Abstract

Perfeccionamientos introducidos en el núcleo reactor atómico para la generación de fuerza; constituídos por conjuntos de combustible, de los que por lo menos algunos acusan un gradiente de flujo de neutrones durante por lo menos un ciclo de operación, siendo los mismos desplazados a otra posición del referido núcleo reactor durante un subsiguiente de operación; caracterizados porque los mencionados conjuntos de combustible tienen una reducida reactividad en los lugares opuestos al referido gradiente del flujo de neutrones, reactividad ésta que está reducida con respecto a la reactividad del resto de los mencionados conjuntos de combustible.
