Abstract

MODULO DE COMBUSTIBLE NUCLEAR DE FORMA SUSTANCIALMENTE CILINDRICA. CARACTERIZADO PORQUE LAS BASES DE LA FUNDA PROPORCIONAN UN PAR DE CAVIDADES SUSTANCIALMENTE CONICAS Y AXIALES QUE TIENEN LOS VERTICES RESPECTIVOS VUELTOS HACIA EL CENTRO DEL MODULO; PORQUE EL MAYOR DIAMETRO DE DICHAS CAVIDADES SUSTANCIALMENTE CONICAS ES MENOR O IGUAL QUE LA MITAD DEL DIAMETRO DEL MODULO DE COMBUSTIBLE; PORQUE DICHAS CAVIDADES TIENEN UNA SECCION DIAMETRAL EN FORMA DE U, ESTANDO LOS BRAZOS DE DICHA U EXTENDIDOS HACIA LAS BASES DEL MODULO; Y PORQUE CADA UNA DE LAS BASES DEL MODULO, ADEMAS DE TENER LA CAVIDAD CONICA, ESTA PROVISTA DE UNA CAVIDAD ESFERICA.
