The radial-outflow reaction turbine, a pure-reaction turbine designed to improve the conversion efficiency of geothermal energy into electrical power is described. It also has potential as a total-flow turbine for low-temperature water. The principle of incomplete expansion can be used to obtain a reduction in turbine size when the turbine exhausts into a low-pressure condenser. And, by adding this turbine to single- and two-stage flashed-steam systems, the conversion efficiency of systems utilizing low- and high-energy wellhead sources, respectively can be improved. The Appendix outlines the analysis of the radial-outflow reaction turbine and leads to an expression for engine efficiency.

This volume consists of four topical reports: a general discussion of the philosophy of unfolding spectra with continuum and discrete components, a mathematical treatment of the effects of various physical parameters on the uncollided gamma-ray spectrum at aircraft elevations, a discussion of the application of the unfolding code MAZNAI to airborne data, and a discussion of the effects of the nonlinear relationship between energy deposited and pulse height in NaI(T1) detectors.

Recognizing the need to consider several potentially suitable sites for disposal of high-level radioactive wastes, a very preliminary search was made through available data for such sites in the North Pacific and West North Atlantic Oceans. The criteria used were: the site must be between high-productivity belts and outside of 200 mile limit; a minimum of 50 meters of sediment, preferably 100 to 150 meters; the sediment should be red clay with minimum or no biogenic components; the sediment should contain no unconformities; and no strong discontinuous internal reflectors; the area should have no tele-seismicity, be topographically subdued, have minimal bottom currents, have no or low economical potential (Mn nodules, etc.), and be large enough (1 to 2/sup 0/ on a side) to be feasible for disposal. Some of these criteria may need to be relaxed; others may need to be added. Seismic data were the basic information used to cull out potential areas, and there are very few areas that meet the criteria as interpreted seismically. Initial site specific data assessment reported included examination of all available geophysical/geological data in and around the MPG-1 area (approximately 29/sup 0/ to 31/sup 0/N; approximately 156/sup 0/ to 160/sup 0/W); a topographic …

The calculation of burnup in mixed-oxide fuel pins irradiated in EBR-II is shown to agree with burnup measured by postirradiation radiochemical analysis. The mean percent deviation is 0.12% with a variance of 2.49%. This gives a high level of confidence that HIST, which uses 91% of the nominal EBR-II power, provides an accurate estimate of burnup.

The problems associated with reinjecting spent geothermal brines are currently under investigation. This effort has included field tests of injection water to evaluate treating equipment effectiveness at the Niland Geothermal Test Loop. Membrane filter tests were conducted on fluids from the settling tanks, from the test loop, from the clarifier and at the injection well head (Magmamax No. 3). From this and other information concerning the injection interval, pressure, temperature and well history, an attempt to predict a well half life was made. The results of these calculations were not in agreement with observed well performance. An attempt with some apparent success has been made to understand the possible source of these discrepancies. The cyclic nature of the injection history dictated by need for descaling the test loop, followed by apparent partial recovery of injection acceptance, has led to a theory that is under investigation concerning effect of reheating the injection fluid containing amorphous particulate silica by the reservoir rock and fluid during well shut-in. Preliminary tests indicate some of this finely divided silica may be redisolving with consequent reduction in reservoir damage, and that two widely spaced injection wells in an alternating mode may provide low-cost, long-life injection capacity …

Environmental monitoring results continue to demonstrate that, except for penetrating radiation, environmental radiological impact due to SLAC operation is not distinguishable from natural environmantal sources. During 1977, the maximum neutron dose near the site boundary was 8.2 mrem. This represents about 8.2% of the annual dose from natural sources at this elevation, and 1.6% of the technical standard of 500 mrem per person annually.

Report of the test results of a pulsed eddy-current apparatus for inspecting the integrity of smooth and ribbed tubing as well as discussion of transducer and preamplifier features, scanning procedures, and theory of operation.

The use of outside diameter ribs on nuclear reactor tubing presents severe problems to nondestructive testing of this tubing. A pulsed eddy-current apparatus for inspecting the integrity of smooth and ribbed tubing has been developed at Argonne National Laboratory. Test results for this apparatus and analysis and circuit block diagrams are presented. In addition, transducer and preamplifier features, scanning procedures, and theory of operation are discussed. To date, this apparatus has provided the best solution to the ribbed tubing problem because of its capability to time-sample data.

This report is the final report on the field investigations in Eaton's Neck Disposal Site, Long Island Sound.

The AREAS area-source computer code, written in FORTRAN IV, is described and listed. This code, which runs in less than 7 seconds on the IBM 360/91 computer, estimates annual-average concentrations of an air pollutant at ground level in each of 400 grid squares in a 20 by 20 area reference grid. AREAS can be used for multiple, dispersed sources located in each of the 400 grid squares by treating them as area sources. Required input includes 20 by 20 arrays of annual-average point-source chi/Q values generated by use of a point-source model or computer code for specific grid sizes relative to the size of the area reference grid. AREAS can be applied to any size area for which a uniform meteorology can be assumed. It has been applied to dispersed emissions of fossil fuel combustion products and automobile emissions in Roane County, Tennessee, and to the atmospheric dispersion of radionuclides emitted from the tailings piles of uranium mills.

Surface topography of texturized solar cells was investigated., No significant differences were found between high output and low output cells with a common texturizing treatment. Differences were found between high output and low output cells with a common texturizing treatment. Differences were found associated with variation in the damage removal etch prior to texturizing.

This report summarizes the expected tritium and activation-product inventories and presents an assessment of the potential radiological releases from a fusion reactor power plant, hypothetically located at the Oak Ridge National Laboratory. Routine tritium releases and the resulting dose assessment are discussed. Uncertainties associated with the conversion of tritium gas to tritium oxide and the global tritium cycling are evaluated. The difficulties of estimating releases of activated materials and the subsequent dose commitment are reviewed.

The atomic iodine photodissociation laser has been under intensive study for a number of years. The physics associated with this system is now well understood and it is possible to produce a 0.1 nsec (or longer) near-diffraction-limited laser pulse which can be amplified with negligible temporal distortion and little spatial deformation. The output of either a saturated or unsaturated amplifier consists of a high-fidelity near-diffraction-limited, energetic laser pulse. The report is divided into three chapters. Chapter 1 is a survey of the important areas affecting efficient laser operation and summarizes the findings of Chap. 2. Chapter 2 presents detailed discussions and evaluations pertinent to pumps, chemical regeneration, and other elements in the overall laser system. Chapter 3 briefly discusses those areas that require further work and the nature of the work required to complete the full-scale evaluation of the applicability of the iodine photodissociation laser to the inertial confinement program.
