Abstract

UNA VARILLA DE CONTROL PARA UN REACTOR NUCLEAR EN EL CUAL PLACAS DE MATERIAL ABSORBENTE DE NEUTRONES (POR EJEMPLO HAFNIO) SON UTILIZADAS EN LA PORCION SUPERIOR DE AQUEL Y TUBOS QUE CONTIENEN UN DIFERENTE MATERIAL ABSORBENTE DE NEUTRONES (POR EJEMPLO, BORO) ESTAN COLOCADOS DEBAJO DE LAS PLACAS. PARA LIBRAR A LOS TUBOS DEL PESO DE LAS PLACAS ESTAS SON SUJETAS A ELEMENTOS DE SOPORTE DE LA ESTRUCTURA DE VARILLA DE CONTROL, Y PARA IMPEDIR O REDUCIR LA SUPERFICIE DE UNA SEPARACION ENTRE LAS PLACAS Y LOS TUBOS HAY PROVISTAS UNIONES ENTRE ESTOS.
