclear fuel pellets based on uranium oxide, or mixed oxide of uranium and plutonium, from a load of totally or partially sulfurated UO2powder or UO2powder and PuO2powder, by lubrication, pelletizing and sintering, in which: the load of powder subjected to the lubrication, pelletizing and sintering is prepared by the following successive steps:sulphidation of a UO2powder by the above sulphidation method;optionally mixing, said sulfurated powder in a matrix comprising a UO2powder, or of a UO2powder and a PuO2powder;and, subjecting said load, formed from said sulfurated powder or said mixture, to lubrication, pelletizing and sintering operations.
