Analysis of binary vapor turbines

Description: The effect the binary mixture has on the turbine is examined in terms of design and cost. Several flow theories for turbines and turbine blading are reviewed. The similarity method, which uses dimensionless parameters, is used in determining rotative speeds and diameters for a variety of inlet temperatures and exit pressures. It is shown that the ratio of exit to inlet specific volume for each component in the mixture is the same for each specie. The specific volume ratio constraints are combin… more

Analysis of small-sample reactivity worths in the Fast Test Reactor Engineering Mockup Critical

Description: Small-sample reactivity worths were computed and compared with measurements at core center and along a radial traverse of the Fast Test Reactor Engineering Mockup Critical (FTR-EMC). The computed worths were obtained with first order perturbation theory using real and adjoint neutron fluxes from 42-group X-Y diffusion theory calculations. The perturbation denominator (importance-weighted neutron production rate) was obtained from three-dimensional X-Y-Z calculations. For most of the calculated … more

Annual report for FY 1976 on project AN0115A: the migration of plutonium and americium in the lithosphere

Description: Studies have been carried out on the migration of plutonium and americium in solutions flowing through porous and crushed rock and through fissures. The migration process can be described in terms of the surface absorption of these elements. In addition, chemical effects on the absorption have been observed. One of these effects is possibly due to the presence of a plutonium polymer that migrates at a more rapid rate than normal plutonium.

APPLICATION OF TURBOMACHINERY IN SOLAR-ASSISTED RANKINE COOLING SYSTEMS

Description: This report presents the results of a preliminary study concerning the use of high speed turbomachinery in a solar-assisted Rankine cooling cycle. The use of Rankine cycles in solar powered cooling of buildings involves a solar collector to provide energy to heat and vaporize a working fluid. Energy is extracted from this vapor in an expansion engine that is used to drive an air conditioning vapor compressor. In a typical Rankine cycle, the maximum temperature at the inlet to the expander is li… more

Biological conversion of biomass to methane. Quarterly progress report, September 1, 1976--November 30, 1976

Description: During the past quarter all experimental systems have become operational. The earlier problems with equipment acquisition have delayed the progress somewhat. However, most of these problems have been overcome such that the experimental programs have been initiated. This report will concentrate on the manure fermentation portion of this project. The study relating to the effect of reactor design is underway, but the results are too preliminary to evaluate. Therefore, no data from this activity w… more

Charged hadron and lepton currents produced by low-momentum (less than or equal to 3 GeV/c) charged pions in Al, Fe, and Pb targets. [0, 5 to 3 GeV/c, spatial dependence, tables, diagrams]

Description: Calculations were carried out to determine the spatial dependence of charged hadron and lepton currents produced by low momentum (less than or equal to 3 GeV/c) charged pions in Al, Fe, and Pb targets. Even at the lowest momentum values considered (0.5 GeV/c), there is little difference between incident positive pions and negative pions with respect to the average spatial dependence of the charged current.

Chemical equilibria relating the isotopic hydrogens at low temperatures

Description: Hydrogen fusion will require a fuel mixture of liquefied or frozen D/sub 2/ and T/sub 2/. The composition of this fuel mixture is described by the equilibrium constant K/sub DT/. The theory of isotopic exchange reactions is discussed as applied to the hydrogen isotopes. A literature survey of the values of K/sub HD/, K/sub HT/, and K/sub DT/ found no values of K/sub DT/ for temperatures below 25/sup 0/K and no values of K/sub HD/ and K/sub HT/ for temperatures below 50/sup 0/K.

Coal technology program. Progress report, October 1976

Description: In the hydrocarbonization/residue carbonization work, run HC-8 was completed with the 20-atm bench-scale hydrocarbonizer in a recirculating fluidized bed mode. Runs RC-15 and RC-16 in the 1-atm residue carbonizer showed very encouraging results--it appears that the system may be sufficiently operable for material balance experiments to begin. In engineering support of in-situ gasification, a two-dimensional pyrolysis gas production mechanism assumed to explain data obtained with as-received coa… more
