DENSJT: statistical shell-model level density computer code description and user's manual. [In FORTRAN for CDC Cyber-70 computer]

Description: The FORTRAN code DENSJT described here is constructed to calculate the appropriate moments and dimensions needed in describing the Gaussian level density for fixed values of the total angular momentum (J) and isobaric spin (T = T/sub 0/). The input for this code is the same as in the usual shell-model codes, namely, the single-particle orbital properties and the antisymmetric two-body matrix elements. To calculate the moments for fixed values of the angular momentum (J) a method described by Gi… more

Natural gas massive hydraulic fracture research and advanced technology project. Quarterly report: February 1977--April 1977

Description: Two field experiments were conducted with the surface electrical potential measurement system. The first was an MHF experiment with G.P.E. (Gas Producing Enterprises) on March 15 south of Vernal, Utah. This fracture was a joint ERDA-industry funded experiment. Approximately 640,000 gallons of fluid and 1.1 million pounds of proppant were injected into multilayered gas pay zones from a depth of 6500 feet to 8000 feet. This analysis of the data has produced several new and different concepts rela… more

Laser fusion hybrid reactor systems study

Description: The work was performed in three phases. The first phase included a review of the many possible laser-reactor-blanket combinations and resulted in the selection of a ''demonstration size'' 500 MWe plant for further study. A number of fast fission blankets using uranium metal, uranium-molybdenum alloy, and uranium carbide as fuel were investigated. The second phase included design of the reactor vessel and internals, heat transfer system, tritium processing system, and the balance of plant, exclu… more

SRL-NURE hydrogeochemical data management system

Description: A data management system was developed to store and retrieve all physical, chemical, and geological data collected for the NURE Hydrogeochemical Reconnaissance program by the Savannah River laboratory (SRL). In 1975, SRL accepted responsibility for hydrogeochemical reconnaissance of twenty-five states in the eastern United States as part of the National Uranium Resource Evaluation (NURE) program to identify areas favorable for uranium exploration. The SRL-NURE hydrogeochemical data management s… more

Temperature Distributions in Electron Beam Welding Cavities

Description: Surface temperatures in electron beam welding cavities in stainless steel 304 and aluminum 1100, 2024, and 6061 were measured with a narrow band infrared radiation pyrometer. A special device was designed for mounting the radiation-sensing probe next to the electron beam gun in the welding chamber. This mounting device included a mechanism for oscillating the probe so as to scan the cavity region both perpendicular and parallel to the welding direction. At the center of its movement the probe v… more

Progress report on modeling studies: Natural state conditions and exploitation of the Dachny geothermal reservoir, Mutnovsky hydrothermal system, Kamchatka, Russia

Description: The spatial distribution of pre-exploitation conditions (e.g. temperature and pressure distributions, liquid and vapor saturations, circulation characteristics of high-temperature fluids) in the Dachny site of the Mutnovsky hydrothermal system, obtained earlier using a 3-D mapping method (Kiryukhin et al, 1991), are revised on the basis of natural state simulations performed with the computer code TOUGH2 (Pruess, 1991). A 3-D model of the natural state conditions at the Dachny site was develope… more

Study of the atmospheric chemistry of radon progeny in laboratory and real indoor atmospheres

Description: This report covers the second year of the 28 month grant current grant to Clarkson University to study the chemical and physical behavior of the polonium 218 atom immediately following its formation by the alpha decay of radon. Because small changes in size for activity result in large changes in the delivered dose per unit exposure, this behavior must be understood if the exposure to radon progeny and it dose to the cells in the respiratory tract are to be fully assessed. Two areas of radon pr… more

Beta-energy averaging and beta spectra

Description: A simple yet highly accurate method for approximately calculating spectrum-averaged beta energies and beta spectra for radioactive nuclei is presented. This method should prove useful for users who wish to obtain accurate answers without complicated calculations of Fermi functions, complex gamma functions, and time-consuming numerical integrations as required by the more exact theoretical expressions. Therefore, this method should be a good time-saving alternative for investigators who need to … more

Laboratory experiment demonstrating the way in which a steam barrier prevents the dissolution of salt buried in a flooded packed bed. [Implications for preventing radionuclide migration near groundwater in underground explosions]

Description: We have conducted a laboratory experiment to demonstrate a way in which a solid material can be prevented from dissolving in water. The differential solubility of salt (NaCl) in steam vs water is exploited. As long as the temperature of the area and water surrounding the salt is maintained above the boiling point of water, the salt cannot dissolve. This phenomenon, known as the thermal barrier, has far-reaching implications for preventing the dispersal of contaminants present near groundwater s… more

A look at scalable dense linear algebra libraries

Description: We discuss the essential design features of a library of scalable software for performing dense linear algebra computations on distributed memory concurrent computers. The square block scattered decomposition is proposed as a flexible and general-purpose way of decomposing most, if not all, dense matrix problems. An object- oriented interface to the library permits more portable applications to be written, and is easy to learn and use, since details of the parallel implementation are hidden fro… more
