A series of maps have been compiled to document the structure and stratigraphy of the sediments underlying the high-level radioactive waste storage tank farms located within the Energy Research and Development Administration Hanford Reservation. The primary purpose of these maps is to provide basic geologic information to be utilized to evaluate the impact of suspected and confirmed tank leaks.

During operation of the prototype FFTF sodium pump, it is necessary to know the position of the pump shaft relative to the sodium-lubricated hydrostatic bearing journals. Performance of the Kaman proximity measurement system was known to be affected by the type of media between the gap to be measured. Since Kaman Sciences Corp. did not have liquid sodium testing capabilities, LMEC was requested to evaluate a spare prototype system. Determination of the sodium performance characteristics of the Kaman proximity systems was a necessary requisite for use of four prototype systems in the FFTF prototype pump test program.

The preliminary analysis is described in a study of practical cycles for geothermal power plants. The analysis is based on three different brines whose temperatures and composition span the range that is of practical interest for power generation. Only two kinds of cycles were considered in the analysis - the steam turbine cycle and the binary cycle, in which energy from the geothermal fluid is transferred to a secondary working fluid in a closed Rankine cycle. The performance of several condidate working fluids has been investigated, and the most attracive binary cycles have been selected for the various resource conditions. The results show that if brine is utilized directly in the primary heat exchange process with the secondary working fluid, the binary cycle is potentially better in terms of resource utilization than a dual flash steam turbine cycle. However, if the brine is flashed to steam and the steam is used for the heat exchange process, the steam turbine cycle will produce more power per pound of brine flow. Preliminary turbine designs have been formulated for steam and also for the most promising working fluids in the secondary or binary cycle. For all cycle configurations at least 50 MW of …

Sodium-cladding chemical interaction has been studied on fuel pins clad with 20% cold worked type 316 stainless steel and irradiated in the EBR-II at temperatures up to 705/sup 0/C and for exposures to 5300 hours. The measured corrosion rate of the cladding surface immediately above the top of the fuel column was 12.5 ..mu..m per year at 690/sup 0/C. The loss of Ni at 700/sup 0/C resulted in the formation of a ferrite layer approximately 5 ..mu..m thick. A zone depleted in Ni and Cr extends into the austenite from the ferrite-austenite interface an additional distance of approximately 15 ..mu..m. No large changes in volumetric average carbon or nitrogen were observed.

Detailed wind energy assessment from the available wind records, and evaluation of the application of wind energy systems to an existing electric utility were performed in an area known as the Texas Panhandle, on the Great Plains. The study area includes parts of Texas, eastern New Mexico, the Oklahoma Panhandle and southern Kansas. The region is shown to have uniformly distributed winds of relatively high velocity, with average wind power density of 0.53 kW/m/sup 2/ at 30 m height at Amarillo, Texas, a representative location. The annual period of calm is extremely low. Three separate compressed air storage systems with good potential were analyzed in detail, and two potential pumped-hydro facilities were identified and given preliminary consideration. Aquifer storage of compressed air is a promising possibility in the region.

A number of design changes were considered to improve heat transfer characteristics of the WESF capsule. This capsule was evaluated in a design concept for use as a heat source in a helium-working fluid, Stirling heat engine. Throughout the study a heat block concept was used. The helium was assumed to be at 1200/sup 0/F and 200 atm. The upper temperature limit at the fuel-metal interface was assumed to be 800/sup 0/C because of material compatibility considerations. A 0.6-in. thick outer can was considered since it may be required for impact resistance and high pressure accident environments. The modifications considered were: (1) filling all gaps with helium rather than air, (2) filling gaps with powdered metal, and (3) adding a third can to the existing capsule. Also, enhancement of emissivity on metal surfaces was considered as a possible modification.

There has been considerable need for neutron radiation units with high neutron yield. Sources of various types have been used for this purpose for many years, but have lacked the intensity and volume, with level flux, for larger sample irradiation. While the research reactor can produce desirable neutron flux, the operation is rather costly. A neutron multiplier has been designed using a subcritical lattice of highly enriched uranium rods with a central cylindrical flux trap. This lattice unit was loaded at the Critical Mass Laboratory to study aspects of criticality including temperature, voids, and added material. Data from these experiments are presented.

The effects of lateral mass efflux with prescribed temperature and velocity on vertical free convection boundary layers in a saturated porous medium at high Rayleigh numbers are studied analytically. Within the framework of boundary layer theory, similarity solutions are obtained for the special case where the prescribed temperature and velocity of the fluid vary as x/sup lambda/ and x/sup (lambda-1)/2/ respectively. The effects of mass efflux on surface heat transfer rate and boundary layer thickness are shown. Application to warm water discharge along a well or fissure to an aquifer of infinite extent is discussed.

The axisymmetric buoyancy-induced groundwater flow adjacent to horizontal impermeable surfaces with wall temperature being a power function of radius is discussed in this paper. With the boundary layer simplifications, the governing non-linear partial differential equations can be transformed into a coupled pair of non-linear ordinary differential equations with two-point boundary conditions that can be integrated numerically by established techniques. Simple algebraic expressions for boundary layer thickness and heat transfer rate are obtained. Applications to free convective flow in a liquid-dominated geothermal system at high Rayleigh number are discussed.

Growth rates for the denitrifying bacteria Pseudomonas Stutzeri were studied to minimize the time necessary to start up a bacterial denitrification reactor. Batch experiments were performed in nine 250-ml Erlenmeyer flasks, a 7-liter fermentor, and a 67-liter fermentor. All reactors maintained an anaerobic environment. Initial microorganism inoculum concentration was varied over four orders of magnitude. Initial nitrate and substrate carbon concentrations were varied from 200 to 6000 ppm and from 56 to 1596 ppm, respectively, with a carbon-to-nitrogen weight ratio of 1.18. In all experiments, except those with the highest initial substrate-to-bacteria ratio, no growth was observed due to substrate depletion during the lag period. In those experiments which did exhibit an increase in bacterial population, growth also stopped due to substrate depletion. A model simulating microbe growth during the induction period was developed, but insufficient data were available to properly adjust the model constants. Because of this, the model does not accurately predict microbe growth. The metabolism of Pseudomonas Stutzeri was studied in detail. This resulted in a prediction of the denitrification stoichiometry during steady state reactor operation. Iron was found to be an important component for bacterial anabolism.

The spectra, angular distribution, and polarization functions of synchrotron radiation are tabulated in parametric form. Numerous graphs of the functions are included, and these can be used for rapid estimation of photon flux as a function of the various parameters. The extended synchrotron radiation source is described, and the exact, but unintegrable, equations are derived. Properties of this source depend upon at least nine parameters. An approximation of the source accurate enough for estimating flux in optical instruments is developed. Power and power density in the radiation beam are described and convenient approximations are developed. Simple optical transformations are used to illustrate some of the important properties of the extended source.
