Abstract

SE EXPONE UN DISEÑO MEJORADO PARA EL COMBUSTIBLE, EN MANOJOS DE VARILLAS DE COMBUSTIBLE INTERIORES A LOS CANALES, EN UN REACTOR DE AGUA EN EBULLICION QUE TIENE CONJUNTOS DISCRETOS DE VARILLAS DE COMBUSTIBLE (60, 65) CONFINADAS DENTRO DE CONJUNTOS DE COMBUSTIBLE ENCERRADOS EN CANALES. ESPECIFICAMENTE, SE UTILIZAN VARILLAS DE LONGITUD PARCIAL (60), QUE SE EXTIENDEN DESDE LA PARTE INFERIOR DEL CANAL, SOLO EN PARTE DEL TRAYECTO HASTA LA PARTE SUPERIOR DEL CANAL. ESTAS VARILLAS DE LONGITUD PARCIAL (60) ESTAN ACORTADAS CON RESPECTO A LAS VARILLAS RESTANTES, Y ESTAN DISTRIBUIDAS SIMETRICAMENTE POR TODO EL GRUPO DE COMBUSTIBLE, SIENDO LA DISPOSICION PREFERIDA EN LA SEGUNDA FILA DEL GRUPO DE VARILLAS DE COMBUSTIBLE QUE FORMAN LA PARED DEL CANAL. LA DISTRIBUCION SIMETRICA DE LAS VARILLAS DE LONGITUD PARCIAL ES EN POSICIONES ESPACIADAS ENTRE SI. LAS VARILLAS DE LONGITUD PARCIAL SE EXTIENDEN DESDE LA PARTE INFERIOR DEL GRUPO DE COMBUSTIBLE Y TERMINAN EN LA REGION DE EBULLICION. SE REDUCE LA CAIDA TOTALDE PRESION, PERMITIENDO MAS VARILLAS DE COMBUSTIBLE EN EL DISEÑO O UN DIAMETRO MAS GRANDE DE LAS VARILLAS DE COMBUSTIBLE. LA RELACION DE LA CAIDA DE PRESION EN DOS FASES A LA CAIDA DE PRESION EN UNA FASE SE REDUCE TAMBIEN, TENDIENDO A INCREMENTAR EL UMBRAL DE INESTABILIDAD HIDRAULICA TERMICA, O LA INESTABILIDAD ACOPLADA NUCLEAR-TERMALHIDRAULICA. UNOS ESPACIADORES (S2) DE VARILLAS Y PLACAS DE UNION DE GRUPOS (40, 42) ESTAN DISPUESTAS, CON GRANDES APERTURAS, ABARCANDO LAS VARILLAS DE LONGITUD PARCIAL (60), PARA UNA CANALIZACION ADICONAL DEL VAPOR Y LA REDUCCION DE LA CAIDA DE PRESION EN DOS FASES. DE MANERA MAS IMPORTANTE, Y DURANTE LA SALIDA A PLENA POTENCIA DEL REACTOR, SE REDUCE LA CAIDA DE PRESION EN LA REGION DE DOS FASES SIN LA DEGRADACION SUSTANCIAL CORRESPONDIENTE DE LOS LIMITES TERMICOS DE LOS CONJUNTOS DE COMBUSTIBLE.
