Ground Level Concentrations in the Vicinity of a 185 ft Stack (open access)

Ground Level Concentrations in the Vicinity of a 185 ft Stack

Field tests were conducted to measure short-period pollutant concentrations at several stack heights during conditions of marked atmospheric instability and low wind speeds. The source was a mechanical smoke generator located at the 185-ft level of a tower.

Slug Manipulator (open access)

Slug Manipulator

A manipulator designed to support an irradiated slug at the bottom of the viewing basin, so that an operator could view it through a binocular telescope and be able to see all surfaces, was designed. Hydraulic power, using water, operates the manipulator and gears.

Corrosion of Stainless Steels in Purex Acid Concentrators (open access)

Corrosion of Stainless Steels in Purex Acid Concentrators

The corrosion resistance of four types of austenitic stainless steels to Purex process first and second acid concentrator bottoms was determined. Although the compositions of the two solutions were very similar, tests in simulated solutions of both compositions were conducted to strengthen the basis for the conclusions which were to be made.

Final Report:  Production Test No. 305-2-N Experimental Results Obtained From Test Pile Reactivity Measurements on Plutonium (open access)

Final Report: Production Test No. 305-2-N Experimental Results Obtained From Test Pile Reactivity Measurements on Plutonium

Measurements were taken to provide experimental evidence for determining the feasibility of a proposed method for converting Pu240 to 241 by exposing shielded plutonium to selectively transmitted pile neutrons.

Corrosion Effects of Lowering the pH in TBP Waste Storage Tanks (open access)

Corrosion Effects of Lowering the pH in TBP Waste Storage Tanks

Large savings in waste storage space may be realized by lowering the pH at which TBP waste is stored. Additional savings in neutralizing chemicals and operating time would also increase the monetary gain from such a process change. However, before such a change could be made, the corrosive effect of TBP waste at a lower pH on the mild steel waste storage tanks had to be determined.
