PROCEDIMIENTO PARA LA OBTENCION DE CUERPOS SINTERIZADOS DE COMBUSTIBLE NUCLEAR OXIDICO. |
摘要 |
<p>Method for the manufacture of oxidic nuclear fuel bodies by a heat treatment of blanks obtained from UO2 starting power or a mixture of UO2 and PuO2 starting powder at a treatment temperature in the range of 1000 DEG C. to 1400 DEG initially in a gas atmosphere with oxidizing action and subsequently in a gas atmosphere with reducing action. The oxygen potential of the gas atmosphere with oxidizing action is kept in a range in which a crystallographically demonstrable U4O9 or (U, Pu)4O9 crystal phase is generated in the blanks during the heating to the treatment temperature in this gas atmosphere with oxidizing action.</p> |
