To compensate for the potential for overly conservative estimates of risk using standard US Environmental Protection Agency methods, an uncertainty analysis should be performed as an integral part of each risk assessment. Uncertainty analyses allow one to obtain quantitative results in the form...

DOE facilities handling special nuclear material are required to comply with DOE Order 5633.3, which addresses various aspects of nuclear material accounting. In particular, it requires that control limits be calculated for nuclear material inventory differences. These requirements and methods...

This report provides background information for the Bonneville Power Administration (Bonneville) in its efforts to quantify the environmental externalities associated with new electricity resources. A more detailed companion document has been provided to Bonneville for internal use. This report...

This report presents guidelines for evaluating uncertainty in mathematical equations and computer models applied to assess human health and environmental risk. Uncertainty analyses involve the propagation of uncertainty in model parameters and model structure to obtain confidence statements for...

The disposal of the waste stored in single-shell tanks at the Hanford Site is recognized as a major environmental concern. A comprehensive program has been initiated to evaluate the various alternatives available for disposal of these wastes. Theses wastes will be disposed of in a manner...

To help integrate activities in the environmental restoration and waste management mission of the Hanford Site, the Hanford Integrated Planning Project (HIPP) was established and funded by the US Department of Energy. The project is divided into three key program elements, the first focusing on...

This paper describes statistical software developed at the Savannah River Site (SRS) to analyze event time of occurrence data extracted from fault tree data banks and/or user defined input data files. Five different distributions can currently be fit to the empirical data: normal, lognormal,...

Purpose of the audit was to determine whether the Department's conditional commitment to UltraSystems, Inc. (UltraSystems) was in compliance with the Geothermal Energy Research, Development and Demonstration Act of 1974 and applicable regulations. It was found that the loan guaranty conditional...

This paper presents an assessment of the radiation dose to the world population and the associated potential health effects from three scenarios of /sup 14/C releases by the nuclear industry between 1975 and 2020. Measures of health impact are derived from source terms through the use of a...

This manual contains the Radiation Control Standards'' and Radiation Control Procedures'' at Hanford Operations which have been established to provide the necessary control radiation exposures within Irradiation Processing Department. Provision is also made for including, in the form of...
