Abstract

PROCEDIMIENTO E INSTALACION PARA LA OBTENCION DE CUERPOS DE MATERIAL COMBUSTIBLE NUCLEAR OXIDADOS, DE ELEVADA DENSIDAD, A PARTIR DE UO2, CON ADITIVOS DE OXIDOS DE TIERRAS RARAS, TALES COMO, POR EJEMPLO, OXIDO DE GADOLINIO. SE MEZCLA EL POLVO DE MATERIAL COMBUSTIBLE NUCLEAR CON HASTA UN 10 POR 100 EN PESO DE OXIDO DE TIERRAS RARAS Y SE PRENSA HASTA UNA PROFORMA VERDE. A CONTINUACION SE SINTETIZA EN ATMOSFERA OXIDANTE A UNA TEMPERATURA COMPRENDIDA ENTRE 800 Y 1400 C DURANTE UN TIEMPO COMPRENDIDO ENTRE 15 MINUTOS Y DOS HORAS. FINALMENTE SE SINTERIZA EN ATMOSFERA REDUCTORA A UNA TEMPERATURA SUPERIOR A 1650 C DURANTE UN TIEMPO COMPRENDIDO ENTRE 30 MINUTOS Y CUATRO HORAS.
