Abstract

Un mecanismo para accionar las barras de control, (CRDM), comprende un tornillo de guía, a motor acoplado mediante rosca al tornillo de guía para accionar linealmente el tornillo de guía en una direccion de insercion o en una direccion opuesta, de retraccion, un conjunto de cerrojos asegurado al tornillo de guía y configurado para: (i) acerrojarse a una barra de conexion, y para: ii) desacerrojarse con respecto a la barra de conexion, teniendo la barra de conexion libertad para moverse en la direccion de insercion cuando está no acerrojada, y un mecanismo de liberacion configurado para desacerrojar selectivamente el conjunto de cerrojos con respecto a la barra de conexion.
