Abstract

PROCEDIMIENTO PARA LA DISOLUCION DE OXIDOS DE TORIO Y/O DE PLUTONIO DE DIFICIL SOLUBILIDAD. CONSISTE EN CALENTAR OXIDOS EN EL INTERIOR DE UN RECIPIENTE (AUTOCLAVE) CERRADO HERMETICAMENTE A LOS GASES A ACIDO NITRICO EXENTO DE FLUORUROS. DICHOS SE CALIENTAN EN ACIDO NITRICO CONCENTRADO A UNA TEMPERATURA IGUAL O SUPERIOR A LA DE EBULLICION DEL ACIDO NITRICO A PRESION ATMOSFERICA. DICHO CALENTAMIENTO TIENE LUGAR EN ATMOSFERA GASEOSA A BASE DE OXIGENO Y/O OZONO PUROS. EL RECIPIENTE EMPLEADO ESTA HECHO A BASE DE TANTALO, ORO, PLATINO O POLITETRAFLUORETILENO O RECUBIERTO DE LOS MISMOS.
