A model steam generator including a system for facilitating the inspection of the sample tubes within the boiler vessel of the model generator is disclosed herein. The system includes means for detachably connecting the tubesheet from the primary and secondary sides of the boiler vessel. In the preferred embodiment, both end of the tubesheet and the abutting ends of the primary and secondary sides of the boiler vessel are circumscribed by tapered flanges. The tubesheet is detachably connected from the primary and secondary sides of the boiler vessel by means of Grayloc.RTM.-type annular clamps which are circumscribed by grooves for receiving the abutting flanges at the tubesheet joints. Additionally, the system includes a frame for suspending the secondary side of the boiler vessel, a wheeled cart having a jack for both laterally and vertically moving the primary side of the boiler vessel and the tubesheet into a clamping position onto the secondary side of the boiler vessel. The system further includes a set of threaded guide rods and sleeves for properly aligning the primary side and tubesheet with the secondary side of the generator. The detachably connectable Grayloc.RTM.-type joints between the tubesheet and the primary and secondary sides of the boiler vessel, in combination with the cart and screw jack, afford a convenient means of disassembling the boiler vessel and inspecting the sample heat exchange tubes within the model steam generator.
