Abstract

Dispositivo para el control del flujo de refrigerante a y en un conjunto de combustible para un reactor nuclear del tipo BWR (reactor de agua en ebullición) o PWR (reactor de agua a presión), en el que el conjunto de combustible incluye una chapa de unión superior (1), una chapa de unión inferior (2), barras de combustible (4) y separadores (3), estando conectadas dichas dos chapas de unión (1, 2) por elementos, como un primer tipo de tubos de guía de barras de control (15) o una pared de conjunto de combustible (5), y estando provistas de una pluralidad de aberturas (7, 8) para el flujo de refrigerante, incluyendo además el conjunto de combustible elementos alargados soportados directa o indirectamente por la chapa de unión superior (1) y/o la chapa de unión inferior (2), como barras de combustible (4) y/o tubos de guía de barras de control (17) de un segundo tipo, caracterizado porque dichos elementos (4, 17) exhiben un crecimiento por irradiación en su dirección longitudinal que se desvía del de dichos miembros (5, 15) y porque dichos elementos (4, 17) están provistos de cuerpos de estrangulamiento (9, 14, 16) que cooperan con las aberturas (7, 8) en la chapa de unión superior (1) y/o la chapa de unión inferior (2) de tal forma que el cambio de la posición relativa entre dichos cuerpos de estrangulamiento (9, 14, 16) y dichas aberturas (7, 8), producido por el diferente crecimiento por irradiación de dichos elementos (4, 17) y dichos miembros (5, 15), produzca un cambio y/o una redistribución del flujo de refrigerante dentro de los conjuntos de combustible separados y/o entre los conjuntos de combustible del reactor nuclear.
