Abstract

Perfeccionamientos en dispositivos para inactivar un reactor nuclear, caracterizados por comprender un tubo preparado para ajustar un canal vertical en el núcleo del reactor, el tubo tiene su extremo interior, no destinado a la carga, normalmente cerrado y contiene un elemento que proporciona un espacio anular limitado por la pared del tubo y el elemento citado y que puede recibir, al descargarse de un almacén situado por encima de dicho tubo un gran número de bolas de absorción de neutrones, el tubo mencionado puede separarse del núcleo y tiene su extremo inferior preparado para abrirse con objeto de recuperar las mencionadas bolas después de funcionar el dispositivo.
