Management of waste cladding hulls. Part II. An assessment of zirconium pyrophoricity and recommendations for handling waste hulls

Description: This report reviews experience and research related to the pyrophoricity of zirconium and zirconium alloys. The results of recent investigations of the behavior of Zircaloy and some observations of industrial handling and treatment of Zircaloy tubing and scrap are also discussed. A model for the management of waste Zircaloy cladding hulls from light water reactor fuel reprocessing is offered, based on an evaluation of the reviewed information. It is concluded that waste Zircaloy cladding hulls … more

Assessment of a small pressurized water reactor for industrial energy

Description: An evaluation of several recent ERDA/ORNL sponsored studies on the application of a small, 365 MW(t) pressurized water reactor for industrial energy is presented. Preliminary studies have investigated technical and reliability requirements; costs for nuclear and fossil based steam were compared, including consideration of economic inflation and financing methods. For base-load industrial steam production, small reactors appear economically attractive relative to coal fired boilers that use coal… more

Solar heating and cooling of buildings: Phase I (non-residential). InterTechnology/Solar Corporation cost/benefit analysis report and supporting opinion survey, commercial buildings. National Solar Demonstration Program, executive summary

Description: A parametric study was performed to provide an estimate of the number of non-residential solar demonstration projects that will be required to start a commercial industry in solar equipment manufacturing, marketing, financing, and installation. An opinion survey was conducted among several experts in the field and results are shown. A techno-economic computer simulation of the solar industry was constructed. This simulation predicts the response of the marketplace to the ERDA program. The compu… more

Biological conversion of organic refuse to methane. Final report, July 1, 1973--November 30, 1976

Description: In order to predict accurately the cost of producing methane from urban refuse, studies were initiated on the dewatering of the fermentor residue and the disposal of the residue from the system. Results of the research are reported under the following subject headings: fermentation system; rheological properties of reactor slurry; filterability of reactor effluent; residue dewatering--vacuum filtration; settleability of solids in the reactor effluent; settleability of sludges from centrate trea… more

Does oxygen enhance the radiation-induced inactivation of penicillinase. Progress report, December 1, 1979-November 30, 1980

Description: The radiation-induced inactivation of penicillinase in dilute aqueous solutions buffered with phosphate was studied, by examining enzyme radiosensitivity in the presence of various gases (He, O/sub 2/, H/sub 2/, N/sub 2/O, N/sub 2/O + O/sub 2/). The introduction of either N/sub 2/O or O/sub 2/ was found to reduce the radiodamage. On the other hand H/sub 2/ or N/sub 2/O + O/sub 2/ gas-mixture enhanced the radiosensitivity. In the presence of formate and oxygen, no enzyme inactivation was detecte… more

Measurement of pressure, fluidized bed level, and density in the Synthane Pilot Plant coal gasifier

Description: Fluid bed densities and levels are usually obtained from measurement of differential pressures between taps with a known vertical separation. Historically, this measurement has been difficult in high pressure coal gasification processes primarily due to plugging of the pressure taps and process instrument tubing. Likewise, the achievement of accurate and reliable pressure and differential pressure recordings is affected by similar circumstances. These typical problems were experienced at the SY… more

Accurate machining

Description: Very minor test part experience of the all-rotary machine has been obtained. Results at this point appear to verify that the machines (both in the three axis and in the phonograph configuration) are inherently more accurate than machines with slides. Much more work is needed to define the desirable operating parameters and the size capacity of the all rotary machine. A second generation three axis machine is in the design stage which abandons mounting the vertical axes from the top, and instead… more

Mechanics of micromachining

Description: The current state of machining theory is examined for relevance to micromachining. Of particular interest are those features of the theory which are important to optical surface finishes and surface characteristics. The relation of transverse strain or side flow to the nature of the machining marks is one example of interest. Correlation with measurements of machining parameters and surface finishes is given.

Characterization and Research Investigation of Methanol and Methyl Fuels. Final Progress Report

Description: Work on several aspects of using pure methanol as an alternate fuel are reported. A stock (OEM) Pinto engine mounted on a dynamometer was used to compare methanol with Indolene in terms of power, efficiency, and emissions for a variety of speeds and loads. Although the engine was designed for use with gasoline, it was found that methanol was generally superior in power, thermal efficiency and reduced emissions with the exception of aldehydes. Three different fuel metering systems were tested fo… more

Gasification in pulverized coal flames. First quarterly progress report, July--September 1975

Description: This project is concerned with the production of power and synthesis gases from pulverized coal via suspension gasification. Specifically, the concentric jet and vortex gasifiers, with separation of oxidation and reduction zones, will be investigated. Gasifier performance will be correlated with internally measured temperature and concentration profiles. A suction pyrometer will be used to simultaneously measure temperature and gas concentrations. Rapid species analysis will be provided by a UT… more
