Abstract

An automated sludge lance and method is described for cleaning sludge from tubes in a steam generator. The lance guide and waterlance are moved inside the steam generator to direct a fluid between the tubes to effectively clean sludge from the tubes. The remote control system is mounted outside the steam generator where it is readily serviceable. The automated sludge lance and method can be used in the no-tube-lane, in the annular chamber, or in combination.
