Concentration and distribution of copper in effluents from three freshwater nuclear power stations

Technical Report ·
OSTI ID:5624115
The concentrations and physicochemical forms of copper were determined in samples from the water column and bedload sediments in the intake and discharge zones of the Vermont Yankee, Kewaunee, and Fort St. Vrain Nuclear Power Stations. These stations differ in their mode of operation and in the composition of water circulated in their cooling systems. In addition, at Vermont Yankee, water samples were collected during changeover from open- to closed-cycle operation, and water and sediment samples were collected from the base of the cooling tower during closed-cycle operation. Copper concentrations were obtained for the soluble, including labile and bound, and particulate fractions of water samples and for bedload sediments collected in discharge and intake areas during the winter, spring, and summer months of 1978. The apparent copper complexing capacity (ACC), the dissolved organic carbon content (DOC), and the percentages of copper in different molecular-weight fractions were also determined for the soluble fraction of water samples. In addition, copper distribution coefficients (K/sub d/s of particles suspended in the water column and present in the bedload sediment were determined. 41 references, 10 figures, 20 tables.
