Decommissioning of a grout- and waste-filled storage tank in the 200 East Area of the Hanford Site

Description: A self-concentrating waste tank located at the Strontium Semiworks Facility in the 200 East Area of the Hanford Site will be decommissioned following waste removal. During a previous decommissioning phase, the tank, thought to be empty, was filled with grout to prevent it from collapsing over time. Several years later, an agitator rod was pulled from within the tank and found to contain significant amounts of radiation, indicating there was still radioactive waste in the tank. Several alternati… more

Structural analysis of the central Columbia Plateau utilizing radar, digital topography, and magnetic data bases

Description: Interest in the Hanford site (Washington) as a nuclear production, power, and waste disposal site has led to generation of a vast quantity of geophysical and remote sensing data sets of the central Columbia Plateau. To data, these various studies, including at least 13 independent magnetic linear and image lineament studies, have not been adequately correlated. Therefore, these studies provide a unique opportunity to compare and contrast the viability of the different geophysical and remote sen… more

Etiology of contaminated wounds

Description: The US Department of Energy reports of events that occurred in the chemical processing 200 Areas of the Hanford Site during the period from 1972 through 1986 were reviewed to identify the causes of contaminated wounds. Contaminated wounds were reported in 19 events involving 20 workers. The causal agents (high risk operations) and the root causes were characterized. Emergency actions taken and their efficacy were noted. The 19 wound events were compared with 17 events with the potential for inh… more

Soil washing results for mixed waste pond soils at Hanford

Description: Soil washing technology was assessed as a means for remediating soil contaminated with mixed wastes primarily composed of heavy metals and radionuclides. The soils at the US Department of Energy's Hanford Site are considered suitable for soil washing because of their relatively low quantities of silt and clay. However, in a limited number of soil washing experiments using soils from different locations in the north pond of the 300 Area, the degree of decontamination achieved for the coarse frac… more

Detection and differentiation of contamination through a comparison of observed levels in historical environmental sampling data

Description: In summarizing more than a decade of environmental monitoring data from the Hanford Site, we noted that grouping data by analysis, rather than by medium, enhanced visual as well as statistical interpretations. By plotting running-averages of individual radionuclides on the same graph, for different media, we evaluated environmental trends to determine whether or not a local impact had been observed. This approach may enhance ones ability to interpret environmental monitoring data collected foll… more

Effort to earn public support and confidence in Hanford Site cleanup work

Description: Public involvement is needed for Hanford Site cleanup to succeed. If people do not know about, understand, and support cleanup, it will be more difficult and expensive. The Tri-Party Agreement calls for public involvement in decisions about cleanup options and schedules. This paper defines what public involvement means and how the Washington State Department of Ecology (Ecology), US Environmental Protection Agency (EPA), and US Department of Energy (DOE) have conducted it. Experience and survey… more

An HMS/TRAC analysis of a high-level radioactive waste tank

Description: It has been observed that a high-level radioactive waste tank generates quantities of hydrogen and nitrous oxide mixtures that are potentially well within flammability limits. These gases are produced from chemical and nuclear decay reactions in a slurry of radioactive waste material. The slurry is covered by a thick crust composed of sodium nitrate and nitrite salts. Significant amounts of the combustible and reactant gases are produced over a 3- to 4-month period before the crust ruptures and… more

In situ bioremediation of Hanford groundwater

Description: Liquid wastes containing radioactive, hazardous, and regulated chemicals have been generated throughout the 40+ years of operations at the US Department of Energy's (DOE) Hanford Site. Some of these wastes were discharged to the soil column and many of the waste components, including nitrate, carbon tetrachloride (CCl{sub 4}), and several radionuclides, have been detected in the Hanford groundwater. Current DOE policy prohibits the disposal of contaminated liquids directly to the environment, a… more
