metallurgists, and designers. </div> <div> <B>Background </B></div> <div> With the increase of unit sizes, stresses and heat fluxes, equipment aging, unit cycling, and the high cost of replacement power and steam, corrosion protection of the steam cycle components during operation and layup, and the control of chemistry are of critical importance. </div> <div> The cost of corrosion, and scale and deposit buildup in U.S. utility systems is over $3 billion/year.  It is even higher for industrial systems.  As much as 50% of the outage time has been attributed to problems with the boiler tubes, condensers, turbines, feedwater heaters, carbon steel piping, PWR steam generators, and BWR pipe welds.  Similar trends are found in industrial applications as well.  The cost of replacement power can be as high as $100/MWh or over one million dollars a day for a large utility unit ($7,000/MWh during the summer of 1998).  The cost of reduced or lost production in an industrial plant can be equally high. </div> <div> Significant improvements can be achieved at all levels by a better understanding of the steam cycle chemical transport, local concentration of corrosive impurities on component surfaces, and by knowledge of relevant corrosion properties of the materials used.  Cooperation of operators, chemists, the mechanical and thermodynamic designers, engineers, and management is needed to achieve these improvements. </div> <div> <B>Objectives of the Workshop </B></div> <div> <IMG BORDER="0" SRC="Symb075c00b700c800000000.gif" HEIGHT="13" WIDTH="24" ALIGN="bottom" HSPACE="0"
