Innerfilter för en drivanordning för styrstavar

摘要

A filter for a control rod drive of a nuclear reactor is adapted to be attached to a connector extending upwardly from a piston. The filter includes a base portion and a perforated filter portion, the base portion having a radially open recess adapted to receive the connector in a sideways movement. The recess is bordered by a pair of spring arms of substantially square cross-section which are adapted to resiliently grip the connector upon installation.
