A flow-through system for determining the particle size distribution of iron oxide particulate matter in a reactor water sample. The system includes a magnetic filter having a chamber through which a stream of reactor water. The chamber is surrounded by a winding which is coupled to an electrical circuit for generating a varying magnetic field which interacts with any magnetic particulates entrained in the water sample flowing through chamber. When a strong magnetic field is established, magnetic particles are filtered out of the water stream flowing through the chamber by magnetic attraction. Therefore, only particles which are non-magnetic or slightly magnetic pass through the magnetic filter. The particles which pass through the magnetic filter then enter a conventional particle distribution analyzer which counts and sizes the particles in the water stream flowing therethrough.

Magnetic and ultrasonic discriminator for particle size distribution

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.

Colloidal resin slurry recycle concentrating system of nuclear reactor

Water testing means for monitoring circulating water coolant in service within a water cooled nuclear reactor system is disclosed. The invention is an improvement in such water testing means and comprises a preconditioning of selected sample specimens of water with a pH adjustment for inhibiting unbalancing an equilibrium in solution of water coolant with ion solutes.

Method for testing the soluble contents of nuclear reactor coolant water

Water testing apparatus for monitoring circulating water coolant in service within a water cooled nuclear reactor system is disclosed. The invention is an improvement in such water testing apparatus and comprises filtering and a preconditioning of selected sample specimens of the coolant water with a pH adjustment for inhibiting unbalancing an equilibrium in solution of water coolant with ion solutes.

Apparatus for filtering and adjusting the pH of nuclear reactor coolant

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.
