The Reactor Water Cleanup (RWCU) system in a BWR plant is used to remove contaminants from the reactor water. Powdex® precoat systems are installed in many plants and ion exchange deep beds are used in others. The reactor water is cooled, treated by the RWCU system, and returned to the recirculation system. High quality Ecodex® or Powdex products are precoated and provide simultaneous filtration and deionization. Gravex® Nuclear Grade resins may be used in the deep beds. Graver Technologies products offer excellent RWCU performance.
