Abstract

UN MONTAJE DE COMBUSTIBLE NUCLEAR CON UN CONJUNTO DE BARRAS COMBUSTIBLES QUE SE EXTIENDEN LONGITUDINALMENTE (18) Y REJILLAS TRANSVERSALES SEPARADAS AXIALMENTE (16A) CON CELULAS (44) PARA RECIBIR LAS BARRAS COMBUSTIBLES (18) EMPLEA DISPOSITIVOS DE PROTECCION ANTI-ROZAMIENTO (40) PARA PROTEGER LAS PARTES FINALES INFERIORES (23A) DE LOS REVESTIMIENTOS METALICOS TUBULARES (23) DE LAS BARRAS COMBUSTIBLES (18) POR EL DAÑO QUE PUDIERA SUPONER EL CONTACTO CON ESCOMBROS ARRASTRADOS HACIA EL INTERIOR POR EL FLUJO DE REFRIGERANTE A TRAVES DEL MONTAJE DE COMBUSTIBLE. CADA DISPOSITIVO TIENE LA FORMA DE UN MANGUITO HUECO (40) DISPUESTO SOBRE LA PARTE FINAL INFERIOR (23A) DE UN REVESTIMIENTO METALICO DE BARRA COMBUSTIBLE (23) Y EXTENDIENDOSE COEXTENSIVO A ESTA. EL MANGUITO TIENE UNA PARTE SUPERIOR (52) QUE SE EXTIENDE A TRAVES DE UNA CALULA DE REJILLA (44) ENTRE LOS EXTREMOS SUPERIOR E INFERIOR (44A Y 44B) Y UNA PARTE INFERIOR (54) POR DEBAJO DE DICHA CELULA DE REJILLA DESDE EL EXTREMO INFERIOR (44A) HASTA EL EXTREMO DEL FONDO (23B) DEL REVESTIMIENTO METALICO DE BARRA COMBUSTIBLE SEPARADO POR DEBAJO DEL EXTREMO INFERIOR DE LA CELULA DE REJILLA (24B).
