This paper describes the development of an on-line analytical instrument to measure selected anions and cations over the sub-parts-per-billion to several partsper-million concentration range. The system has been designed and is being installed in an electrical generating power plant. Laboratory evaluations and limited in-plant experiences will be discussed regarding measurements of nonhydrolyzable anions and cations, transition metal ions, and organic acids. The system will accommodate multiple sample line inputs with computer-controlled options to provide sample averaging, automated sample point selection, and system standardization and calibration. The data acquisition capabilities, including storage and report generation, will also be addressed.

This paper describes the water ahemistry activities carried out in support of the Few Tube Test. This test was conducted to provide design aonfirmation data for the Clinch River Breeder Reactor Project (CRBRP) steam generators.
