Abstract

DISPOSITIVO PARA ASEGURAR LOS ENSAMBLAJES QUE FORMAN EL NUCLEO DE UN REACTOR NUCLEAR Y PERMITE ADOPTAR EL CAUDAL DE LIQUIDO DE ENFRIAMIENTO A LAS NECESIDADES. CONSTA DE UN PIE DE POSICIONAMIENTO, FORMADO POR UN CUERPO CILINDRICO HUECO (2), REUNIENDOSE ESTE POR UNA PIEZA DE ASIENTO ESFERICA (3) A UNA CARCASA ABIERTA (4) DISPUESTA EN LA PROLONGACION DEL PIE, Y FINALIZA EN SU EXTREMIDAD SUPERIOR EN UNA CABEZA (5). EN LA PARTE MEDIA EL CUERPO (2) COMPRENDE UNA ZONA (6) EN LA QUE ESTAN PREVISTAS UNAS ABERTURAS OBLONGAS (7), REGULARMENTE REPARTIDA ALREDEDOR DEL EJE, PERMITIENDO AL ACTUAL LIQUIDO DE ENFRIAMIENTO CIRCULAR POR EL PIE PENETRANDO EN ESTE POR LAS ABERTURAS.
