Early physical model studies of the diffusers at Browns Ferry Nuclear Plant qualitatively document the mixing characteristics of the thermal effluent. Based on these studies, the dilution formulation presented by E. E. Adams was selected to predict the plant-induced temperature rise in Wheeler Reservoir. Field studies during 1982-1983 compiled temperature data to evaluate the applicability of Adams' analysis to diffuser performance at Browns Ferry. A computer model for real-time monitoring of thermal compliance which incorporated this formulation was developed.
