Reactor Water Cleanup
Graver Technologies provides a range of ion exchange and septa technologies to yield an economical filtration and purification solution for reactor water cleanup.
Superior Performance Ion Exchange Resins and Septa for Reactor Water Cleanup Systems
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.
