Abstract

Una herramienta de extracción del filtro exterior del mecanismo de accionamiento de barras de control de un reactor de agua en ebullición (86) que tiene una dimensión axial, adaptándose el filtro exterior (76) alrededor de una parte superior del tubo graduado (64) del mecanismo de accionamiento de barra de control (48), definiendo el filtro exterior (76) y el tubo graduado (64) un espacio anular entre los mismos, caracterizada porque se proporciona un miembro de manguito de alineación (92) que tiene un extremo distal para encajar en el espacio anular definido por el tubo graduado (64) y el filtro exterior (76); se proporciona una pluralidad de dedos (94) soportados pivotablemente por el manguito de alineación (92), teniendo cada dedo (94) un extremo distal accionado hacia fuera del manguito (92) por un muelle de presión (100); y se proporciona un collar (102) movible axialmente sobre al menos una parte de los dedos (94) para enfrentarse al muelle de presión y que impulsa los extremos distales de los dedos (94) hacia el manguito (92).
