Aeromonas distribution and survival in a thermally altered lake

Description: Par Pond is a thermally enriched monomictic southeastern lake which receives heated effluent from a production nuclear reactor. Fish populations in the lake have lesions of epizooty from which Aeromonas spp. are readily isolated. Distribution and population densities of Aeromonas in the water column were measured along an oxygen and temperature gradient. Greater population densities of Aeromonas occurred below the oxygen chemocline when the lake was stratified. Survival of A. hydrophila under i… more

Field studies of submerged-diffuser thermal plumes with comparisons to predictive model results

Description: Thermal plumes from submerged discharges of cooling water from two power plants on Lake Michigan were studied. The system for the acquisition of water temperatures and ambient conditions permitted the three-dimensional structure of the plumes to be determined. The Zion Nuclear Power Station has two submerged discharge structures separated by only 94 m. Under conditions of flow from both structures, interaction between the two plumes resulted in larger thermal fields than would be predicted by t… more

Response of estuarine fish embryos to environmental temperature shock. Annual progress report, January 14, 1975--January 13, 1976

Description: The results have demonstrated that the most sensitive stages to acute thermal shock were the 1-2 and 2-4 cell stages of periods of cell division. Late embryos and larvae were more tolerant of temperature and chemical stress than were juveniles or adults. The level and duration of exposure was not critical at less than 40/sup 0/C for 24/sup 0/C acclimated fish. Increased incubation temperatures shortened the time to hatching and fish reared at high but non-lethal temperatures had higher feeding … more

Transport modeling in the environment using the discrete-parcel-random-walk approach

Description: When formulating a mathematical model for simulating transport processes in the environment, the system of interest can be viewed as a continuum of matter and energy or as a large set of small discrete parcels of mass and energy. The latter approach is used in the formulation of the Discrete-Parcel-Random-Walk (DPRW) Transport Model. Each parcel has associated with it a set of spatial coordinates as well as a set of discrete quantities of mass and energy. A parcel's movement is assumed to be in… more

Plankton community structure: evaluation of analytical methods using model communities. Final report. [Effects of effluents on plankton]

Description: The general purpose of this project was to provide information that might be of use to biologists who are investigating the effects of effluents on plankton. Although most applicable to non-persistent pollutants, such as thermal effluents, the methodology may be applied in some degree to nondegradable pollutants as well. The purpose of the present study was, therefore, to provide some information about the relative effectiveness of certain representative affinity tests, in circumstances that wo… more

Evaluation of environmental data relating to selected nuclear power plant sites. Kewaunee Nuclear Power Plant site

Description: Environmental monitoring data for the years 1973, 1974 and 1975 pertaining to the Kewaunee Plant, which began operation in mid-1974, were analyzed by qualitative and quantitative methods. The results showed no significant immediate deleterious effects, thus confirming preoperational predictions. Although the plant has not operated long enough to reveal long-term deleterious effects, the present indications do not lead to a prediction that any are developing. The data acquired, method of analysi… more

Interactions of Corbicula sp. with power plants. [Power plant condenser fouling by clams, use of waste heat for control of fouling by clams, and use of thermal effluents in clam aquaculture]

Description: There are three perspectives with which to view the interaction of Corbicula and power plants: as a fouling agent; as an important part of the natural ecosystem; and as a potential species for use in waste heat aquaculture. The first two of these interactions are essentially negative in character, since they involve avoidance of impacts either of Corbicula on power plant operation or of power plant operation on Corbicula. Condenser fouling by these claims has been controlled by mechanical means… more
