Abstract

UNA VARILLA DE COMBUSTIBLE NUCLEAR EN LA QUE TODAS LAS PASTILLAS DE COMBUSTIBLE ESTAN COMPUESTAS DE UN MATERIAL FISIBLE QUE TIENE UN ENRIQUECIMIENTO SENCILLO, Y EN LA QUE LAS PASTILLAS ESTAN APILADAS HASTA UNA LONGITUD QUE DEJA SOLO UN PEQUEÑO HUECO ENTRE EL EXTREMO SUPERIOR DE LA PILA Y EL TAPON EXTREMO SUPERIOR DE LA VARILLA DE COMBUSTIBLE, HUECO QUE ESTA DESPROVISTO DE ESTRUCTURA ALGUNA, TENIENDO LAS PASTILLAS CONFIGURACIONES ANULARES EN LAS ZONAS EXTREMAS OPUESTAS DE LA PILA. EN UNA REALIZACION, TODAS LAS PASTILLAS DE COMBUSTIBLE DE LA ZONA DE LA PILA ENTRE DICHAS ZONAS EXTREMAS TIENEN CONFIGURACIONES MACIZAS. EN OTRA REALIZACION LA ZONA DE LA PILA ENTRE SUS ZONAS EXTREMAS ESTA DIVIDIDA EN UNA ZONA DE PASTILLAS DE COMBUSTIBLE MACIZAS Y UNA ZONA DE PASTILLAS ANULARES QUE TIENEN UN TAMAÑO DE OQUEDAD MENOR QUE LAS PASTILLAS ANULARES DE LAS ZONAS EXTREMAS.
