Steam from the boiling water reactor of the Dresden Nuclear Power Station will enter the turbine at 869 psia and 525 F with ½ per cent moisture and with oxygen concentration higher than normal in power-plant practice. This paper discusses a series of preliminary laboratory tests evaluating the resistance of various materials for turbines and related components to erosion (impact, washing, wire-drawing) and corrosion (weight loss, pitting depths, crevice, and galvanic attack) in wet, oxygenated steam. Materials tested included carbon and low-alloy steels and cast iron, austenitic and ferritic stainless steels, Monel, cupronickels, leaded bronze, Stellite, and Ductile Ni-Resist No. 3. It is concluded that, with proper design, conventional materials may be used in the Dresden turbine except in a few critical areas.
