Abstract

LA ESTRUCTURA DE CONJUNTO DE COMBUSTIBLE NUCLEAR TIENE UNA CONTERA SUPERIOR Y UNA CONTERA INFERIOR (10) CONECTADAS POR TUBOS-GUIAS (16) DESTINADOS A RECIBIR BARRAS DE HACES DE CONTROL Y QUE CONTIENEN, EN SU PARTE INFERIOR, UN CARTUCHO TUBULAR (20) Y ESTAN DOTADOS CADA UNO CON UN TAPON INFERIOR (22) APOYADO CONTRA LA CONTERA INFERIOR (10), PERFORADOS POR UN AGUJERO DE PASO DE UN TORNILLO DE FIJACION (26). EL CARTUCHO (20) COMPRENDE UN TAPON INFERIOR (28) APOYADO CONTRA EL TAPON (22) DEL TUBO-GUIA Y LAS FASES ENFRENTADAS A LOS DOS TAPONES (22, 28) PRESENTAN SALIENTES AXIALES QUE COOPERAN ENTRE SI PARA PROVOCAR EL BLOQUEO EN ROTACION UN TAPON CONTRA EL OTRO TAPON CUANDO DICHO TORNILLO (26) ESTA ROSCADO EN UN AGUJERO ROSCADO (32) DEL TAPON DE CARTUCHO (28).
