Abstract: "Recent request for new sites has prompted an overall review of the Pahute Mesa area. The criteria used in this review are that the geology must be favorable and that horizontal spacing of emplacement holes being developed should be 2.5 to 3 times hole depth. The review shows that current emplacement requirements have exhausted available explored sites and have effectively eliminated 90 percent of the blocks of ground geologically favorable for chambered sites."

From Introduction: "This report contains the results of a research study on the "Value of Desalted Water for Irrigation" undertaken in January 1967 by the Bureau of Reclamation and the Saline Water, United Sates Department of the Interior. The objectives of the study were: a. To determine, through application of desalting techniques, the costs and benefits associated with the progressive decreases in the salinity of irrigation water supplies. b. To identify the possible means of introducing desalted water into irrigation supply systems. To relate current desalting technology to potential applications in agriculture."

Summary: "This report provides data on the alluvial aquifer of the Lower Mississippi Valley in the area between Cape Girardeau, Missouri, and Port Gibson, Mississippi. Maps are presented of the Tertiary surface on which the alluvial aquifer rests as well as the geology of this surface and the areas where hydrologic recharge to the alluvial aquifer may occur. A set of piezometric-surface maps, together with hydrographs of observation wells, river stages, precipitation rates, and data on the hydrologic properties of the alluvium, makes it possible to calculate changes which take place in the aquifer. Further data are presented on the chemical quality of groundwater. The relevance of these data to engineering problems is discussed" (p. ix).

From Introduction: "This Annual Report on the maintenance and operation of Brackish Water Conversion Demonstration Plant No. 3, located in Webster, South Dakota, presents the Plant Maintenance and Operational History and the Technical, Economic and Administrative evaluations of the Plant's operation during the period 1 July 1963 through 30 June 1964. This Report is prepared in compliance with Management and Operations Contract No. 14-01-001-225 dated 2 October 1961."

When the Brookhaven AGS started operation in the summer of 1960 very little experience with targeting in strong focusing proton synchrotrons was available. While it was evident that targeting techniques would differ markedly from those used in weak focusing machines, only actual running experience would set the proper parameters for a truly satisfactory targeting system. It was, therefore, an advantage that temporary targeting devices were used initially. Work on a more permanent system was not started until the summer of 1961, and the first component of the system installed in January 1962. While further refinements are still continuing the essential features of this targeting system have now sufficiently proven themselves in actual operation to remain unchanged. This system in its present form is the subject of the first portion of this paper.

The BNL cold neutron facility has been used to obtain inelastic scattering cross section data from three first-row transition elements, titanium, vanadium, and nickel, and a random binary alloy Ti.67-Zr.33. From the data, we have computed vibrational frequency distributions exhibit peaks corresponding to major critical points. A comparison of the distributions from the different samples leads to the following conclusions: 1) The shape of the frequency distributions of the b.c.c. metal (V) and f.c.c. metal (Ni) are remarkably similar, the relative positions of the critical points being the same for both; 2) The frequency distribution of the h.c.p. metal (Ti), which has two atoms per primitive cell, shows structure corresponding to acoustical and "optical" modes of vibration; 3) The titanium-zirconium alloy has the h.c.p. structure, and its experimental frequency distribution is similar to that of titanium, except at low frequencies where alloying with the heavier mass zirconium atoms tends to smear out the peaks corresponding to acoustical modes. Measured frequency distributions were obtained for the titanium-zirconium alloy slightly above and below the critical temperature for the phase transition to b.c.c. structure. The frequency distributions in the two phases are different, the most striking feature being a shift of the high …

The subject of this paper is the experimental and technical aspects of the measurements of nuclear resonance parameters. I will confine my remarks to those reactions induced by low energy neutrons, i.e. neutrons of less than approximately 100 kilovolts. The bulk of these measurements have been performed by neutron time-of-flight techniques, and I will direct my attention to these techniques. The first half of this discussion will concern the apparatus with which these measurements are made; the second part will be a discussion of the various experiments by which these parameters are measured, with an emphasis in both areas of discussion on relatively recent developments in the field.

"The performance of the Model I electrostatic precipitator sampler in recent field and laboratory tests is described and discussed. Two of the four precipitator-bearing balloon flights during this interval reached the floating altitude of approximates 105,000 feet, and the precipitator operated efficiently on both. One sample was collected at the nominal design flowrate of approximates 100 cfm, and the second at approximates -200 cfm. Comparison of the deposition profiles of the stratospheric samples with those obtained under controlled conditions in the altitude chamber indicates that the field samples were collected with >90% efficiency. The laboratory tests also showed that the performance capability of the precipitator improves with increasing precipitator current, and with increasing altitude. One of the above balloon flights carried two Model A-I altimeters with recorder outputs. The two records were identical within plus or minus 250 feet. In addition, variations in altitude indications were consistent with the less sensitive aneroid barocoder measurements from the same flight. A revised Model A-I altimeter with a telemeterable output signal has been designed and constructed. The frequency of the signal is a function of the altitude. A preliminary design concept for a flowmeter with negligible flow resistance is described. It would utilize …

100% recovery of uranium from pyrolytic carbon-coated spheroids of uranium dicarbide has been accomplished by an aqueous electrolytic process at the small scale laboratory level. This result was obtained in a system which circulated 1 molar nitric acid through a thin bed of the spheres. The bed was supported between a glass frit and the anode, with which the bed was in contact. The anode was a spiral of platinum wire; the cathode was a grid of titanium wire. Current density was about 0.2 amp/cm2 based on geometric surface area calculated from the average particle size of 150 microns. Initial flow rate was about 1.3 ml/cm2/sec. Reaction temperature was 72-82°C; time was 15 hours. At 1/5 the above current density and at the same temperature recovery was smaller and was independent of concentration of nitric acid over the range 1-4 molar; also recovery in 1 molar ammonium nitrate was about the same as in 1 molar HNO3. About a 100-fold increase in recovery was obtained by going from a convection stirred cell at 90°C to the pumped type of cell at 54°C using ammonium nitrate as the electrolyte.
