Abstract

EN UN ENSAMBLAJE DE COMBUSTIBLE (40) PARA UN REACTOR DE AGUA PRESURIZADA, VARILLAS DE COMBUSTIBLE (48) EXTENDIDAS HACIA ARRIBA DE UNA CHAPA DE REFUERZO INFERIOR (42). LAS TAPAS DE EXTREMO INFERIORES (49) DE DICHAS VARILLAS DE COMBUSTIBLE (48) ESTAN ASEGURADAS DENTRO DE APERTURAS (70) EN LA CHAPA DE REFUERZO INFERIOR (42). VENTAJOSAMENTE, UN MUELLE (74) ESTA DISPUESTO DENTRO DE CADA APERTURA (70) Y EJERCE FUERZAS LATERALES CONTRA LA CHAPA DE REFUERZO INFERIOR (49) PARA PREVENIR O REDUCIR VIBRACIONES. ASI RESULTA UNA ALTURA ACTIVA EXTENDIDA DE LAS VARILLAS DE COMBUSTIBLE SIN UN DESCENSO EN LA PRESION INCREMENTADA A LO LARGO DE TODO EL ENSAMBLAJE, Y CONSECUENTEMENTE UN POSIBLE AUMENTO DE LA ENERGIA GENERADA POR EL ENSAMBLAJE, COMPARADA CON DISEÑOS DE ENSAMBLAJE ANTERIORES.
