Proposals for new power plants include sections that cover water treatment and steam-generation chemical treatments. Despite the extensive research and reporting that have been conducted by such organizations as the Electric Power Research Institute (EPRI), the International Association of the Properties of Water and Steam (IAPWS), and others over the last several decades, many outdated and incorrect chemistry concepts continue to appear in project specifications. In some cases, the ideas can lead to situations that are downright dangerous for plant personnel. Most notable is the continued call for the use of a reducing agent (oxygen scavenger) in steam generators that contain no copper alloys, but others abound as well. At the least, outdated chemistry can establish conditions that lead to steam generator damage and forced outages.
