The principal objectives of the NCSL Geothermal Project was to stimulate and assist state legislative action to encourage the efficient development of geothermal resources, including the use of groundwater heat pumps. The project had the following work tasks: (1) initiate state geothermal policy reviews; (2) provide technical assistance to state geothermal policy reviews; (3) serve as liaison with geothermal community; and (4) perform project evaluation.

As a means of investigating unified gauge theories of the electro-weak interaction we have been preparing an experiment for the Bates Electron Accelerator to determine the parity violating asymmetry A = (sigma/sub R/ - sigma/sub L/) for 30/sup 0/ elastic scattering by /sup 12/C of 250 MeV longitudinally polarized electrons, where sigma/sub R/ and sigma/sub L/ are respectively the differential cross sections for electrons with right and left helicities. The asymmetry depends strictly on the isoscalar vector-hadronic coupling constant, and in terms of the Weinberg-Salam model is predicted to have a value of approx. 2 x 10/sup -6/ for our choice of kinematics. Central to the success of the measurement of such a small quantity is the use of an intense, highly stable source of polarized electrons. The progress in the development of such a source, based upon photoemission from GaAs, is reviewed in this report.

Using a fairly typical mobile home design, it is shown that state-of-the-art mobile/modular housing and passive solar techniques can be used together. Computer simulations are used to analyze the concept. Size conditions at a mobile home park are considered. Glazing orientation, shading, and thermal storage are included in the analysis. (LEW)

Uranyl nitrate solution from 200-Area processing of spent SRP fuel tubes is now sent to Oak Ridge Y-12 for conversion of uranium metal. However, after implementation of the powder metallurgy (P/M) process, U{sub 3}O{sub 8} powder will be needed at SRP but not uranium metal. U{sub 3}O{sub 8} powder for fabrication and irradiation tests was produced during development of P/M at SRL by firing UO{sub 3}, obtained from Y-12, at 800{degrees}C for 6 hours in a low grade nitrogen atmosphere. The UO{sub 3} powder was produced by denitration of unsulfated uranyl nitrate solution. The stoichiometry, particle size distribution, surface area and density of the Y-12 and SRL powders were measured. A comparison was then made between SRL U{sub 3}O{sub 8} produced at 800{degrees}C in nitrogen and in air and U{sub 3}O{sub 8} produced at Y-12 at other heating temperatures.

This report provides background and discusses the inventory and disposal of public lands and other Federal property. For many years the Federal Government has operated under a statutory policy of retaining public domain lands and has disposed of the proceeds from the sale of surplus property other than by the reduction of the national debt. Under the present system, the Government disposes of some types of land when it is determined to be surplus to Government needs, or, in the case of public lands, when it is determined that the national interest would best be served by the sale or exchange of particular tracts of land.

In September 1982 the Hazards Control Department of the Lawrence Livermore National Laboratory (LLNL) began a final radiological survey of a former low-level radioactive waste storage area called the Taxi Strip so that the area could be released for construction of an office building. Collection of soil samples at the location of a proposed sewer line led to the discovery of an old disposal pit containing soil contaminated with low-level radioactive waste and organic solvents. The Taxi Strip area was excavated leading to the discovery of three additional small pits. The clean-up of Pit No. 1 is considered to be complete for radioactive contamination. The results from the chlorinated solvent analysis of the borehole samples and the limited number of samples analyzed by gas chromatography/mass spectrometry indicate that solvent clean-up at this pit is complete. This is being verified by gas chromatography/mass spectrometry analysis of a few additional soil samples from the bottom sides and ends of the pit. As a precaution, samples are also being analyzed for metals to determine if further excavation is necessary. Clean-up of Pits No. 2 and No. 3 is considered to be complete for radioactive and solvent contamination. Results of analysis for metals will …

Since the issuance of UCRL 50400 Vol. 23, ENSL and CDRL: Evaluated Nuclear Structure Libraries, errors have been noted in half-lives. Most of these errors were for half-lives represented in exponential form, where the exponent is positive. This situation occurs only when the unit for half-life is years. A few errors were associated with ground states having unknown half-lives. These were incorrectly labeled as stable (i.e., a value of 1.0 E + 50 s was entered). Such ground states are assigned half-lives of 1.0 E - 20 s in the new version of the two data files. In all, we found a total of 65 levels that had incorrect half-lives. These levels and the corrected half-lives are listed.

The Old-Age and Survivors Insurance (OASI) program, the largest of the social security programs, will not have sufficient resources to meet its benefit payments on time in July 1983. Even if the program were permitted to continue to borrow from the other social security programs, the financial the shortfall would re-emerge in 1984.

Research supported by OHER and its predecessors has as one of its major goals an understanding of the effects of radiation at low doses and dose rates on biological systems, so as to predict their effects on humans. It is not possible to measure such effects directly. They must be predicted from basic knowledge on how radiation affects cellular components such as DNA and membranes and how cells react to such changes. What is the probability of radiation producing human mutations and what are the probabilities of radiation producing cancer? The end results of such studies are radiation exposure standards for workers and for the general population. An extension of these goals is setting standards for exposure to chemicals involved in various energy technologies. This latter problem is much more difficult because chemical dosimetry is is a primitive state compared to radiation dosimetry.

