A system is provided for delivering tooling, suction pickup, and alignment platforms to a stay dome region of a stem generator or the tube-free lane regions adjacent to the stay dome region and includes a suction device positioned in the stay dome region of a steam generator capable of rotating 360° about a vertical axis which also acts as a platform for mounting inter-bundle tooling and alignment devices used to position the suction device radially at any given tube location around the stay dome region to align it with an annulus based spray nozzle tube cleaning system.
