Abstract

Estructura de combustible para reactor nuclear posee un conducto central vertical y que comprende un dispositivo de retículo inferior y una pluralidad de varillas de combustible (3) sustentadas por dicho dispositivo de retículo, una caja de combustible (1) que rodea todas las varillas de combustible, y una base en forma de manguito (2) con un conducto de admisión orientado hacia abajo para el fluido refrigerante del reactor, disponiendo la mencionada estructura de combustible de al menos un canal de agua vertical (4, 5) para una corriente de agua que circula a lo largo de las varillas de combustible y que se halla separado de las mismas, caracterizada por el hecho de que al menos un canal de agua vertical (4, 5) se halla hidráulicamente unido por su extremo inferior a al menos un canal que se extiende esencialmente en sentido radial (10) y que desemboca en la superficie lateral de la estructura de combustible, estando provista la pared de dicha base de al menos un orificio traspasante (12),hallándose colocado en posición dicho al menos un orificio traspasante a un nivel inferior que los orificios de salida de dichos canales esencialmente radiales (1C )y estando dispuesto en unión hidráulica con dicho conducto de admisión a través de un espacio rodeado por la referida base (2).
