== Abstract ==

A survey was conducted to determine operation and maintenance (O and M)-related materials needs in geothermal power plants and to identify future research and development to address these needs. A total of 44 questionnaires was mailed to geothermal plant operators and industry consultants. The response rate was 54%. The participants were asked to describe type and frequency of materials problems, strategies currently used to mitigate such problems, barriers to using new or alternative materials and technologies, sources of information and give their views on research and development priorities. A wide range of opinions was obtained, reflecting each individual respondent`s perspective and the site-specific nature of some problems. However, the consensus is that corrosion and scaling remain major issues and that components requiring performance improvements include pipelines, well casing, turbines, heat exchangers, condensers, valves and cooling towers. It is recommended that appropriate research and development continue to be directed at reducing O and M costs associated with materials failure or inadequate service. There should be a balance between optimizing existing materials through better design and understanding of behavior in geothermal environments and development of new materials. Life extension of existing equipment, service life prediction, education of plant personnel in materials andmoreÂ Â» methods for mitigating corrosion, and improvements in inhibitors and biocides would also be beneficial.Â«Â le
