Abstract

EL INVENTO SE REFIERE A UNA PIEZA DE SUJECION DE LAS BARRAS EN EL NUCLEO DE UN REACTOR NUCLEAR DE AGUA A PRESION. EL SISTEMA (100) CONSTA DE UNA PARTE CENTRAL (102) Y, SALIENDO RADIALMENTE DE LA MISMA, DE ALETAS (106) CON MONTANTES PARA LAS BARRAS (108). CADA ALETA (106) DEFINE UN PLANO DE SIMETRIA (136) INTERMEDIO ENTRE LAS SUPERFICIES PLANARES PRINCIPALES Y UNA CONFIGURACION DE SECCION TRANSVERSAL DEL BORDE ANTERIOR RELATIVA NO SIMETRICAMENTE AL PLANO ASOCIADO DE SIMETRIA (136), SIENDO UNIFORME Y DEFINIENDO UNA LINEA DE ESTANCAMIENTO DEL FLUJO (138) DESCENTRADA RESPECTO AL PLANO DE SIMETRIA (136). LAS ALETAS CORRESPONDIENTES (106), QUE SE EXTIENDEN EN SENTIDOS DIAMETRALMENTE OPUESTOS RESPECTO A LA PARTE CENTRAL Y QUE TIENEN PLANOS ALINEADOS DE SIMETRIA (136), CONSTAN DE LINEAS DE ESTANCAMIENTO DEL FLUJO (138) DESCENTRADAS EN UNA DIRECCION COMUN DE LOS PLANOS DE SIMETRIA RESPECTIVOS ALINEADOS (136). DE FORMA ALTERNATIVA, LOS PARES ADYACENTES DE ALETAS DESPLAZADAS EQUIANGULARMENTE PUEDEN TENER DICHOS DESCENTRAMIENTOS DIRIGIDOS EN SENTIDO OPUESTO, DE FORMA COMUN PARA TODOS LOS PARES.
