Analysis of Mirnov oscillations on PDX
Mirnov coils have been used to study MHD oscillations in PDX. We first review the information that can be obtained from Mirnov coils concerning the amplitude of these oscillations and their toroidal and poloidal mode numbers. The usual techniques for analyzing Mirnov coil data do not work well on PDX because of the rectangular arrangement of the coils, substantial noise levels, and poloidal amplitude asymmetries. A technique using digital Fourier analysis to focus attention on the fundamental frequency component of the signals has been successful in determining the m and n model numbers of Mirnov oscillations in the PDX tokamak.

Application of US upper wind data in one design of tethered wind energy systems
The upper atmospheric wind resource for the continental United States, Hawaii, and Alaska is assessed. The raw data were obtained from the National Center for Atmospheric Research, Boulder, Colo. The probability distributions of velocity are presented for 54 sites, and detailed calm wind analyses have been undertaken for five of these locations. On the average, the wind lulls about one day per week for a period in excess of about 30 hours. It is shown that the average power density of this wind resource can be as high as 16 kW/m/sup 2/ at northeastern US sites. This power density is at a maximum around the 300-mb pressure level.

Simplified scaling model for the THETA-pinch
A simple ID scaling model for the fast THETA-pinch was developed and written as a code that would be flexible, inexpensive in computer time, and readily available for use with the Los Alamos explosive-driven high-magnetic-field program. The simplified model uses three successive separate stages: (1) a snowplow-like radial implosion, (2) an idealized resistive annihilation of reverse bias field, and (3) an adiabatic compression stage of a BETA = 1 plasma for which ideal pressure balance is assumed to hold. The code uses one adjustable fitting constant whose value was first determined by comparison with results from the Los Alamos Scylla III, Scyllacita, and Scylla IA THETA-pinches.

Geothermal-well design handbook
A simplified process is presented for estimating the performance of geothermal wells which are produced by natural, flashing flows. The well diameter and depth, and reservoir conditions must be known; then it is possible to determine the total pressure drop in a flowing well, and therefore to find the fluid pressure, temperature, and steam quality at the wellhead. By applying the handbook process to several input data sets, the user can compile sufficient information to determine the interdependence of input and output parameters. (MHR)

Hazardous-waste analysis plan for LLNL operations
The Lawrence Livermore National Laboratory is involved in many facets of research ranging from nuclear weapons research to advanced Biomedical studies. Approximately 80% of all programs at LLNL generate hazardous waste in one form or another. Aside from producing waste from industrial type operations (oils, solvents, bottom sludges, etc.) many unique and toxic wastes are generated such as phosgene, dioxin (TCDD), radioactive wastes and high explosives. One key to any successful waste management program must address the following: proper identification of the waste, safe handling procedures and proper storage containers and areas. This section of the Waste Management Plan will address methodologies used for the Analysis of Hazardous Waste. In addition to the wastes defined in 40 CFR 261, LLNL and Site 300 also generate radioactive waste not specifically covered by RCRA. However, for completeness, the Waste Analysis Plan will address all hazardous waste.

Effect of organic complexants on the mobility of low-level-waste radionuclides in soils
The effect of certain organic complexants on the distribution of some radionuclides between solution and soil has been measured. The complexants and radionuclides examined are some of those most likely to be present in low-level waste disposal sites; Cs, Sr, Ni, Co, and Eu radionuclides, and EDTA, DTPA, oxalate, and citrate complexants. The effect of complexants was found to vary widely; in some systems there was no effect and in other systems there were large effects. In some cases slow rates of reaction have not allowed equilibrium measurements to be made.

Proposal to develop techniques using magneto-optic and electro-optic effects in optical fiber for CTR diagnostics
We discuss the developing technology of measuring electric and magnetic fields with optical fibers using the Faraday and Kerr effects, magnetostriction, and Sagnac interferometry. We review the measurement of induced birefringence in the presence of natural birefringence. We propose the use of these effects in making measurements in the fusion research program, with ZT-40 as an example.

Hunt for the 1/sup 1/P/sub 1/ bound state of charmonium
Using the Crystal Ball detector at SPEAR, we have looked for evidence of the isospin-violating decay psi' ..-->.. ..pi../sup 01/P/sub 1/, where /sup 1/P/sub 1/ is the predicted spin-singlet p-wave bound state of charmonium. For a /sup 1/P/sub 1/ state at the predicted mass (approx. 3520 MeV), we obtain the 95% confidence level limits: BR(psi' ..-->.. ..pi../sup 01/P/sub 1/) < 0.55%, BR(psi' ..-->.. ..pi../sup 01/P/sub 1/)BR(/sup 1/P/sub 1/ ..-->.. ..gamma..n/sub c/ < 0.14%. These limits are compared with simple theoretical predictions.

