Thermal evaporation of a variety of simulated pore waters from the region of Yucca Mountain, Nevada, produced acidic liquids and gases during the final stages of evaporation. Several simulated pore waters were prepared and then thermally distilled in

Dissolution rates of nickel powder in pH 5 acetate buffers were observed to be an effective indicator of the thickness of the oxide layer on the surface of the nickel particle. Tests on powders pre-cleaned with acid or pre-oxidized in air demonstrate

Chemical analyses, magnetization, Mossbauer spectrum, and x-ray diffraction measurements were made on solids removed from tap water by means of membrane filters. The taps from which this water was obtained had previously been unused for prolonged per

Chemical cleaning methods were developed for the removal of leachable hazardous cyanide and fluoride impurities from spent carbon liners used in aluminum metal production. Cyanide can be destroyed by treatment with NaOCl solutions at near-neutral pH.

Samples of Alloy 22 were tested in solutions containing various anions in order to determine their effect on the corrosion of the alloy. It was found that Alloy 22 is relatively corrosion resistant in HCl and HNO3 at pH 1 and 160°C (general corrosio

Titanium Grade 7 (Ti-7) was tested for both general and local corrosion in environments consisting of fluoride and chloride salts added to simulated groundwaters. Tests were conducted on both U-bends and disks in order to determine the extent of corr

The effects of chloride, sulfate, and nitrate on the fluoride ion local attack of Ti-Grade 7 (Ti-7: UNS R52400) were investigated. It was observed that a chloride: fluoride ratio of as high as 10 : 1 by mole was necessary to produce visible severe at

The effect of Pb, Hg, thiosulfate and sulfide on the corrosion of Alloy 22 was studied. In solutions of 1000xJ13 groundwater doped with these contaminants, disks and U-bend specimens exhibited general corrosion and pitting at pH 1, and some dissoluti

Both concentrated and dilute simulated solutions of saturated J13 and unsaturated UZ pore water were concentrated through distillation of the solutions under atmospheric pressure. It was observed that condensed vapors from the pH of J13 waters steadi
