Abstract

CONJUNTO DE MUELLE Y DE GETTER DE CAMARA DE PLENO. LA INVENCION SE REFIERE A UN CONJUNTO DE MUELLE DE CAMARA DE PLENO Y GETTER PARA SU USO EN UNA BARRA DE COMBUSTIBLE NUCLEAR. EL CONJUNTO DE MUELLE (27) DE CAMARA DE PLENO Y GETTER (23) ESTAN DESTINADOS PARA MANTENER EL GETTER A UNA DISTANCIA DESEADA DE LA COLUMNA DE COMBUSTIBLE. EL MUELLE DE CAMARA DE PLENO (27) ES UNA ALAMBRE QUE COMPRENDE UNA PRIMERA SECCION ENROLLADA (27B) QUE TIENE UN DIAMETRO SUPERIOR AL DIAMETRO DEL GETTER (23) INSTALADO EN ELLA, UNA SEGUNDA SECCION ENROLLADA (27C) DE DIAMETRO INFERIOR AL DIAMETRO DEL GETTER Y QUE SOPORTA EL GETTER SOBRE ELLA, Y UNA TERCERA SECCION ENROLLADA (27D) QUE TIENE UN DIAMETRO IGUAL AL DIAMETRO SUPERIOR AL DIAMETRO DEL GETTER, ESTANDO ESTAS TRES SECCIONES CONECTADAS EN SERIE A LO LARGO DE UN EJE. CON ESTA REALIZACION DEL MUELLE (27) SE VIENE A ELIMINAR EL ALAMBRE DE CONTENCION (25A) DEL GETTER EN FORMA DE U QUE SE SUELDA AL DISCO QUE ESTA EN CONTACTO CON LA COLUMNA DE COMBUSTIBLE.
