Silicon web process development. Annual report
During this reporting period significant milestones have been met. A new barrier crucible design which consistently maintains melt stability over long periods of time has been successfully tested and used in long growth runs. The pellet feeder for melt replenishment was operated continuously for growth runs of up to 17 hours (a one day growth cycle). The liquid level sensor comprising a laser/sensor system was operated, performed well, and meets the requirements for maintaining liquid level height during growth and melt replenishment. An automated feedback loop connecting the feed mechanism and the liquid level sensing system was designed and constructed and, during the preparation of this report, operated successfully for 3 1/2 hours demonstrating the feasibility of semi-automated dendritic web growth. The web throughput task has resulted in a demonstration of wider good quality web as well as a demonstration of higher throughput rates. The accomplishments during the report period are described in detail. The economic analysis of the dendritic web process was updated. The sensitivity of the cost of sheet to variations in capital equipment cost and recycling dendrites was calculated; and it was shown that these factors have relatively little impact on sheet cost. An important finding was …

Hydrogeochemical and stream sediment reconnaissance basic data for Rapid City NTMS Quadrangle, South Dakota
Results of a reconnaissance geochemical survey of the Rapid City Quadrangle are reported. Field and laboratory data are presented for 417 groundwater and 477 stream sediment samples. Statistical and areal distributions of uranium and possible uranium-related variables are displayed. A generalized geologic map of the survey area is provided, and pertinent geologic factors which may be of significance in evaluating the potential for uranium mineralization are briefly discussed. Groundwater data indicate that the most promising areas for uranium mineralization are in the central portion of the quadrangle in the Pierre Shale. Three main clusters of groundwater samples with high uranium values occur here. Associated with the high uranium concentrations are high values for calcium, potassium, magnesium, strontium, and specific conductance. Stream sediment data indicate high concentrations of uranium are usually found in the Pierre Shale. Scattered samples occur in the Graneros Shale and in the Paleozoic and Precambrian units of the Black Hills. Arsenic, cobalt, and yttrium are associated with the areas of high uranium concentration. No areas are indicated with strong potential for uranium mineralization.

Experimental design for reflection measurements of highly reactive liquid or solid substances with application to liquid sodium. [LMFBR]
This technical report describes the experimental part of a program on thermal radiation properties of reactor materials. A versatile goniometer system with associated electronic components and mechanical instruments has been assembled. It is designed to measure spectral, specular reflectances of highly reactive liquid or solid substances over a spectral range of 0.3 ..mu.. to 9 ..mu.. and incidence angles of 12/sup 0/ to 30/sup 0/ off the normal direction. The capability of measuring reflectances of liquid substances clearly distinguishes this experimental design from conventional systems which are applicable only to solid substances. This design has been used to measure the spectral, specular reflectance of liquid sodium and preliminary results obtained are compared with those of solid sodium measured by other investigators.

Definition of requirements for geothermal power conversion system studies
Candidate power conversion systems and criteria for comparing these systems are listed. The elements of each conceptual design and standard approaches to equipment design are described. The methods used to calculate heat and mass balances and the data used in the calculations are described. The method used in developing the economics of each system is described and factors such as construction wage rates common to all systems are included. Standard methods for developing the conceptual designs and corresponding economics are defined so that the results of each system study can be readily compared to those of the others. The candidate conversion systems are: multistage flash/binary; two stage flash with scrubbing; total flow; multistage flash/direct contact (Bechtel patented process); four stage flash/binary; binary with direct contact heat exchangers; hybrid-flash/binary; hybrid-flash/total flow; and flash/dual cycle binary.

Stream sediment detailed geochemical survey for Date Creek Basin, Arizona
Results of the Date Creek Basin detailed geochemical survey are reported. Field and laboratory data are reported for 239 stream sediment samples. Statistical and areal distributions of uranium and possible uranium-related variables are displayed. A generalized geologic map of the area is provided, and pertinent geologic factors which may be of significance in evaluating the potential for uranium mineralization are briefly discussed. Based on stream sediment geochemical data, significant concentrations of uranium are restricted to the Anderson Mine area. The 84th percentile concentrations of U-FL, U-NT, and U-FL/U-NT combined with low thorium/U-NT values reflect increased mobility and enrichment of uranium in the carbonate host rocks of that area. Elements characteristically associated with the uranium mineralization include lithium and arsenic. No well defined diffusion halos suggesting outliers of similar uranium mineralization were observed from the stream sediment data in other areas of the Date Creek Basin. Significant concentrations of U-FL or U-NT found outside the mine area are generally coincident with low U-FL/U-NT values and high concentrations of zirconium, titanium, and phosphorus. This suggests that the uranium is related to a resistate mineral assemblage derived from surrounding crystalline igneous and metamorphic rocks.

Flux and Power Distributions for the SM-2 Reference and Critical Experiment Cores
A detailed analysis was made of the power distributions in the SM-2 experimental core at 68 deg F and the SM-2 reference core at 510 deg F. This analysis supersedes the power distribution calculations presented in APAE No. 69. The calculated distributions for the experimental core were normalized to measured data wherever possible in order to obtain corrections factors for application to the reference core. The over-all power distributions were calculated by synthesis of one-dimensional axial calculations with twodimensional radial calculations. The variation of the power distribution with fuel burnup is also presented. In order to improve the agreement between measured and calculated axial power distributions, flux-weighting the nuclear parameters in the rods-in and rods-out regions was investigated. (auth)

Commingled uranium-tailings study. Volume I. Plan for stabilization and management of commingled uranium-mill tailings
This report, prepared in accordance with Section 213 of Public Law 96-540, presents a plan for a cooperative program to provide assistance in the stabilization and management of commingled uranium mill tailings. The report is organized in two volumes, a summary report (Volume I) and a companion technical report (Volume II). Contents of Volume I are: summary; background; amount and condition of the tailings; regulatory requirements; stabilization cost estimates; costsharing alternatives; administrative options and plan implementation; standards and regulations. The DOE recommends that the standards and regulations for tailings stabilization be relaxed and that any program of stabilization be limited to prevention of migration and erosion of the tailings and inadvertent exposure to them. The plan presented here shows the effort and costs that would be incurred if the government were to implement such a plan. The Department makes no recommendation as to the advisability of actually implementing legislation authorizing an assistance program, and stands ready to respond to comments on the plan by Congress, other government agencies, or interested parties.
