  • Colloidal resin slurry recycle concentrating system of nuclear reactor coolant water
    Patent number: 5377234
    Abstract: An analytical testing means for determining the ion contents of nuclear reactor coolant water comprising ion chromatograph means and a conductivity detector. Reagent containing ion exchange resin is recycled, concentrated and the ion exchange resin regenerated to provide a more economic procedure.
    Type: Grant
    Filed: October 23, 1992
    Date of Patent: December 27, 1994
    Assignee: General Electric Company

  • System for continuously monitoring the ionic content of steam-producing water
    Patent number: 4472354
    Abstract: An on-line and continuous sampling system for monitoring the ionic content of steam-producing water in a steam-operated electrical power plant. The monitoring system comprises a plurality of sampling lines and associated apparatus for sampling the steam-producing water at a number of different points in the power plant, an ion chromatographic subsystem for analyzing the sampled water, a calibration subsystem for calibrating the ion chromatographic subsystem, and an automatic control subsystem for operating the monitoring system of the present invention.
