System for cleaning, inspection and tooling delivery in the secondary side of a steam generator

A system for delivering tooling around the annulus of a steam generator comprising:

• a tooling device capable of performing a particular steam generator maintenance function;
• a locomotion system having said tooling device mounted thereto and being located in the annulus of the stem generator to be capable of moving therealong to perform said particular steam generator maintenance function;
• wherein said tooling device is a turret cleaning device having multiple high pressure water nozzles able to rotate 180 degrees about a horizontal axis enabling it to clean multiple steam generator tube lanes simultaneously;
• wherein said turret also rotates 360 degrees about a vertical axis allowing it to clean the front and back of the annulus floor and tube sheet of the steam generator;
• and
• wherein said locomotion device is an electric motor driven crawler device propelled by two bottom mounted tracks using recirculating rubber treads and having soft plastic bumpers mounted to the side thereof to prevent contact of any metal components of said crawler from contacting steam generator tubing.
