Abstract

An upper bundle steam generator (10) cleaning system including a cleaning head deployment and support device (50) receivable through a hand hole of the steam generator (10) and including retractable cylinders which raise the cleaning head up through the flow slots (71) to position a cleaning head about a flow slot (71) of the upper tube bundles; and a cleaning head mounted with the support device (50) for directing fluid about the tubes of the upper bundles of the steam generator (10) thereby cleaning the generator (10) from the top down flushing deposits downward during the cleaning process.
