H-Area Seepage Basins

Description: During the third quarter of 1990 the wells which make up the H-Area Seepage Basins (H-HWMF) monitoring network were sampled. Laboratory analyses were performed to measure levels of hazardous constituents, indicator parameters, tritium, nonvolatile beta, and gross alpha. A Gas Chromatograph Mass Spectrometer (GCMS) scan was performed on all wells sampled to determine any hazardous organic constituents present in the groundwater. The primary contaminants observed at wells monitoring the H-Area Se… more

Po-210 as long-term integrating radon indicator in the indoor environment

Description: The general objective is to improve the knowledge about the transferring processes leading from airborne radon/radon daughters to embedded Po-210 in hard surfaces in the indoor environment. The specific goal of the research is to identify situations in which the surface activity of Po-210 can be used as a long-term indicator of lung cancer risk from past or future radon exposures.

Genes and gene expression: Localization, damage and control -- A multilevel and inter-disciplinary study

Description: All projects are working toward a goal for describing the three dimensional nuclear topography in terms of relative spatial relationships among genes (specific DNA sequence). Methods are now being perfected to detect these genes, quantitatively and spatially, to perturb these genes specifically, and to measure the perturbation in order to assure specificity. We are developing methods to assay, after perturbation of the target DNA within living cells, whether or not only the target sequence are … more

Thulium-170 heat source

Description: An isotopic heat source is formed using stacks of thin individual layers of a refractory isotopic fuel, preferably thulium oxide, alternating with layers of a low atomic weight diluent, preferably graphite. The graphite serves several functions: to act as a moderator during neutron irradiation, to minimize bremsstrahlung radiation, and to facilitate heat transfer. The fuel stacks are inserted into a heat block, which is encased in a sealed, insulated and shielded structural container. Heat pipe… more

Three-dimensional contaminant plume dynamics in the vadose zone: Simulation of the 241-T-106 single-shell tank leak at Hanford

Description: Approximately 2,000 m{sup 3} of liquid containing radioactive and chemical wastes leaked from the 241-T-106 single-shell tank at the Hanford Site. The leak discharged into the unsaturated, coarse-grained sediments of the Hanford formation which underlie the base of the tank. The PORFLO-3 computer code was used to study plume migration for {sup 106}Ru and {sup 137}Cs. The flow and transport properties of the soils through which the plume has migrated are critical input data for the model but are… more

A new experimental limit on the electric dipole moment of the electron

Description: We describe a search for the electric dipole moment d{sub e} of the electron, carried out with {sup 205}Tl atoms in the ground state. The experiment makes use of the separated-oscillating-field magnetic-resonance method, laser state selection, fluorescence detection, and two counter-propagating atomic beams. Very careful attention is paid to systematic effects. The result for the atomic electric dipole moment is d{sub a} = (1.6 {plus minus} 5.0) {times} 10{sup {minus}24} e cm. If we assume the … more

Tritium atmospheric transport and deposition following acute releases: Comparisons with a simple transport model

Description: During 35 years of operation of the Savannah River Site (SRS) there have been a small number of inadvertent tritium releases to the atmosphere. After detection of the releases by stack monitors, field crews were dispatched to determine the concentration of tritium in the environment. The objective of the measurement was to verify environmental concentrations calculated by dose assessment models. Air samples were used to verify the concentration levels and tritium forms during the plume passage.… more

Radiation-induced mesotheliomas in rats

Description: Mesotheliomas have been reported in rats that inhaled plutonium, but these tumors have not been extensively studied. To investigate a possible role for inhaled radionuclides in the induction of mesotheliomas, four life-span studies conducted at the Inhalation Toxicology Research Institute are reviewed. A total of 3076 F344 rats were exposed by inhalation to aerosols of {sup 239}PuO{sub 2}, mixed uranium-plutonium oxide, or {sup 144}CeO{sub 2}. Results showed that a low incidence of pleural meso… more

Tritium distribution in the environment in the vicinity of a chronic atmospheric source-assessment of the steady state hypothesis

Description: The Savannah River Site (SRS) is a major radionuclide production center. Tritium has been released to the atmosphere over the 36 year period of operation. The tritiated water concentration of the atmosphere, rain, vegetation and food have been routinely monitored during this period. Special studies have been made of tritium in soils and in the organic fractions of these same materials. The available data suggest that the average tritium concentration in the components of the terrestrial environ… more

Analysis of soil and water at the Four Mile Creek seepline near the F H Areas of SRS

Description: Until 1988, solutions containing sodium hydroxide, nitride acid, 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 (Killian et al, 1987a,b). The basins are now being closed according to the Resource Conservation and Recovery Act (RCRA). As part of the closure, a Part B Post-Closure Care Permit is being prepared. The information included in this report w… more

Field measurements and assessment of retrievable-stored TRU waste at Savannah River Site

Description: Accountability and nuclear safety concerns arising from uncertainties in Pu-239 loadings of a number of waste containers at SRS were investigated by in situ neutron and gamma-ray measurements and an assessment of risk stemming from past waste analysis and packaging practices. The neutron and gamma measurements largely confirmed the correctness of original waste analysis and accountability, while the risk assessment and measurement implications suggested no present or foreseeable nuclear safety … more

Description: Aluminum-27 Double Rotation NMR spectroscopy (DOR) has been used to investigate framework ordering in the aluminophosphate molecular sieves VPI-5, AlPO{sub 4}-5, and AlPO{sub 4}-8. Well resolved peaks in the {sup 27}Al DOR spectra of both hydrated and dehydrated VPI-5 allow isotropic shifts to be correlated with local framework structure. more distorted aluminum environments are reflected by broader lines in {sup 27}Al DOR spectra of AlPO{sub 4}-5 and AlPO{sub 4}-8.

Decomposition of sodium tetraphenylborate

Description: The chemical decomposition of aqueous alkaline solutions of sodium tetraphenylborate, NaTPB, has been investigated. The focus of the investigation is on the determination of components which influence NaTPB decomposition. Copper(II) ions, solution temperature, and solution pH (hydroxide ion concentration) have all been demonstrated to affect NaTPB stability. Their relationship with each other and the stability of NaTPB has been determined. Based upon this knowledge, a method for stabilizing NaT… more

Resistive Wall Modes in the Reversatron II RFP

Description: The Reversatron 2 RFP (R/a=50cm/8cm) has been operated with interchangeable shells to investigate resistive wall modes. Shell penetration times are 610, 100, and 4 {mu}sec (no shell). With the 610 {mu}sec shell, the plasma current is {le} 65 kA and the duration {le} 550 {mu}sec. With no shell, helium discharges are more resistive and hydrogen discharges cannot be sustained. An m=1, n=-6 mode resonant on axis grows to a relative amplitude of 20% during the setting-up phase. With the 100{mu}sec s… more
