Abstract
Reactor nuclear que incluye un núcleo de reactor nuclear situada en una vasija de reactor, un cuerpo cilíndrico de núcleo soportado en dicha vasija y que rodea el núcleo, consistiendo dicho núcleo en una multiplicidad de conjuntos de combustible de forma alargada que incluyen cada uno una multiplicidad de barras de combustible soportadas por unas rejas situadas en emplazamientos axiales predeterminados, una multiplicidad de placas deflectoras soportadas en una posición muy próxima al núcleo por una multiplicidad d elementos de guiado de núcleo montados en dicho cuerpo cilíndrico el núcleo, caracterizado porque dichos elementos de guiado del núcleo (59) están situados en dichos emplazamientos axiales predeterminados y dichas placas deflectores (58) tienen en ellas unos orificios (136) situadas río arriba, aunque muy cerca, de cada elemento de guiado de núcleo (59) para asegurar la comunicación entre el espacio situado entre las placas deflectoras (58) y el cuerpo cilíndrico de núcleo (56) con la zona de núcleo situada río arriba del emplazamiento de reja adyacente (40) con el objeto de crear en dicho espacio una presión de refrigerante igual a la presión de refrigerante que reina en el núcleo justo río arriba del emplazamiento de reja correspondiente (40).
