Effects of Overpressures in Group Shelters on Animals and Dummies

Description: S>Relative biological hazards of blast were studied in two types of communal air-raid shelters during Shots 1 and 8. Dogs, restrained within the shelters during detonation, were studied pathologically and clinically for blast injuries. Two anthropometric dummies were test objects for displacement studies utilizing high-speed photography. Physical data included pressure vs time and air-drag determinations. During Shot 1, animals sustained marked blast damages (hemorrhages in lungs and abdominal … more

RADIOISOTOPE TECHNIQUES FOR CHEMICAL, PHYSICAL, AND INDUSTRIAL APPLICATIONS

Description: A laboratory manual is given consisting of 14 experiments designed to teach some of the basic fundamentals of the application of radioisotopes, and to introduce the principles of radioisotope technology. The majority of the experiments, while designed to be practical, are planned for scientists having little background in radiochemical and radioisotopc technology, and the remainder are outlined for more advanced personnel. The experiments include isotope production, sample preparation and half … more

The Gravimetric Determination of Tungsten in Uranium-Tungsten Alloys

Description: Tungsten in uranium--tungsten alloys is determined by precipitating the tungsten from a cold sulfuric acid solution using alpha -benzoinoxime and cinchonine as the precipitating agents. The precipitate is dgnited at 800 deg C and weighed as WO/sub 3/. Results of 94 determinations on known samples containing 20 to 40 milligrams of tungsten in the presence of 1 to 8 grams of uranium showed an average recovery of 100.1% with a standard deviation of 0.7%.

Analytical Program for Processing Stainless Steel Uranium Dioxide Reactor Fuel Elements

Description: Analytical programs have been described for uranium recovery processes for aluminum-uranium and zirconiumuranium reactor fuel elements. It is the purpose of this paper to describe the analytical program for the uranium recovery process involving stainless steel-uranium reactor fuel elements. The recovery process consists of a two step dissolution and the regular liquid-liquid solvent extraction using TBP in kerosene. Sulfuric acid is used to dissolve the stainless steel. As a result of the sulf… more

Spert Project Quarterly Technical Report, April-June 1962

Description: Static measurements of various nuclear core parameters were completed for the highly enriched plate-type Al-clad core to be used for the Spert I integral core destructive test program. Self-limiting power excursion tests were performed with initial asymptotic reactor periods in the range of 934 to 4.6 msec to establish the transient response of the core and to obtain data for extrapolation to shorter-period tests in which violent destructive effects are expected. For tests with periods shorter … more

Semi-Annual Summary Research Report in Chemistry for January-June 1957

Description: Heat capacity measurements of yttrium were made from 15 to 350 deg K. Lattice constants are given for rare earth-carbon systems. Thermal analyses were carried out on rare earth fluorides to determine their melting points. The extraction of fission products with silver is discussed. A study was made of the vertical distribution of both Zr and carbon in a sample of U-- Zr alloy prepared from U metal. The degree of immiscibility of U and rare earth metals was determnined, and the results are given… more

Some X-Ray and Fast Neutron Response Characteristics of Silver Metaphosphate Glass Dosimeters

Description: A study was conducted to determine the adequacy of silver metaphosphate glass as a dosimeter for gamma radiation coexistent with fast neutrons. The fast-neutron response in the energy region encompassing a major pcrtion of the fission spectrum was determined and a method of decreasing the photon-energy dependence was developed. The size of the dosimeter and reprcducibility of results make this system a useful addition to gamma -ray dosimetry. particularly for gamma rays coexistent with neutrons… more

Dry Bearing Endurance Test for the Service Machine: Experimental Gas-Cooled Reactor

Description: The concept of operating bearings and gears unlubricated in a helium environment was questioned as to fundamental soundness. Tests were made to determine if immediate gross failure occurs. A bearing of standard manufacture was operated in helium for 42 hr. A high degree of gradual wear was encountered. No gross or sudden failures were found. (W.L.H.)

Heat Capacity Studies of Uranium and Uranium-Fissium Alloys

Description: The heat contents of high-purity uranium and uranium-fissium alloys containing 3, 5, and 8 wt.% fissium were measured at temperatures from 0 deg C through their fusion temperatures. The total heat content above 0 deg C was determined by drop calorimetry and quantitative differential thermal analysis. The total heat content from 0 to 1200 deg C was found to be 16.1 plus or minus 0.3, 16.3 plus or minus 0.6, 16.3 plus or minus 0.6, and 16.4 plus or minus 0.4 kcal per equivalent gram atom, for the… more

Purex Process Performance With Short-Residence Contactors

Description: Recovery and purification were satisfactory in miniatarepilot-plant tests of the Purex first cycle with the solvent residing four seconds in each extraction stage. Decontamination factors for both zirconium-- niobium and ruthenium were greater than 10,000 with negligible crosscontamination of uranium and plutonium. The effects of the following on decontamination and plutonium partitioning were determined: irradiation level of the fuel, operating temperature, solvent saturation, accumulated expo… more

Thermal Cycling of Plutonium. Part I. Observations of the Physical Damage Resulting From Thermal Cycling Plutonium Through Its Low Temperature Phase Transformations

Description: Plutonium, thermally cycled through the low-temperature allotropic transformations, exhibited extensive physical damage. The physical damage was greater than that reported for any other metal or alloy. The extent of physical damage was determined by measurements of fluid displacement and the dimensional changes. The internal porosity was examined metallographically. Physical damage varied considerably, depending on the cycling conditions and the characteristics of the metal (particularly inclus… more
