Abstract

Se proporciona una bomba de chorro en donde la vibración autoexcitada en una porción acoplada entre un tubo mezclador de entrada y un tubo difusor puede suprimirse sin bloquear una deformación estructural debido a una expansión térmica. Se describe una bomba de chorro comprendida de un tubo mezclador de entrada que se proporciona dentro de un recipiente de presión de reactor nuclear de un reactor nuclear de agua en ebullición y se conecta a un tubo ascendente; y un tubo difusor conectado al tubo mezclador de entrada, en donde un agua de refrigeración en el recipiente de presión de reactor nuclear forzosamente se hace circular. La bomba a chorro se proporciona con una estructura de juntas deslizantes en donde el tubo mezclador de entrada y el tubo difusor se conectan entre sí al insertar el tubo mezclador de entrada al tubo difusor desde la abertura superior del tubo difusor junto con un espacio libre (S); una estructura que amortigua la misma vibración, la forma de la cual se determina de manera que, cuando el espacio libre (S) definido por la pared tubular exterior del tubo mezclador de entrada y la pared tubular interior del tubo difusor se incrementa o disminuye por la vibración del tubo mezclador de entrada o el tubo difusor, la resistencia del pasaje dentro de un pasaje de espacio libre para el agua de refrigeración suministrada, la cual se define por el espacio libre (S), no es menor que la fuerza de inercia de fluido en la totalidad del pasaje de espacio libre.
