Materials evaluation for geothermal applications: turbine materials

Description: A number of candidate turbine materials are being evaluated for their resistance to erosion, corrosion, and stress corrosion cracking (SCC) in geothermal brines. These materials include Fe-, Ni-, Co and Ti-base alloys, coatings and ceramics. Tapered wearblades, simulating the leading edge of a turbine blade, are exposed to the direct impact of a two-phase nozzle exhaust. Bent beam SCC specimens, which are constrained in fixtures attached to the wearblade holders, are also exposed to this exhaus… more

Analysis of the response of geothermal reservoirs under injection and production procedures

Description: The response of a liquid-dominated geothermal reservoir to injection and production from a single well is studied. Different injection-production schemes are analyzed to explore how to minimize temporary cooling around the injection well and to optimize thermal recovery. The pressure response is also calculated, and found to be affected significantly by temperature-dependent viscosity variations. This will have implications on well-test methods for geothermal reservoirs. Vertical consolidation … more

Dry cooling for power plants: incentives, problems, and R and D activities

Description: Projecting the use of dry cooling at steam-electric plants within the next twenty years is fraught with more than the usual amount of uncertainty associated with long-range predictions. Eventually the industry's cooling requirements may exceed the availability of cooling water and require the direct rejection of heat to the atmosphere. However, projecting the physical availability of water and the growth of power generating capacity in various regions is not sufficient to determine the use of d… more

Important aspects of radiation shielding for fusion reactor tokamaks

Description: Radiation shielding is a key subsystem in tokamak reactors. Design of this shield must evolve from economic and technological trade-off studies that account for the strong interrelations among the various components of the reactor system. These trade-offs are examined for the bulk shield on the inner side of the torus and for the special shields of major penetrations. Results derived are applicable for a large class of tokamak-type reactors.

Vitrification of strontium-90 fluoride

Description: At Hanford, strontium-90 is removed from high-level nuclear fuel reprocessing waste and converted to strontium-90 fluoride. This /sup 90/SrF/sub 2/ is doubly encapsulated in high-integrity containers which are placed under water in monitored storage pools. Conversion of /sup 90/SrF/sub 2/ to a more immobile compound may be necessary and/or desirable as part of the overall plan for the long-term management of Hanford Defense Wastes. Glasses containing up to 40 mass percent SrF/sub 2/ and having … more

Solar proton fluxes since 1956

Description: The fluxes of protons emitted during solar flares since 1956 were evaluated. The depth-versus-activity profiles of /sup 56/Co in several lunar rocks are consistent with the solar-proton fluxes detected by experiments on several satellites. Only about 20% of the solar-proton-induced activities of /sup 22/Na and /sup 55/Fe in lunar rocks from early Apollo missions were produced by protons emitted from the sun during solar cycle 20 (1965--1975). The depth-versus-activity data for these radionuclid… more

How to estimate the solubility of an insoluble compound: 1,3,5-triamino-2,4,6-trinitrobenzene (TATB)

Description: A simple method for estimating the solubility of TATB in various solvents is presented. We consider it unlikely that a solvent will be found in which TATB is more soluble than 0.1 percent (w/v). Exceptions are the so-called superacids in which the solubility of TATB exceeds 20 percent (w/v).

EPMT: a portable transfer standard for telemetry system pressure-transducer calibration

Description: The LLL developed electronic pressure meter (EPMT) is a portable static-pressure calibration instrument for use with the LLL telemetry transducer system at the Nevada Test Site (NTS). It is significantly more accurate and rugged than the bourdon-tube pressure gauge it replaces, and can be incorporated into a field-use, semi-automatic, pressure calibration system. The process by which a transducer is selected for EPMT use from the inventory of field-service-certified transducers and subjected to… more

Very high-spin states in nuclei. [. gamma. spectra]

Description: The continuum ..gamma..-ray spectrum following neutron emission in a (HI,xn) reaction consists of a high-energy tail, the statistical cascade, and a lower-energy bump, the yrast cascade, which contains most of the intensity and consists mostly of stretched E2 transitions. Thus, a good approximation to the average angular momentum carried by the ..gamma..-rays is 2N/sub ..gamma../-bar. Under favourable conditions, effective moments of inertia can be deduced for states up to the top of the ..gamm… more

Mechanical design aspects of a tandem mirror fusion reactor

Description: Two ''plugs'' of dense plasma at either end of a central solenoid cell form the basis of a new mirror fusion power plant concept. A central cell blanket design is presented. Modules on crawler tracks serviced by remote welding and handling machines of very simple design are important features resulting from linear axisymmetric geometry. Three blanket designs are considered and the best one presented in some detail. It has lithium as the breeder material, helium cooled. ''Plug'' magnet field str… more

Anticipating the intermediate boson

Description: The cross sections for the production of W/sup +-/ and W/sup 0/ in the high energy pp and anti pp collisions and distributions of their decay products are calculated. The W productions are abundant (sigma/sub W/ approximately 10/sup -33/ cm/sup 2/) for s/m/sup 2//sub W/ greater than or equal to 10. The distributions of leptons from the W decay have pronounced peak structures. Sucn structures stand well above background and do not get smeared away by the transverse motion of the W, estimated fro… more

Computation of gas-liquid equilibria in high-saline geothermal fluids

Description: A computer-assisted chemical modeling study of equilibria in flowing brine systems has been undertaken. Equilibria between liquid and volatile components of two-phase fluids have profound effects on such important phenomena as corrosion, scale formation, environmental quality, and the economics of energy extraction. The principal reactions considered are those involving volatiles naturally present in the fluid, including NH/sub 3/, H/sub 2/S and CO/sub 2/. A computer code is described which per… more

Differential integral experiments for testing cross section evaluations for fusion reactors

Description: The conceptual design of fusion reactors and fusion-fission hybrid reactors brings into focus a large number of problems dealing with the interaction of 14-MeV neutrons with materials to be used in the design of the different components of the reactor. These components include the first wall, the blanket, the magnets and the shielding system. The accuracy of the design calculations can be assured, providing the transport codes correctly describe the interaction of 14-MeV neutrons with these mat… more

Geochemistry of Delaware Basin groundwaters

Description: Fluids from various formations were sampled and analyzed in order to characterize groundwaters in the Delaware Basin. Waters were analyzed for solute content and/or stable isotope ratios (D/H and /sup 18/O//sup 16/O). Three lines of geochemical arguments are summarized, in order to present the natures and probable origins of analyzed fluids: solute chemistry, thermodynamic modelling of low-temperature aqueous species, and stable isotope ratios.

High performance liquid chromatographic separations of retort water solutes were optimized using selected eluants on 25 cm bonded phase columns.

Review of neutron data: 10 to 40 MeV

Description: Neutron data are reviewed for incident neutron energies between 10 and 40 MeV. A census of the data shows that there are many gaps in this range and that the existing data are primarily for neutron energies around 14 MeV. Aside from total cross sections, there are few data between 10 and 13 MeV and between 15 and 40 MeV. Examples are presented to show the quality of selected data for total, elastic, inelastic, activation, and charged-particle and gamma-ray production cross sections. The spectra… more
