Abstract
UNA ESTRUCTURA PARA COMBUSTIBLE NUCLEAR QUE CONTIENE UNA PLURALIDAD DE BARRAS (10) DE COMBUSTIBLE VERTICALES Y DE BARRAS VERTICALES LLENAS DE AGUA POSIBLEMENTE OCASIONALES, QUE ESTAN RODEADAS POR UN CANAL (1) PARA COMBUSTIBLE DE SECCION TRANSVERSAL SENSIBLEMENTE CUADRADA Y QUE SE DIVIDEN POR MEDIO DE UN CANAL VERTICAL (7, 8) PARA AGUA DE SECCION TRANSVERSAL SENSIBLEMENTE CRUCIFORME EN CUATRO GRUPOS, HACES DIVISORIOS (25). CADA BARRA DE COMBUSTIBLE CONTIENE UN APILAMIENTO DE PASTILLAS CIRCULARES Y CILINDRICAS (42) DE COMBUSTIBLE NUCLEAR DISPUESTAS DENTRO DE UN TUBO PROTECTOR (41). CADA HAZ DIVISORIO SE COMPONE EN TOTAL DE 25 BARRAS DE COMBUSTIBLE Y BARRAS LLENAS DE AGUA EVENTUALES DISPUESTAS EN UNA RED O ENREJADO QUE CONTIENE 5X5 BARRAS. EL TUBO PROTECTOR DE LAS BARRAS DE COMBUSTIBLE TIENE UN GRUESO DE PARED DE 0,50-0,70 MM Y UN DIAMETRO EXTERNO DE 8,5-10,3 MM.
