Gaussian dispersion and dosimetric modeling sensitivity to area-specific 1982--86 meteorological data collected at the Savannah River Site

Description: Radiological dose to the offsite maximum individual or the 50-mile population is often estimated assuming that operational atmospheric releases originate from the geographical center of the Savannah River Site. Historically, meteorological data collected from instrumentation on the H-Area tower have been utilized to estimate atmospheric dispersion from centrally located releases.'' This paper examines the effect on dose predictions using meteorological data from seven onsite towers located at A… more

The production of sulfate particles through the radiolytic oxidation of sulfur dioxide

Description: The production of hydroxyl radicals by the radiolytic decomposition of water vapor following alpha decay of {sup 222}Rn can be used to produce an ultrafine sulfuric acid aerosol in the presence of SO{sub 2}. In the past, the production of this aerosol appeared to have a limiting threshold in as much as sufficient conversion of SO{sub 2} to SO{sub 4} must be attained to achieve the concentration required for nucleation. This appeared to occur when the bulk average acidity reached an adequately h… more

Steam gasification of carbon: Catalyst properties

Description: This research uses several techniques to measure the concentration of catalyst sites and determine their stoichiometry for the catalyzed gasification of carbon. Both alkali and alkaline earth oxides are effective catalysts for accelerating the gasification rate of coal chars, but only a fraction of the catalyst appears to be in a form that is effective for gasification, and the composition of that catalyst is not established. Transient techniques with {sup 13}C labeling, are being used to study… more

Modeling node bandwidth limits and their effects on vector combining algorithms

Description: Each node in a message-passing multicomputer typically has several communication links. However, the maximum aggregate communication speed of a node is often less than the sum of its individual link speeds. Such computers are called node bandwidth limited (NBL). The NBL constraint is important when choosing algorithms because it can change the relative performance of different algorithms that accomplish the same task. This paper introduces a model of communication performance for NBL computers … more

Estimating the dose from atmospheric releases of HT

Description: Measurements of uptake of tritium by humans and laboratory animals following exposure to tritiated hydrogen gas, HT, suggest that the radiotoxicity of HT is four orders of magnitude less than that of tritiated water, HTO. However, this analysis does not take into account the conversion of HT into HTO following release into the environment. Experimental releases of HT have demonstrated that HT release to the environment is converted to HTO by soil microorganisms. In this report two methods are u… more

Analysis of stream bed sediments of Four Mile Creek

Description: Until 1988, solutions containing nitric acid, odium hydroxide, low levels of radionuclides (mostly tritiated water) and some metals were discharged to unlined seepage basins at the F and H Areas of the Savannah River Site (SRS) as part of normal operations. The basins are now being closed according to the Resource Conservation and Recovery Act (RCA). As part of the closure, a Part B Post-Closure Care Permit is being prepared.
