Abstract

MONTAJE DE COMBUSTIBLE LIQUIDO PARA UN REACTOR NUCLEAR HIRVIENTE. EL CANAL SE CONECTA A UN REFRIGERANTE QUE DEBE FLUIR A TRAVES DEL CANAL. SE DISPONE DENTRO DEL CANAL UN HAZ DE VARILLAS DE COMBUSTIBLE (1) DE UNA LONGITUD SIMILAR, RETENIDAS POR UNA PLURALIDAD DE ESPACIADORES (8, 9). DE ACUERDO CON ESTA INVENCION, SE DISPONE EN LA PARTE SUPERIOR DEL MONTAJE DE COMBUSTIBLE LIQUIDO, AL MENOS ENTRE UN PAR DE ESPACIADORES, UNA MANGA (10) FORMADA POR UNA CAPA ALREDEDOR DEL HAZ. LA MANGA (10) TIENE UNA FORMA EXTERNA QUE SE CONFORMA CERCA DE LAS PAREDES DEL MONTAJE DE COMBUSTIBLE LIQUIDO (7) QUE RODEA A DICHO HAZ. ESTA CAPA ESTA PERFORADA POR UN GRAN NUMERO DE ABERTURAS PARA REDUCIR LA RESISTENCIA DE FLUJO GENERADA POR LA CAPA (FIG 2).
