NUTRAN: a computer model of long-term hazards from waste repositories

Description: The NUTRAN package of computer programs calculates doses to humans from radioactivity carried out of deep geologic waste repositories by groundwater. It consists of four codes: ORIGEN (developed by Oak Ridge National Laboratory), which treats the formation and decay of radionuclides, WASTE, which computes the transport of radionuclides in ground water, BIODOSE, which calculates radionuclide transport in surface waters and ecosystems and human exposures, and WPPLOT, which combines the results of… more

Biological Processes in the Water Column of the South Atlantic Bight: Zooplankton Responses

Description: The goal of the Fall Removal Experiment 1987 was to determine the processes affecting the dependent and fate of low salinity coastal water and of biological material therein during fall when winds are mainly south-to westward. Five zooplankton taxa, Acartia tonsa, (A. tonsa) Paracalanus species (sp), Temora turbinata (T. turbinata), Oncaea sp, and Sagitta enflata were examined. Data on the distribution of all five taxa were presented, and distribution over time was also studied. The abundance o… more

Inversion approach for thermal data from a convecting hydrothermal system. Revision 1

Description: Hydrothermal systems are often studied by collecting thermal gradient data and temperature-depth curves. These data contain important information about the flow field, the evolution of the hydrothermal system, and the location and nature of the ultimate heat sources. Thermal data are conventionally interpreted by the ''forward'' method; the thermal field is calculated based on selected initial conditions and boundary conditions such as temperature and permeability distributions. If the calculat… more

OTEC platform configuration and integration. Volume II. Technical concept. Final report

Description: The configuration, integration, and evaluation studies performed in the first phase of this contract resulted in a ranking of the most feasible platform candidates for commercial OTEC applications. On the basis of the results obtained from three individual contractors performing the same study, the Department of Energy made selections of two platform hulls for each contractor for conceptual designs. For Phase-II studies, M. Rosenblatt and Son, Inc. (MR and S) project team was given the SPAR and… more

Emergency response monitoring activities and environmental impact of the K-Reactor aqueous tritium release of December 1991

Description: Approximately 150 gallons of tritiated water leaked from one of the K-Reactor heat exchangers between December 22 and December 25, 1991. Upon notification, the Environmental Technology Section (ETS) activated its emergency response team to provide predictions of river concentrations, transport times, and radiological effects to downstream water users. Additionally, within a few days of the release, ETS and the Environmental Monitoring Section (EMS) began a comprehensive program to collect and a… more

Radiochemical analysis using Empore{trademark} Rad Disks.

Description: A solid-phase extraction technique that isolates specific radionuclides (i.e., {sup 89/90}Sr, {sup 226/228}Ra, {sup 99}Tc) from surface, ground, and drinking waters is described. The analyte is isolated by pulling a sample through an appropriate Empore{trademark} Rad Disk with a vacuum, and the disk is subsequently assayed by a suitable counting technique. The method has both laboratory and field applications. Interferences are discussed.
