Beschreibung
Zusammenfassung:	The invention provides electrochemical surface treatment apparatus (100) for the treatment of radioactively contaminated internal surfaces of a pipe (1). The apparatus (100) includes an electrode device (102). The device (102) includes an electrode (4), which, in use, is located in electrolyte liquid (2) within the pipe (1) adjacent a treatment surface (104) to be treated with a gap (106) defined between the electrode (4) and the treatment surface (104). The apparatus (100) includes a circulation arrangement (108). The electrode (4) defines an internal passage (110). In use, the circulation arrangement (108) causes a recirculating flow of electrolyte liquid (2) through the gap (106) in one direction and along the passage (110) in an opposite direction.
