Abstract

EL INVENTO SE REFIERE A UN DISPOSITIVO PARA IMPEDOR LA PENETRACION EN EL SUELO DEL CORIUM DE UN REACTOR NUCLEAR FUNDIDO, ESTANDO SOPORTADO ESTE REACTOR POR UNA SOLERA DE HORMIGON APOYADA EN EL SUELO. ESTE DISPOSITIVO INCLUYE, INSERTADA EN LA SOLERA (4), UNA CUBETA DE RETENCION (6) DE MATERIAL REFRACTARIO, CUYA PARTE SUPERIOR (10) EN CONTACTO CON EL CORIUM FUNDIDO ESTA CONSTITUIDA POR UN MATERIAL REFRACTARIO Y QUIMICAMENTE INERTE RESPECTO A LOS CONSTITUYENTES DE DICHO CORIUM, Y CUYA PARTE INFERIOR (8) ESTA CONSTITUIDA DE UN MATERIAL REFRACTARIO, CUYA CONDUCTIBILIDAD TERMICA ES AL MENOS IGUAL A QUINCE VECES LA DE LA PARTE SUPERIOR. DE PREFERENCIA, LA PARTE SUPERIOR (10) DE LA CUBETA DE RETENCION (6) ES DE OXIDO DE CIRCONIO, DE 2 A 10 CM DE ESPESOR, Y LA PARTE INFERIOR (8) ES DE GRAFITO. EL DISPOSITIVO PUEDE IGUALMENTE INCLUIR MEDIOS (5) DE DESVIACION DEL ATAQUE LATERAL DE LA SOLTERA.
