This paper describes a means of determining tritium oxides in urine relying upon the production of acetylene from the active water with subsequent measurement of the ionization caused by the tritium beta particle.

Welding is used to fabricate titanium and titanium-alloy components for air-frames, Jet engines, missiles, and chemical equipment. Annong the most important considerations in adapting titanium and its alloys to welded components is to use proper welding procedures and to select alloys that have the required weld-joint properties. The chemical and metallurgical characteristics that affect the selection of welding processes and alloys are discussed. Also, information is presented on surface preparation, welding procedures, and quality control. In addition, detailed data on the mechanical properties of welded joints in the commercial grades of titanium and titanium alloys and how these properties are affected by heat treatment and elevated temperatures are presented.

On June 23, 1947, a hole was discovered in the earthen fill near the T Plant R-19 stairwell directly above the path followed by the underground waste lines from the canyon. Jetting of all canyon wastes to the 241 Buildings was stopped and the canyon process shut down. This report discusses repair and characterization procedures for the soils and waste line pipe.

Data acquired from sampling the Columbia River water September 1, 1943, is presented. The waster was analyzed for turbidity, ph value, chemical composition, and suspended matter.

This document serves to record pertinent information regarding detection and repair of a water leak in Process Tube No. 3169-F in the F File and subsequent steps necessary to remove the water from the pile in order to return to normal level.

Progress was reported from the 300, 100, and 200 Areas. It covered the X pile, aluminium corrosion, graphite purity, fuel element fabrication, bismuth phosphate extraction and decontamination processes, waste disposal from bismuth phosphate processing, control rod systems for Site W, shielding problems at the Site W separation plant, fuel element failure detection, power distribution in the Clinton pile, reactor instrumentation for Site W.

The radio-active xenon and iodine evolved during the dissolution of the uranium may present a health hazard within certain areas around the base of the stack through which the dissolver off-gases are discharged. Since the concentration of these elements in the uranium metal is directly proportional to the power of the pile* and is related to decay period of the metal in accordance with their half-lifes, the maximum rate of discharge of these elements from the stack at H.E.W. can be estimated form existing Clinton data. The required wind dilution to reduce the discharging activation to tolerance levels can then be calculated. The time with respect to the start of the metal dissolution at which the maximum rates of discharge will be attained can also be roughly estimated form existing Clinton data. 3 figs., 3 tabs.

A report of seven stack emissions of I-131 at the T and B plants, detailing the relationship between cooling times and dilution factors for the safe emission of the isotope. From the stack sampling, personal exposure limits for an eight and nine hour day are calculated. The effect of atmospheric conditions appears to be negligible, although periods of atmospheric stagnation may have an effect on the I-131 concentration. Environmental effects are minimized by increasing the cooling times of the isotope charge. Downdrafts near the stack emissions during low dilution increase the radiation level, but do not pose any inhalation hazard.
