Design and construction of model steam generators for corrosion testing of alternative materials. [PWR]
This topical report describes the design and construction of two model steam generators which were built to test the corrosion resistance of contemporary and alternative steam generator materials under secondary water conditions. The models include several new design features rendering them more representative of actual steam generators. Extensive thermal and hydraulic analyses of the models are also presented and discussed. Support designs incorporated in the model steam generators were drilled support plates and broached trefoil support plates of Type 405 stainless steel, Breda Termomeccanica lattice supports of Type 347 stainless steel, and eggcrate supports from Types 347, 409, and SCR-3 stainless steels and Alloy 600. In addition, the drilled support plates included bushing inserts of Type 347 and SCR-3 stainless steels, Alloys 600 and 690, and carbon steel. Heat transfer tubing was comprised of mill annealed, thermally treated, process stabilized, and sensitized Alloy 600, as well as mill annealed Alloy 690 and Alloy 800.
