Abstract
EL ELEMENTO DE COMBUSTION (1) CONSISTE EN UN MANOJO DE BARRAS DE COMBUSTION (7, 8A, 8B, 9C, 9D, 10) ALINEADAS PARALELAMENTE Y QUE CADA UNO TIENE COMBUSTIBLE NUCLEAR EN UN TUBO DE FUNDA. EL INVENTO TIENE COMO META CREAR UNA HOMOGENEIZACION DE LA GENERACION DE POTENCIA MEDIANTE LA SECCION DEL ELEMENTO DE COMBUSTION (1) PARA MEJORAR EL APROVECHAMIENTO DEL COMBUSTIBLE. PARA ELLO SE PREVE EN UNA PRIMERA FORMA BASICA (COMPARE FIG. 3, FIG. 6), QUE POR LO MENOS ALGUNAS (8A, 9D, 10) DE LAS BARRAS DE COMBUSTION (7, 8A, 9D, 10) TENGAN UNA DIAMETRO EXTERIOR DISTINTO Y QUE LAS BARRAS DE COMBUSTION SE ENCUENTREN REPARTIDOS UNIFORMEMENTE O NO EN UNA RED BASICA PREFERENTEMENTE RECTANGULAR. SEGUN UNA SEGUNDA FORMA BASICA (COMPARE FIG. 4 Y 5) SE PREVE QUE LAS BARRAS DE COMBUSTION (7, 8B, 9C, 10) SE ENCUENTREN REPARTIDOS DE FORMA PREVIAMENTE DETERMINADA Y NO UNIFORME, PREFERENTE EN UNA RED BASICA RECTANGULAR. LA DISTANCIA (P2, P3) DE CIERTAS BARRAS DE COMBUSTION (8B, 9C, 19) SE DESVIA DE LA DISTANCIA ESTANDARD (P1). LAS DOS MEDIDAS MENCIONADAS PUEDEN TOMARSE TAMBIEN SIMULTANEAMENTE.
