Abstract
EL DISPOSITIVO (RV2) DE RETENCION DISPONE DE UN REVESTIMIENTO (B,C) PROTECTOR DE MULTICAPAS, PARA PROTEGER EL APOYO Y LA ESTRUCTURA (A) DE CONTENCION DE UNA CAMARA (5) DE DISPERSION PARA LA APLICACION DE DISPERSION Y REFRIGERACION CONTROLADA DE UNA COLADA (6) CALIENTE, EN PARTICULAR DE UNA COLADA DE NUCLEO, QUE DESPUES DE DEJAR EL RECIPIENTE A PRESION DEL REACTOR NUCLEAR EN UNA INSTALACION NUCLEAR ESTA DISEÑADA CON EL CONCEPTO DE DISPERSION, TENIENDO EN CUENTA LA CAMARA DE DISPERSION Y LA DISPOSICION DE REFRIGERACION. EL REVESTIMIENTO (B,C) TIENE AL MENOS DOS CAPAS Y CONSISTE EN: A) UNA CAPA (C) EXTERIOR DE SACRIFICIO COMO BARRERA DE CHOQUE TERMICO Y UNA SUSTANCIA DE FUSION, ASI COMO B) UNA CAPA (B) DE AISLAMIENTO Y DE PROTECCION SOBRE EL INTERIOR DE LA CAPA DE SACRIFICIO PARA EL APOYO QUE SE ENCUENTRA DEBAJO Y LA ESTRUCTURA (A) DE CONTENCION COMO PROTECCION TERMICA Y COMO CAPA DE RETENCION PARA LA COLADA CALIENTE. LA CAPA (B) PROTECTORA Y DE AISLAMIENTO CONSISTE EN UNA PRIMERA CAPA (B1) PARCIAL ADYACENTE A LA ESTRUCTURA (A) DE APOYO Y CONTENCION ELABORADA A BASE DE HORMIGON A PRUEBA DE FUEGO Y UNA SEGUNDA CAPA (B2) PARCIAL ADYACENTE A LA CAPA DE SACRIFICIO ELABORADA POR MEDIO DE BLOQUES (1) CERAMICOS RESISTENTES A LA TEMPERATURA, ESPECIALMENTE BLOQUES DE ZRO2.
