Abstract

La presente invención pertenece al campo de la tecnología de combustible nuclear, concretamente se refiere a un tipo de rejilla de componentes de combustible, componentes de combustible y núcleo de reactor de agua a presión. La rejilla de componentes de combustible de la presente invención consta de alas mezcladoras, que se forman a través de N veces de doblez cuya superficie lateral presenta la forma S, donde N ³ 2. Las alas mezcladoras de esta invención se forman utilizando múltiples dobleces y dan conducción horizontal a los fluidos por diversos pasos. La presente invención también ofrece un tipo de componente de combustible, que se utilizan varias rejillas mencionadas anteriormente colocando lo largo de la dirección axial de los componentes, las celdas de la rejilla sujetan las barras de combustible, y las alas mezcladoras de diferentes rejillas surten efecto de mezcla al agente refrigerante de manera continua. Mediante la utilización de dicho componente de combustible, igualmente, la invención proporciona un tipo de núcleo del reactor de agua a presión, en el cual mismo se reúnen los componentes de combustible de diferentes enriquecimientos, pueden descargarse unos componentes de combustible durante el periodo de cambio y cargarse unos nuevos. La invención puede mejorar el rendimiento de mezcla de la rejilla de componentes de combustible y al mismo tiempo fortalecer la capacidad de transferencia de calor del agente refrigerante, por lo tanto, se perfecciona el desempeño térmico de los componentes combustible nuclear.
