Results are reported from research project to obtain data on the behavior of potentially toxic substances introduced into surface waters from nuclear power plants, the impact magnitude of these substances on representative and economically important aquatic species, and the development of models with which to predict the partitioning of these substances among the abiotic aquatic compartments. Data are included from an investigation of copper partitioning in freshwater and seawater, the toxicity of copper to representative marine organisms, and a mathematical model to predict copper partitioning.

Twenty-seven air tests have been completed in the /sup 1///sub 5/-scale Mark I test facility. The observed effects of vent line orifice variations on the hydrodynamic vertical load function (HVLF) are presented. The conditions for standard tests, to which the orifice variation tests are compared, are defined and discussed. These tests used the ''standard'' or 9.5 inch orifices in the 90/sup 0/ sector vent lines.
