Book Description
The Energy Information Administration's (EIA) Uranium Resource Assessment Data (URAD) System contains information on potential resources (undiscovered) of uranium in the United States. The purpose of this report is: (1) to describe the work carried out to maintain and update the URAD system; (2)to assess the 1991 U.S. uranium potential resources in various cost categories; and (3) to describe the progress that has been made to automate the generation of the assessment reports and their subsequent transmittal by diskette.

Book Description
For 1992, estimates of US undiscovered uranium resources were generated using revised economic index values (current to December 1992) in the Uranium Resources Assessment Data (URAD) System's cost model. The endowments associated with the Estimated Additional Resources (EAR) and Speculative Resources (SR) values for all regions are unchanged from the 1991 values. Although higher 1992 indexes resulted in increased costs, the mean values for the $30-, $50-, and $ 100-per pound U308 forward-cost EAR category resources for 1992 show no significant changes when compared to the values in 1991. The mean values for the $30-, $50-, and $100-per pound U3O forward-cost SR forward-cost category show decreases of 4, 3, and 1 percent, in the three categories respectively. Under the Memorandum of Understanding (MOU) between the Energy Information Administration (EIA), US Department of Energy, and the US Geological Survey (USGS), US Department of the Interior, the USGS develops estimates of uranium endowment for selected geological environments in the United States. New estimates of endowment are used to update the URAD System that is maintained for the EIA by the USGS. Endowment estimates were added for the solution-collapse breccia pipe uranium deposits in the Grand Canyon region in 1989 and for young surficial uranium deposits in the Flodelle Creek area in Washington in 1991. Estimates of uranium endowment for roll-front uranium deposits in northwestern Nebraska and adjacent states are nearly completed and will be added in 1994. Assessment of undiscovered uranium endowment in new areas by the USGS will be discontinued in FY 1995 due to phasing out of the uranium resources program in FY 1994. Improvements to the URAD System included automating the procedures necessary to generate the assessment reports. Data retrieval from the URAD System can now be performed using dBase IV version 1.5 data base management system.

Book Description
Under the Memorandum of Understanding (MOU) between the EIA, US Department of Energy, and the US Geological Survey (USGS), US Department of the Interior, the USGS develops estimates of uranium endowment for selected geological environments in the United States. New estimates of endowment are used to update the Uranium Resources Assessment Data (URAD) System which, beginning in 1990, is maintained for EIA by the USGS. For 1989, estimates of US undiscovered resources were generated using revised economic index values (current to December 1989) in the URAD system's cost model. The increase in the estimates for the Estimated Additional Resources (EAR) and Speculative Resources (SR) classes resulted primarily from increases in the estimates of uranium endowment for the solution-collapse, breccia-pipe uranium deposit environment in the Colorado Plateau resource region. The mean values for $30-, $50-, and $100-per-pound U3O forward-cost categories of EAR increased by about 8, 48, and 32 percent, respectively, as compared to 1988. Estimates of the 1989 undiscovered resources in the SR class also increased in all three forward-cost categories by 10, 5, and 9 percent, respectively. The original cost equations in the URAD System were designed to cover drilling costs related to extensive flat-lying tabular ore bodies. The equations do not adequately treat drilling costs for the smaller areas of vertical breccia pipe uranium deposits in the Colorado Plateau resource region. The development of appropriate cost equations for describing the economics of mining this type of deposit represents a major new task. 12 refs., 4 figs., 5 tabs.
