Abstract

Dispositivo recuperador de núcleo para reactor nuclear de neutrones rápidos y de refrigeración por metal líquido, que incluye un durmiente de soporte del núcleo, sostenido por un pavimento que reposa contra el fondo de una cuba que contiene el núcleo y el metal líquido de refrigeración, caracterizado porque lleva un plato de gran superficie, dispuesto bajo el núcleo y perforado por una chimenea central, y una estructura de apoyo para dicho plato, que se extiende en forma de casco sensiblemente paralelo al fondo de la cuba, delimitando éste con el pavimento y el durmiente un espacio cerrado que contiene el plato y en el cual el metal líquido puede ser puesto en circulación natural bajo el efecto de las diferencias de temperatura debidas al combustible que se deposita sobre el plato y gracias a la existencia de la chimenea, asegurando dicha circulación natural la refrigeración suficiente de dicho combustible.
