When engineers at the Kori nuclear power plant in South Korea found that dissolved nitrogen in reactor feed water led to an increased production of carbon 14, a long-term environmental contaminant, they sought a way to minimize its production. Membrane contactors were installed to simultaneously remove both dissolved nitrogen and oxygen from the water. This case study shares the details behind how the technology allowed the plant to reduce the formation of C14 and successfully meet the rigorous environmental and safety demands of the nuclear power industry.
