Multielement spark-gap switch system. Final report

Description: An engineering study was made to formulate a conceptual design for a multielement arc-type electrical switch system for switching 50,000-amp, 100-nsec or less pulses from a 50,000-v source at up to 1000 ppS. The switch is to have a lifetime of at least 5 x 10/sup 8/ pulse MTBF, litter time less than 10 nsec, closure time of less than 20 nsec, and 10 nh or less inductance. An offset midplane triggered spark gap (TSG) with ultraviolet (uv) preionization and forced air was selected as the most sui… more

Toxicity of tritium. [Chronic, low-dose exposure of mice and monkeys]

Description: Among radionuclides of importance in atomic energy, /sup 3/H has relatively low toxicity. The main health and environmental worry is the possibility that significant biological effects may follow from protracted exposure to low concentrations in water. To examine this possible hazard and measure toxicity at low tritium concentrations, chronic exposure studies were done on mice and monkeys. During vulnerable developmental periods animals were exposed to /sup 3/HOH, and mice were exposed also to … more

Concrete polymer materials as alternate materials of construction for geothermal applications - field test evaluations

Description: A serious problem in the development of geothermal energy is the availability of durable and economical materials of construction for handling hot brine and steam. Hot brine and other aerated geothermal fluids are highly corrosive and they attack most conventional materials of construction. Brookhaven National Laboratory has been investigating the use of concrete polymer materials as alternate materials of construction for geothermal processes. To date, successful field tests have been demonstr… more

Kelvin-Helmholtz-Like Instability of a Shear Layer Subject to Free Boundary Conditions

Description: For free boundary conditions a shear layer with linear velocity profile supports irrotational disturbances, one mode being unstable when its wavelength lambda > 2.619 times the thickness h of the shear layer. For long wavelengths the dispersion relation of the mode approaches Kelvin-Helmholtz form.

Lawrence Livermore Laboratory Geothermal Energy Program. A Status Report on the Development of the Total-Flow Concept

Description: The technology development activities of the Geothermal Energy Program at the Lawrence Livermore Laboratory are summarized. Significant progress toward development of the Total-Flow concept was made during FY 1978. The results show that the original goal of 70% engine efficiency for the Total-Flow impulse turbine is achievable, that a Total-Flow system is competitive economically with conventional systems, and that the Total-Flow concept offers the benefit of more efficient utilization of geoth… more

Removal of plutonium from high-level caustic waste solutions using bone char: pilot study

Description: Pilot studies have been completed using 275-..mu..m bone char as an adsorbent for the removal of plutonium, in concentrations ranging up to 8 mg/liter, from caustic waste solutions. These waste solutions were adjusted to an approximate pH of 8 before they were passed through columns of the bone char. Overall decontamination factors of about 5 x 10/sup 9/ were obtained. A tentative design of a caustic waste treatment system utilizing cartridge filters and bone char columns was made. Its advantag… more

Determination of continuous gamma-ray spectra over the energy range 0. 1 to 8 MeV. [RETECTUR code]

Description: An experimental facility was established at LLL to characterize radiation fields produced by a variety of sources and transmitted through various shielding materials. Specific techniques for acquiring and reducing continuous gamma-ray energy spectra are discussed including NaI(Tl) detectors. Use of several detector sizes allowed study of a wide variety of source intensities and calculation of response matrices for a number of collimated detector configurations. A computer program to perform the… more

Mortality, migration, income, and air pollution: a comparative study

Description: The interrelationships among different demographic factors, specific causes of death, median family income, and estimated air pollution emissions were examined. Using the Medical Data Base (MEDABA) developed at Brookhaven National Laboratory, the entire population of the United States was cross-tabulated by income and emission levels of air pollutants. Path analysis was used to examine a number of patterns and relationships for each age, race, and sex group containing a minimum of 10,000 person… more

Assessment of fire hazards in buildings housing fusion energy experiments

Description: A number of materials in and within the proximity of buildings housing fusion energy experiments (FEE) were analyzed for their potential fire hazard. The materials used in this study were mostly: electrical and thermal insulations. The fire hazard of these materials was assessed in terms of their ease of ignition, heat release rate, generation of smoke, and the effect of thermal environment on the combustion behavior. Several fire protection measures for buildings housing the (FEE) projects are… more

Fluid loads on LOFT DTT shrouds located in reactor vessel downcomer and DTT thermal loads during nuclear LOCE

Description: A thermal analysis was performed on a LOFT drag disc turbine (DTT) for a nuclear LOCE. Thermal gradients through the DTT shroud and turbine body, and temperature differences between body and shroud were calculated. This was done to determine the possible need for additional stress analyses of the DTT shroud to body welds based on thermal loads for a nuclear LOCE.

Fracture mechanics evaluation of some LOFT blowdown system and primary coolant coldleg welds

Description: Fracture mechanics evaluations were performed for three welds in the LOFT blowdown system and one weld in the LOFT primary coolant system. Because the applied stress is not known, a sensitivity analysis was run. The assumed initial defect size was one that had a small probability of being missed; applied stresses of 68.9, 137.8, 206.7, and 344.8 MPa were used. It was found that at the lowest stress (68.9 MPa or 10 ksi) the number of cycles from the initial size to rupture was over 6 x 10/sup 6/… more