Magnetic field and flux distribution for the CDF detector is calculated using a TRIM program. The flux distribution in the system is calculated at several different excitation levels with an expected B-H curve.

The Natural Gas Policy Act of 1978 (NGPA) culminated decades of dispute over natural gas policy and was the "centerpiece of President Carter's National Energy Act. Now there are many issues of both regulatory and legislative concerns under discussion. These items were unanticipated by the framers of this difficult and delicate compromise. Generally speaking, they all stem from the fact that oil prices more than doubled in 1979 and 1980. The NGPA1s framers set wellhead gas prices within the new law's framework in such a way that they would converge on oil equivalent prices -- as they were then perceived -- in real dollar terms by 1985.

One Energy Saver Dipole Beam Tube (No. MB 124211) was tested under static and pulsed pressure conditions. Under static pressure, permanent deformation started at about 125 psi and reached .006 inches across flats after 220 psi exposure. Final catastrophic collapse occurred at 325 psi. Pressure pulses of shape and duration approximating the single phase helium pressure during a full house quench had no effect on the tube (previously staticly pressurized to 220 psi) up to 285 psi and a slight yield effect at 305 psi. Repeated pulses at 305 psi appeared to cause little or no further yielding. When compared to static pressure effects the 305 psi pulse produced the same deflection as about 235 psi static pressure.

Efforts were concentrated on the development of H/sup -//D/sup -/ sources capable of delivering about 1A of beam current, operating steady state at an energy of several tens of keV and having properties that would allow a scaling up to 10A and their use in a high energy neutral beam line. In the seventies we have developed negative ion sources of the plasms surface type with extracted current densities of several hundred mA/cm/sup 2/. Particularly successful was the development of the magnetron source, from which pulsed beam currents in excess of one ampere have been obtained and accelerated up to 120 kV. These magnetrons have become standard sources in high energy accelerator laboratories around the world and they are candidates for application in polarized H/sup -/ ion sources as well. Work on hollow cathode deuterium sources and neutraizers is reported.

Commonly, abatement of hydrogen sulfide emission from a geothermal powerplant requires that hydrogen sulfide dissolved in the cooling water be eliminated by chemical reaction. Oxidation by atmospheric oxygen is the preferred reaction, but requires a suitable catalyst. Nickel is the most potent and thereby cheapest catalyst for this purpose. One mg/L nickel in the cooling water would allow 99% removal of hydrogen sulfide to be attained. A major drawback of catalytic air oxidation is that colloidal sulfur is a major reaction product; this causes rapid sludge accumulation and deposition of sulfur scale. We studied the kinetics and product distribution of the reaction of hydrogen sulfide with oxygen, catalyzed by nickel. Adding sodium sulfite to the solution completely suppresses formation of colloidal sulfur by converting it to thiosulfate. The oxidation reaction is an autocatalytic, free radical chain reaction. A rate expression for this reaction and a detailed reaction mechanism were developed. Nickel catalyzes the chain initiation step, and polysulfidoradical ions propagate the chains. Several complexes of iron and cobalt were also studied. Iron citrate and iron N-hydroxyEDTA are the most effective iron based catalysts. Uncomplexed cobalt is as effective as nickel, but forms a precipitate of cobalt oxysulfide and is too …

We describe the models used to calculate the equilibrium operating point for the MARS mode of the axicell MFTF-B, and present the model equations necessary to calculate the plasma and potential parameters in the central-cell, axicell, and anchor regions. In addition, we calculate the neutral beam, rf power, and gas inputs required to sustain the plasma and maintain the ion and electron-particle energy balance. After a brief description of the MFTF code, we present the results of a sample calculation using MFTF.

Ultimate strength and shear wave velocity of dry, 50% saturated, and saturated Paintbrush tuff samples from the Nevada Test Site (NTS) are measured as a function of pressure up to 400 MPa. A linear relationship exists between the ultimate strength (tau) and shear modulus (..mu..) for the dry tuff at pressures from 0.1 to 20 MPa and from 100 to 300 MPa, with values of d tau/d..mu..; of about 1.25 x 10/sup -2/ and 2.6 x 10/sup -2/, respectively. At pressures between 20 and 100 MPa a linear relationship also exists with a much greater value of d tau/d..mu.., of about 9.9 x 10/sup -2/. For the half-saturated tuff, under undrained testing conditions, a similar linear relationship exists at pressures up to 20 MPa. At pressures between 20 and 300 MPa the data of the partially saturated tuff have too much scattering to deduce a meaningful relation. No such correlation can be found for the saturated tuff sample under undrained testing conditions. If similar relations could be found for other rock types and under other controlled experimental coditions, such as at a fixed pore fluid pressure (drained test) or temperature, then the results would be very valuable for the estimation …