Health and safety evaluation of a modified tunnel-borer design for application to single-entry coal-mine development
The health and safety analysis is part of an overall effort to identify and develop innovative underground coal extraction systems. The single-entry tunnel borer system was initially considered an innovative approach to underground mining because it exhibited a means of increasing the speed and efficiency of entry development by reducing the number of entries. However, to be considered a truly advanced system, the tunnel borer had to meet distinct safety criteria as well. The objective was to examine the tunnel borer design and determine whether it offset major health hazards, and satisfied the prescribed safety levels. As a baseline for comparison, the tunnel borer was compared against the continuous mining entry driving system. The results of the health analysis indicated that while the tunnel borer design offered improvements in dust control through the use of water sprays, a higher face ventilation rate, and the application of spalling rather than the conventional grinding process, it interjected an additional mutagenic is and toxic compound into the environment through the use of shotcrete. The tunnel borer system easily conformed with the prescribed fatality limit, but exceeded the required limits for disabling and overall injuries. It also exhibited projected disabling and overall injury rates …

The effect of expansion-ratio limitations on positive-displacement, total-flow geothermal power systems
Combined steam-turbine/positive-displacement engine (PDE) geothermal power systems are analyzed thermodynamically and compared with optimized reference flash-steam plants. Three different configurations of combined systems are considered. Treated separately are the cases of self-flowing and pumped wells. Two strategies are investigated that help overcome the inherent expansion-ratio limitation of PDE's: pre-flashing and pre-mixing. Parametrically-obtained results show the required minimum PDE efficiency for the combined system to match the reference plant for various sets of design conditions.

Lithologic interpretation of the De Braga No. 2 and Richard Weishaupt No. 1 geothermal wells, Stillwater project, Churchill County, Nevada
Lithologies penetrated throughout the upper 732 to 838 m (2400 to 2750 ft) within the Stillwater prospect area are terrigenous sediments of Pleistocene to Recent age. A sill of dacite to andesite composition with a thickness variable between 122 to 208 m (400 to 680 ft) is present below the terrigenous sediments. Between the base of the sill and the top of the Bunejug Formation are intercalated volcanic and sedimentary rocks. All formations overlying the Bunejug Formation are probably of Pleistocene age. The basalt and basaltic-andesite flows and ash below the depth of approximately 1128 m (3700 ft) are herein assigned to the Bunejug Formation (Morrison, 1964) of Pliocene and possibly early Pleistocene age. The Bunejug Formation is a thick sequence of basalt to andesite flows and hyaloclastite exposed in the mountains surrounding the south half of the Carson Desert. The De Braga No. 2 well bottomed in Bunejug volcanics at a depth of 2109 m (6920 ft). The Richard Weishaupt No. 1 well penetrated the entire Bunejug sequence and entered felsic volcanics and tuffaceous sediments, which possibly represent part of the Truckee Formation, at a depth of approximately 2412 m (7915 ft).

Accurate monotonicity-preserving cubic interpolation
A simple and effective algorithm to construct a monotonicity-preserving cubic Hermite interpolant for data with rapid variations is presented. Constraining the derivatives of the interpolant according to geometric considerations makes the interpolant consistent with local monotonicity properties of the data. Numerical examples are given that compare the quality and accuracy of the proposed interpolation method with other standard interpolants.

LAPA: a composite indicator for prioritization of geothermal-leasing activities on federal lands in the United States
Three factors, incorporating seven quantitative indicators, have been selected to represent criteria for prioritization of geothermal areas. These indicators reflect important dimensions for monitoring and estimating the contributions of particular areas to energy production goals on federal lands. Using computerized graphics and data analysis software, weighting of these indicators by experts is integrated to produce a composite indicator for evaluation of leasing activities. The selection of specific indicators for areas which have a high unleased energy potential, where the response of the private sector is positive, and where the potential delay from environmental factors is minimal is described. The development of the composite LAPA indicator and the application of fuzzy set operations for incorporation of expert judgments about the leasing process are also discussed.
