Abstract

UNA REDUCCION MARCADA EN LA CAIDA DE PRESION DE UN LIQUIDO REFRIGERANTE A TRAVES DE UN SEPARADOR DE REJILLA DE UN MONTAJE COMBUSTIBLE NUCLEAR ESTA OBTENIDO POR UN PERFILADO CONVEXO DE LOS BORDES HACIA ARIBA (NORMALMENTE LOS INFERIORES) (32) DE LOS MIEMBROS DE REJILLA. PREFERENTEMENTE ESTAN HECHOS CILINDRICOS O FILETEADOS DE AIRE. ELLOS PUEDEN ESTAR HECHOS POR BISELAR PRIMERO Y ENTONCES, DECAPADOS PARA DIRIGIR UNA CORRIENTE DE UNA MEZCLA DE ABRASIVO Y UN POLIMERO ORGANICO CONTRA ELLOS, O POR TRANSPORTE DE UN ELECTRON O RAYO LASER A LO LARGO DE ELLOS EN UNA POTENCIA Y VELOCIDAD TAL QUE CAUSA UNA FUSION LOCAL. UN PERFECCIONAMIENTO MENOR ES ASEGURADO POR BISELADO EN TODA LA LONGITUD. UNA MEJORA ADICIONAL PUEDE SER OBTENIDA PARA TAMBIEN AFILAR LOS BORDES HACIA ABAJO (NORMALMENTE SUPERIORES) (34).
