Abstract (en)
[origin: EP0027388A1] A method and apparatus for decontaminating tubes in a nuclear stream generator wherein a hone (52) mounted on a flexible tubular drive shaft is inserted into a tube and rotated while wash water is sprayed from the tubular shaft to wash away contaminants removed by the hone (52). The shaft extends through conduit (58) engaging the open end of the tube being cleaned to receive the wash water and contaminants therefrom. A cleaning mechanism (60) is disposed at the other end of the conduit (58) to discharge the wash water and contaminants and to wash and wipe the shaft while it is moved axially. With this method and arrangement the contaminants removed from the tubes are removed without contacting and contaminating any other part of the steam generator.
