An upper bundle steam generator cleaning system including a cleaning head deployment and support device receivable through a hand hole of the steam generator and including retractable cylinders which raise the cleaning head up through the flow slots to position a cleaning head about a flow slot of the upper tube bundles; and a cleaning head mounted with the support device for directing fluid about the tubes of the upper bundles of the steam generator for directing fluid about the tubes of the upper bundles of the steam generator thereby cleaning the generator from the top down flushing deposits downward during the cleaning process.

Upper bundle steam generator cleaning system and method

A deployment system for an upper bundle steam generator cleaning/inspection device, the deployment system including an elongated body feedable through an access in a steam generator shell proximate the tube sheet of the steam generator, the elongated body flexible in one configuration to bend into a position for extension up through flow slots in support plates of the interior of the steam generator, and rigid in another configuration for positioning and supporting cleaning/inspection devices up through the steam generator proximate the upper tube bundles of the steam generator; and a drive device for driving the elongated body up through the support plates and for retracting the elongated body back down through the support plates.
