Abstract

Los ensambles de combustible nuclear incluyen por lo menos una estructura de control de fluencia para el uso en un núcleo de reactor nuclear con otros ensambles de combustible nuclear; tales ensambles y estructuras que limitan el flujo pueden ser posicionados fuera de o alrededor de los otros ensambles de combustible nuclear en el núcleo para reducir el flujo de neutrones más allá de los ensambles de combustible nuclear de fluencia controlada, y las estructuras de control de fluencia pueden ser posicionadas en una orilla exterior del núcleo; las estructuras de control de fluencia limitan el flujo de neutrones con materiales no combustibles en estructuras como barras de combustible e insertos, canales, cortinas de protección, etc. en posiciones particulares en los ensambles de combustible; un ingeniero puede seleccionar y/o instalar los ensambles de combustible que limitan la fluencia con características que limitan el flujo en núcleos que tienen perfiles neutrónicos que se espera se beneficien de tal limitación de flujo.
