Waste Isolation Safety Assessment Program: a comparison of evapotranspiration estimates using DOE Hanford climatological data

Description: Three methods of estimating monthly values of evapotranspiration on a year-round basis were compared by using the same set of long-term Hanford climatological data as input. Potential evapotranspiration calculated by all three methods yielded an annual value 5 to 9 times the mean annual precipitation. One method yields a value for actual evapotranspiration and one yields a value for areal evapotranspiration. These are compared on a monthly basis and show quite different distributions over the year. The third method examined is relatively new, was calibrated using data from arid stations, and yields results that may be more truly representative of arid areas like Hanford.

Assessment of effectiveness of geologic isolation systems. Perspectives on the geological and hydrological aspects of long-term release scenario analyses

Description: Information that may be relevant to individuals involved with analyzing long-term release scenarios of specific repositories for nuclear waste is presented. The bulk of the information is derived from recent studies in West Germany and the United States. Emphasis is on the specific geological and hydrological phenomena that, alone or in concert, could potentially perturb the area around specific repository sites. Research is continuing on most of the topics discussed within this report. Because research is ongoing, statements and conclusions described in this document are subject to change. The main topics of this report are: (1) fracturing, (2) geohydrology, (3) magmatic activity, and (4) geomorphology. Therefore, the site-specific nature of the problem cannot be overemphasized. As an example of how one might combine the many synergistic and time-dependent parameters into a concise format the reader is referred to A Conceputal Simulation Model for Release Scenario Analysis of a Hypothetical Site in Columbia Plateau Basalts, PNL-2892. For additional details on the topics in this report, the reader is referred to the Pacific Northwest Laboratory (PNL) consultant report listed in the bibliography.

Some implications of in situ uranium mining technology development

Description: The assessment indicates that there do not appear to be any significant demonstrated negative environmental impacts. Moreover, the impacts of in situ mining compare favorably with those impacts expected from conventional mining techniques. Exposure to radioactive elements is less, atmospheric emissions of radioactive and nonradioactive materials are generally less and socioeconomic impacts are decreased. In fact, because of the generally small and unskilled labor forces associated with in-situ mining, development has provided much needed economic stimulus to economically depressed areas of Texas. There are still, however, several areas of unknowns and several areas of inadequate information that will need to be addressed before a complete quantification evaluation of impacts can be made. These areas include levels of radon emissions and groundwater restoration methods and impacts. Several issues mostly relating to the interaction of industry with state and Federal regulators need to be addressed.

Some implications of in situ uranium mining technology development

Description: A technology assessment was initiated in March 1979 of the in-situ uranium mining technology. This report explores the impediments to development and deployment of this technology and evaluates the environmental impacts of a generic in-situ facility. The report is divided into the following sections: introduction, technology description, physical environment, institutional and socioeconomic environment, impact assessment, impediments, and conclusions.

Recommendations for a US geothermal research plan. Volume 1

Description: A multidisciplinary study team developed a comprehensive research program. Five- and ten-year program plans emphasize critical five-year milestones. Recommended plans are presented here under constraint of three different five-year budgets: $100, $300 and $500 million, respectively. Plans are detailed in six resource subprograms: high temperature water, moderate temperature water, hot dry rock, brine, geopressured, and dry steam. Also presented are plans for five subprograms common to all geothermal resources: exploration, assessment, drilling technology, environmental-social, and institutional. (MHR)

Review of information on hydrology and radionuclide migration at the Nevada Test Site 1976--1988, and annotated bibliography

Description: The purpose of this report is to provide information on changes in the state of knowledge on the hydrology and radionuclide migration that have occurred at the Nevada Test Site (NTS) since 1976. In the present study, a literature review was conducted to examine information published since 1976 about the various activities that have occurred at the NTS. Information was collected from the literature on the site's geological, hydrological, geochemical, and geomorphic characteristics related to the impacts on the ground water from weapons testing and the disposal of waste at the NTS. This information was used to identify the state of knowledge about the NTS and the potential impacts of NTS activities on the ground water. More than 250 reports were reviewed, of which about 200 contained information pertinent to the subject of this report. Because the reports have never been collected in a single location, only those that were supplied by the US Department of Energy and other cooperating organizations could be reviewed, and some pertinent documents may have been missed. Appendix A contains an annotated bibliography of the reports reviewed. 149 refs., 28 figs., 2 tabs.

Interim characterization report for the 300 Area process trenches

Description: This document contains information on the results of the Hazardous Waste Ground-Water Monitoring Compliance Program characterization studies of wastes disposed of in the 300 Area process trenches. The characterization of the 300 Area process trenches has been conducted as part of an effort initiated in June 1985, when a facility-specific monitoring program was implemented. The characterization effort is part of a regulatory ground-water monitoring compliance program for hazardous chemicals on the Hanford Site. The characterization work described in this document represents an expanded ground-water monitoring compliance effort, and incorporates or refers to previous studies useful in characterizing the 300 Area. This document is primarily a compendium of technical information on the 300 Area; therefore, data interpretations are limited to the most obvious conclusions. Final conclusions will not be presented until the analysis of data is completed in September 1989. 48 refs., 25 figs., 4 tabs.

Teacher Lectures Given at UCRL During Summer of 1956

Description: In April of 1955 the Radiation Laboratory of the University of California sent out to 18 high schools in the Bay Area letters which said, in part, 'The object of this program is to help science teachers achieve some practical knowledge and experience in nuclear science by working with some of our basic research groups in physics and chemistry. In this way we believe that we can assist these teachers in their efforts to make their students more aware of the nature of atomic energy and help to prepare them for the impact of atomic energy in their future.'

A survey of available information on gas generation in tank 241-SY-101

Description: As a result of a concerted effort to determine the chemical and physical mechanisms underlying the generation and episodic release of gases from tank 241-SY-101, more commonly known as tank 101-SY, the Tank Waste Science Panel has been established at the Pacific Northwest Laboratory. Four of the members of this panel met to screen the available information on tank 101-SY and provide to the remaining members a shortened list of references that could be used to assess the mechanisms underlying the generation and episodic release of gases from tank 101-SY. This document is the result of this preliminary screening of information for the Tank Waste Science Panel and was provided to the Panel members at their first meeting. 14 refs., 3 tabs.
