Abstract

EN UN GRUPO DE COMBUSTIBLE (40) PARA USO EN UN REACTOR NUCLEAR DE AGUA EN EBULLICION, VARILLAS DE LONGITUD PARCIALES (P) CON TENDENCIA A REDUCIR LA CAIDA DE PRESION SE UTILIZAN EN COMBINACION CON ESPACIADORES (S1-S8) Y DISPOSITIVOS FIJADOS EN ESPACIADORES PARA REPARAR LA CAIDA DE PRESION PARA LOGRAR UNA POTENCIA MEJORADA. LA ADICION DE VARILLAS DE LONGITUD PARCIALES TIENE LA VENTAJA DE REDUCIR LA CAIDA DE PRESION. ESPACIADORES ADICIONALES O DISPOSITIVOS FIJADOS A ESPACIADORES RECAPTURAN BASICAMENTE LA CAIDA DE PRESION. MECANISMOS FIJADOS A ESPACIADORES EJEMPLARES PARA LA RECAPTURA DE CAIDA DE PRESION SE FIJAN INCLUYENDO ALETAS, PREFERENTEMENTE ALETAS DE TORBELLINO EN LOS ESPACIADORES, DISMINUYENDO EL PASO DE ESPACIADOR PARA AUMENTAR EL NUMERO TOTAL DE ESPACIADORES EN LA ZONA DE DOS FASES SUPERIOR DEL GRUPO DE COMBUSTIBLE, AUMENTANDO LA ALTURA VERTICAL DE LOS ESPACIADORES, Y AUMENTANDO EL GROSOR DEL METAL CON QUE ESTAN CONSTRUIDOS LOS ESPACIADORES.
