From abstract: "The development, design, specification, and manufacture of special-purpose thermocouples sheathed in stainless steel for use in nuclear reactors are described. In connection with this work, a three element cable for transmitting the signal from neutron-flux measuring devices was developed."

From abstract: "Performance data were obtained for the TNX replacement evaporator when operated within the limits imposed by a new control system. This system was designed to avoid conditions which might lead to a repetition of an earlier explosion due to inclusion of organic material in the uranyl nitrate-nitric acid system, which was heated to elevated temperature. The true heat transfer coefficient was found to be 280 BUT/hr-ft2-ºF for all concentrations of solutions to be evaporated in the plant, and will allow operation at design capacities."

From abstract: "This report gives a detailed account of the corrosion test work carried out by the Engineering Research Laboratory on the behavior of materials of construction in the hydrogen sulfide-water system. Results developed during the period from October 1950 through November 1954 are included."

From abstract: "Equations are derived from the discontinuity stress in a cylindrical tank that is mounted vertically on a header and is open at the top. The analysis includes a derivation of equations for the prediction of the deflection and slope of the header by relating the strain energy in bending a circular plate to the strain energy in bending the header. The stresses that result from pressure and temperature are included in the analysis."

From abstract: "An instrument is described which measures the uranium content of a 0.080-inch thick plate of uranium-aluminum alloy. The content is measured by gamma-ray transmission to an accuracy of +/- 0.0006 gram per square centimeter over the range of 0.085 to 0.115 gram per square centimeter of contained uranium."

From abstract: "A pump-mix mixer-settler was demonstrated to have an overall efficiency greater than 90 per cent for the extraction of uranyl nitrate from tributyl phosphate at total flow rates up to 45 gallons per minute. Phase separation was satisfactory at 45 gallons per minute, at which flow rate the residence time in the settlers was 1-1/2 minutes. It appeared possible that a throughput approaching 60 gallons per minute would be operable although at an over-all efficiency of less than 90 per cent. The tests were made on a three-stage unit, but the data can be extrapolated to multistage units. The effects of design of the impeller and mixing section, impeller speed, flow rates and ratios, and operating temperatures were studied. The mechanical performance and dependability of the unit were excellent."

From abstract: "A tester was developed to detect nonbonded areas between the cladding and the core of hollow slugs. These slugs are one inch in diameter and eight inches long, and have a 3/8 inch axial hole. The tester employs an ultrasonic detector previously developed at the Savannah River Laboratory. A transducer 5/16 inch in diameter was developed to pass down the inside of the slug and a mechanical feeder was constructed to provide an automatic inspection cycle."

From abstract: "A tester, utilizing eddy currents, was developed to detect inclusions and voids in aluminum cans. The sensing element is a small probe that does not touch the can under inspection. An experimental feeder, developed along with the tester, permits the automatic inspection of one can per minute."

From Abstract: "Fuel tubes of enriched uranium-aluminum alloy were melted to various degrees of severity in the SPERT I reactor as a part of a program to evaluate reactor operating hazards. The heat flux encountered during the tests ranged from 200,000 to 650,000 pcu/(hr)(ft^2). The time required for the metal temperature to reach the melting point from the time when burnout began varied from 1.3 to 4.9 seconds. During these tests, pressure pulses were produced at a frequency of about one per second with peaks of about 150 psi."

Technical report. From Abstract : "Spark counters of the wire plate type are rugged and simple, and their sensitivity is directly proportional to the specific ionization of incident particles. Spark counters are insensitive to beta and gamma radiation but readily respond to alpha particles. With a suitable converter, the spark counter can also be employed as a neutron counter. Spark counters thus appear to be very good candidates for the measurement of neutron flux at reactor startup, where the high background of gamma radiation can be troublesome to other types of counters. A spark counter of cylindrical geometry was built and shown to have adequate sensitivity and stability for such duty."

Technical report. From Abstract : "Plutonium (principally Pu238) was separated from neptunium, and both the plutonium and neptunium were purified from fission products and cations by a three-cycle anion exchange process."
