Nuclear waste-form risk assessment for US Defense waste at Savannah River Plant. Annual report FY 1981

Description: Savannah River Plant has been supporting the Lawrence Livermore National Laboratory in its present effort to perform risk assessments of alternative waste forms for defense waste. This effort relates to choosing a suitable combination of solid form and geologic medium on the basis of risk of exposure to future generations; therefore, the focus is on post-closure considerations of deep geologic repositories. The waste forms being investigated include borosilicate glass, SYNROC, and others. Geolo… more

Energy and land use

Description: This report addresses the land use impacts of past and future energy development and summarizes the major federal and state legislation which influences the potential land use impacts of energy facilities and can thus influence the locations and timing of energy development. In addition, this report describes and presents the data which are used to measure, and in some cases, predict the potential conflicts between energy development and alternative uses of the nation's land resources. The topi… more

Groundwater chemistry of a nuclear waste reposoitory in granite bedrock

Description: This report concerns the prediction of the maximum dissolution rate for nuclear waste stored in the ground. That information is essential in judging the safety of a nuclear waste repository. With a limited groundwater flow, the maximum dissolution rate coincides with the maximum solubility. After considering the formation and composition of deep granite bedrock groundwater, the report discusses the maximum solubility in such groundwater of canister materials, matrix materials and waste elements… more

Leaching behavior of glass ceramic nuclear waste forms

Description: Glass ceramic waste forms have been investigated as alternatives to borosilicate glasses for the immobilization of high-level radioactive waste at Pacific Northwest Laboratory (PNL). Three glass ceramic systems were investigated, including basalt, celsian, and fresnoite, each containing 20 wt % simulated high-level waste calcine. Static leach tests were performed on seven glass ceramic materials and one parent glass (before recrystallization). Samples were leached at 90/sup 0/C for 3 to 28 days… more

DARTAB: a program to combine airborne radionuclide environmental exposure data with dosimetric and health effects data to generate tabulations of predicted health impacts

Description: The DARTAB computer code combines radionuclide environmental exposure data with dosimetric and health effects data to generate tabulations of the predicted impact of radioactive airborne effluents. DARTAB is independent of the environmental transport code used to generate the environmental exposure data and the codes used to produce the dosimetric and health effects data. Therefore human dose and risk calculations need not be added to every environmental transport code. Options are included in … more

Validation of predictive models for geologic disposal of radioactive waste via natural analogs

Description: The incorporation of toxic or hazardous material in the earth's crust is a phenomenon not unique to radioactive waste burial. Useful insights on the environmental transport and effects of underground toxic or radioactive material can be derived from comparative analysis against natural (mineral) analogs. This paper includes a discussion of the background and rationale for the analog approach, a descripton of several variations of the approach, and some sample applications to illustrate the conc… more

Geotechnical aspects of investigations at Stripa on radioactive waste isolation

Description: Access to a granitic rock mass in an iron ore mine in Sweden has provided a unique opportunity for a series of investigations on problems involved in geologic storage of radioactive waste. Important results have been obtained that would not have emerged if these experiments had not been carried out underground at depths comparable with those envisaged for an actual repository. It was observed that as the rock mass was heated, the temperature variations over time and space could be reasonably we… more

Apparatus for the measurement of radionuclide transport rates in rock cores

Description: An apparatus and procedure for the study of radionuclide transport in intact rock cores are presented in this report. This equipment more closely simulates natural conditions of radionuclide transport than do crushed rock columns. The apparatus and the procedure from rock core preparation through data analysis are described. The retardation factors measured are the ratio of the transport rate of a non-retarded radionuclide, such as /sup 3/H, to the transport rate of a retarded radionuclide. Sam… more

Models and criteria for waste repository performance

Description: A primary objective of the Waste Management Program is to assure that public health is protected. Predictive modeling, to some extent, will play a role in assuring that this objective is met. This paper considers the requirements and limitations of predictive modeling in providing useful inputs to waste management decision making. Criteria development needs and the relation between criteria and models are also discussed.

Radiological assessment of the decontamination and decommissioning of a small-scale fuel-reprocessing plant

Description: Decontamination and decommissioning (D and D) of surplus radiological facilities is becoming a major concern as buildings built during the 1940's and 1950's reach the end of their useful lives. Prior to the start of a D and D project, a detailed radiological characterization of the facility is required to determine the nature and extent of residual contamination. The Oak Ridge National Laboratory (ORNL) has recently begun such a characterization of Building 3505, originally called the Metal Rec… more

In-situ high-resolution gamma-spectrometric survey of burial ground-monitoring wells

Description: In situ high resolution gamma-ray spectrometry with an intrinsic germanium detector assembly of special design surveyed the burial ground monitoring wells to locate and identify gamma emitters that may have migrated from the burial trenches toward the water table. Gamma-ray spectra were acquired as a function of depth in each well and recorded on magnetic tape. These spectra were reduced by a series of computer programs to produce count rate versus depth profiles for natural and man-made activi… more

Saturated-column leach studies: Hanford 216-Z-1A sediment

Description: A previous laboratory study indicated that Pu and Am in the waste discharged to the crib would not be sorbed on the sediment but migrate with the waste solution. Field study of the TRU distribution beneath the crib support the conclusions of the laboratory study. The current laboratory study indicates that waste-sediment interactions have altered the waste, resulting in the retention of almost all of the Pu and most of the Am on the sediment tested. Batch leaching study results, in agreement wi… more
