Abstract
LA INVENCION SE REFIERE A UN PROCEDIMIENTO DE FABRICACION DE COMPUESTOS TIPO MONAZITA DOPADOS O NO CON ACTINIDOS, A UN PROCEDIMIENTO DE ACONDICIONAMIENTO DE RESIDUOS RADIACTIVOS RICOS EN ACTINIDOS Y EN LANTANIDOS POR INCORPORACION DE ESTOS RESIDUOS A UNA MATRIZ DE CONFINAMIENTO A BASE DE MONAZITA, Y A UN BLOQUE DE ACONDICIONAMIENTO DE RESIDUOS RADIACTIVOS QUE COMPRENDE UNA MATRIZ DE MONAZITA QUE CONTIENE ELEMENTOS RADIACTIVOS. DICHO PROCEDIMIENTO COMPRENDE LA MEZCLA EN FASE SOLIDA DE REACTIVOS QUE INCLUYEN UN COMPUESTO DEL TIPO METAFOSFATO DE LANTANIDO INACTIVO DE FORMULA LN(PO 3 ) 3 Y UNO O VARIOS OX IDOS DE LANTANIDO Y/O UNO O VARIOS OXIDOS DE ACTINIDO, O UNO O VARIOS COMPUESTOS SUSCEPTIBLES DE PRODUCIR ESTE O ESTOS OXIDOS EN EL TRATAMIENTO TERMICO DE SINTERIZACION - REACCION, LA CONFORMACION DE LA MEZCLA ASI OBTENIDA Y LA SINTERIZACION - REACCION DE DICHA MEZCLA CONFORMADA, CON LO QUE SE OBTIENE UNA MONAZITA O UN COMPUESTO TIPO MONAZITA.
