Abstract

EN UN REACTOR DE AGUA HIRVIENDO HACES DISUELTOS DE VARILLAS DE COMBUSTIBLE (65) CONFINADAS EN MONTAJES DE COMBUSTIBLE CERCADOS EN CANALES, UN DISEÑO DE MEJORADO DE COMBUSTIBLE DE HACES DE VARILLAS DE COMBUSTIBLE INTERIOR A LOS CANALES ES REVELADO. ESPECIFICAMENTE, LAS VARILLAS DE LONGITUD PARCIAL (60) SON UTILIZADAS LAS CUALES SE EXTIENDEN DESDE LA PARTE TRASERA DEL CAMINO PARCIAL DE UN UNICO CANAL A LA PARTE SUPERIOR DEL CANAL. ESTAS VARILLAS DE LONGITUD PARCIAL (65) SON DISMINUIDAS CON RESPECTO A LAS VARILLAS SOBRANTES (65) Y ESTAN SIMETRICAMENTE DISTRIBUIDAS DURANTE TODO EL HAZ DE COMBUSTIBLE CON LA DISPOSICION PREFERIDA ESTANDO EN LA SEGUNDA FILA DEL HAZ DE LAS VARILLAS DE COMBUSTIBLE DESDE LA PARED DEL CANAL. LA DISTRIBUCION SIMETRICA DE LAS VARILLAS DE LONGITUD PARCIAL ESTA EN LA LOCALIZACION SEPARADAS UNA DE OTRA. LAS VARILLAS DE LONGITUD PARCIAL SE EXTIENDEN DESDE LA PARTE TRASERA DEL HAZ DE COMBUSTIBLE Y TERMINAN DENTRO DE LA REGION DE COCCOION. DURANTE EL CIERRE DEL REACTOR, UN MARGEN MEJORADO DEL CIERRE EN FRIO ES PRODUCIDO EN LA PARTE SUPERIOR DEL MONTAJE DE COMBUSTIBLE DEBIDO A LA PROPORCION DE "MODERADOR - A - COMBUSTIBLE" MEJORADO Y LA REDUCCION EN LA FORMACION DE PLUTONIO EN LA PARTE SUPERIOR DEL HAZ. LOS ESPACIADORES DE VARILLAS (S) Y LAS PLANCHAS ENLAZADORA DE HACES (40, 42) ESTAN PREVISTAS CON ABERTURAS (67) MAS GRANDES CUBRIENDO LAS VARILLAS DE LONGITUD PARCIAL PARA EL ACANALAMIENTO POSTERIOR DEL VAPOR Y LA REDUCCION DE LA CAIDA DE PRESION EN DOS FASES.
