Abstract

VARILLA DE CONTROL DESTINADA A SER UTILIZADA EN UN REACTOR NUCLEAR. DICHA VARILLA (22) INCLUYE UN DISPOSITIVO DE SOPORTE (14) QUE PERMITE A AQUELLA REALIZAR UN MOVIMIENTO AXIAL DENTRO DE UN MANGUITO (18) DE GUIA POR CUYO INTERIOR FLUYE EL REFRIGERANTE DEL REACTOR. LA VARILLA (22) DE CONTROL TIENE, EN EL EXTREMO QUE SE SITUA EN EL INTERIOR DEL MANGUITO (18), UN OBTURADOR DE CONFIGURACION CONICA ASIMETRICA QUE ES MANTENIDO EN POSICION ESTABLE CONTRA LA PARED INTERNA DEL MANGUITO (18) GUIA, AL FLUIR EL REFRIGERANTE DEL REACTOR. ESTA CONFIGURACION ASIMETRICA DEL OBTURADOR MINIMIZA LA TENDENCIA DE LA VARILLA (22) A VIBRAR COMO CONSECUENCIA DEL TORBELLINO PRODUCIDO POR EL REFRIGERANTE, Y POR TANTO SE REDUCE LA FUERZA LATERAL NECESARIA PARA MANTENERLA EN POSICION ESTABLE.
