1976 intercomparison of personnel dosimeters

Description: The second Personnel Dosimeter Intercomparison Study (PDIS) was conducted at Oak Ridge National Laboratory's DOSAR Facility during the period February 18-19, 1976. Eleven independent organizations participated in an intercomparison of neutron and gamma-ray dosimeters used for routine personnel dosimetry. The dosimeters, which were shipped to the DOSAR Facility, were exposed at the Health Physics Research Reactor to one of three ''standardized'' radiation fields which have been used for the past… more

Analyses of grain boundary reactions in aluminum--zinc alloys utilizing lattice imaging electron microscopy

Description: Lattice imaging and conventional transmission electron microscopy have been applied in an investigation of the relationship between grain boundary structure and boundary-nucleated phase transformations. The study encompassed three reactions associated with grain boundaries in the Al-Zn system: heterogeneous nucleation at grain boundaries, discontinuous precipitation involving the R-phase and the low temperature discontinuous reaction. In conjunction with image computations, lattice images were … more

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

Analysis of Well Tests with Variable Discharge

Description: The conventional methods of well tests analysis usually assume a constant rate of discharge of the producing well. The procedure involves matching a log-log plot of test data (drawdown versus time) to analytic or semi-analytic solutions that are based on a model of the production well as a line source of constant strength in an infinite reservoir. However, variable discharge well test conditions may arise under a variety of conditions, such as existing well-field production schedules, step-draw… 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 Thermal Depletion Model to Geothermal Reservoirs with Fracture and Pore Permeability

Description: The useful lifetime of a geothermal resource is usually calculated by assuming fluid will be produced from and reinjected into a uniform porous medium. However, most geothermal systems are found in fractured rock. If the reinjection and production wells intersect connected fractures, then reinjected fluid may cool the production wells much sooner than would be predicted from calculations of flow in a porous medium. We have developed a “quick and dirty” method for calculating how much sooner tha… more

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

Benefit analysis of reprocessing and recycling light water reactor fuel

Description: The macro-economic impact of reprocessing and recycling fuel for nuclear power reactors is examined, and the impact of reprocessing on the conservation of natural uranium resources is assessed. The LWR fuel recycle is compared with a throwaway cycle, and it is concluded that fuel recycle is favorable on the basis of economics, as well as being highly desirable from the standpoint of utilization of uranium resources.

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

Borehole Geophysics in Geothermal Wells--Problems and Progress

Description: Surface geophysical techniques are readily adaptable to exploration for and evaluation of geothermal reservoirs because existing equipment and interpretive models can be used. In contrast, the application of borehole geophysics for these same purposes requires the development of equipment to operate dependably in the very hostile environment of some geothermal wells. After equipment ahs been developed and tested, its response must be calibrated with respect to required parameters such as lithol… more

Buoyancy Induced Boundary Layer Flows in Geothermal Reservoirs

Description: Most of the theoretical study on heat and mass transfer in geothermal reservoirs has been based on numerical method. Recently at the 1975 NSF Workshop on Geothermal Reservoir Engineering, Cheng presented a number of analytical solutions based on boundary layer approximations which are valid for porous media at high Rayleigh numbers. according to various estimates the Rayleigh number for the Wairakei geothermal field in New Zealand is in the range of 1000-5000, which is typical for a viable geot… more

A Calculation Model for the P-V-T-X Properties of Geothermal Brines

Description: A set of P-V-T-X data for the highly saline fluids encountered in some geothermal reservoirs is an important prerequisite to the modeling of the chemical and physical behavior of geothermal reservoirs. However, very limited data at the temperatures and pressures encountered in the geothermal systems are available (Potter, 1976). In this paper, we present relatively simple workable models which can be used to predict accurately both the density and vapor pressure of complex brines at elevated te… more
