Abstract

SE SUMINISTRA UNA PLANCHA DE SUJECION INFERIOR (30) PARA UNA ESTRUCTURA DE COMBUSTIBLE NUCLEAR POR MEDIO DE UNA PIEZA DE FUNDICION INTEGRAL QUE INCLUYE UNA ARMADURA (32) QUE CONTIENE UNA PRIMERA PLURALIDAD DE PROTUBERANCIAS PARA TUBOS DE GUIA (36) EN UNA PARTE CENTRAL DE LA MISMA, UNA SEGUNDA PLURALIDAD DE PROTUBERANCIAS PARA TUBOS DE GUIA (36) CONCENTRICA CON LA PRIMERA PLURALIDAD DE PROTUBERANCIAS PARA TUBOS DE GUIA, Y UNA PLURALIDAD DE TIRANTES (34) QUE CONECTAN EL PRIMER Y EL SEGUNDO GRUPO DE PROTUBERANCIAS PARA TUBOS DE GUIA UNO CON EL OTRO Y CON LA ARMADURA. LAS PROTUBERANCIAS PARA LOS TUBOS DE GUIA SIRVEN RESPECTIVAMENTE PARA RECIBIR LAS ROSCAS DE LOS CASQUETES DE LOS TUBOS DE GUIA INDIVIDUALES DE LA ESTRUCTURA PARA COMBUSTIBLE NUCLEAR. LA PARTE SUPERIOR INTERIOR DE LA PLANCHA DE SUJECION INFERIOR ESTA CONFIGURADA PARA RECIBIR Y SOPORTAR UN TAMIZ PARA LOS DESECHOS.
