Abstract
EL INVENTO SE REFIERE A UN PROCEDIMIENTO DE TRATAMIENTO DE APATITOS NATURALES PARA SU UTILIZACION EN EL ALMACENAMIENTO DE ELEMENTOS COMBUSTIBLES IRRADIADOS. ESTE PROCEDIMIENTO CONSISTE EN PONER EN CONTACTO UN POLO DE APATITO NATURAL CON UNA SOLUCION ACUOSA ACIDA, POR EJEMPLO HCL O HNO3, DILUIDA DURANTE VARIOS SEGUNDOS HASTA 10 MINUTOS. ASI, SE MEJORAN LAS PROPIEDADES FISICOQUIMICAS DEL APATITO NATURAL MODIFICANDO SU COMPOSICION DE SUPERFICIE PARA APROXIMARLA AL HIDROXIAPATITO. ESTE APATITO MODIFICADO PUEDE UTILIZARSE COMO MATERIAL DE LLENADO EN LOS CONTENEDORES DE ALMACENAMIENTO DE ELEMENTOS COMBUSTIBLES IRRADIADOS.
