The Kori Nuclear Power Plant In South Korea Uses Liqui-Cel® Membrane Contactors For Dissolved Oxygen Removal To Prevent Corrosion And Carbon 14 Production
January 30, 2005
Dissolved oxygen is a leading source of corrosion in water systems and it is carefully monitored and controlled in nuclear power plants. The Korean Electric Power Institute (KEPRI) has installed Liqui-Cel Membrane Contactors in the Kori nuclear power plant in South Korea. The membranes have been in operation since 2000 and have successfully met the rigorous demands of the nuclear power industry.
The Kori unit 1 plant is a Pressurized Water Reactor type reactor (PWR). The membranes are used to remove dissolved oxygen from water in the Primary Make-up Water Storage Tank. The water is continuously recirculated through the membrane contactor system in an effort to keep the dissolved oxygen level low. Dissolved oxygen is controlled to very low levels in this system in order to prevent corrosion of piping and equipment. Dissolved nitrogen is also controlled to prevent the formation of Carbon 14.
