The purpose of this report is to compare the deflection results obtained by the finite element analysis of the CDF yoke and endplug with results arrived at by conventional analytical means. The analyzed structures are shown. The source for the closed form solutions is Formulas for Stress and Strain, by Raymond Roark and Warren Young. The tabulated comparisons of four deflections are given. Following the table are the details of the calculations.

Cemented tungsten carbides with a binder level in the range of 5 to 6 percent exhibited the best resistance to erosion for this class of materials. Other practical cermet meterials were diamond - Si/SiC, Al/sub 2/O/sub 3/-B/sub 4/C-Cr, and B/sub 4/C-Co. SiAlON exhibited erosion resistance equivalent to the best WC-cermet. The only coating system to show promise of improved erosion resistance was CVD TiB/sub 2/ on cemented TiB/sub 2/-Ni. Cracking and/or spalling of a TiC coating and a proprietary TMT coating occurred in the standard slurry erosion test. Ranking of cemented tungsten carbide materials in the laboratory erosion test was the same as that found in service in the Wilsonville pilot plant. Specimens from the Fort Lewis pilot plant which performed well in service exhibited low erosion in the laboratory test. A substitute slurry, was found to be 2 to 4 times more erosive than the coal-derived slurry 8 wt% solids. Ranking of materials in the substitute slurry was nearly identical to that in the coal-derived slurry. Three modes of erosion were: ductile cutting; elastic-plastic indentation and fracture; and intergranular fracture. Erosion of a given material was closely related to its microstructure. In the substitute slurry, the angle-dependence of erosion …

Glass-fabric-filled epoxies irradiated at 4.7 K and examined at room temperature by 20x stereomicroscopy showed an internal flaw structure which increasingly filled the sample as the ..gamma..-dose was increased. These flaws were determined to be areas where the plastic had debonded from the glass fibers. The extent of this process correlated well with the dose-dependent loss of mechanical strength. Evidence is reported for a similar mechanism in polyimides although visible flaws have not yet been produced. Possible mechanisms for debonding are suggested. New experiments are also suggested to clarify further the failure mechanism.

These studies showed that loading the permanently charged filters with captured aerosols will lead to a neutralization of the filter charge. The transfer from the captured aerosol to the fiber surface and the subsequent neutralization of fiber charge. The increased efficiency is due to the additional mechanical capture by the particle deposits. The minimum efficiency obtained during the loading of solid aerosols is determined by the aerosol charge, with highly charged aerosols producing a lower minimum. Permanently charged filters lose their fiber charge when exposed to organic solvents or ionic water solutions. The fiber charge neutralization was minimized by coating the charged fibers with a polymer. Several different coating techniques were examined. Unfortunately, preventing the neutralization of fiber charge is not sufficient to prevent a deterioration of filter efficiency.

The U.S. Interagency Geothermal Coordinating Council was a multi-agency group charged with identifying and reducing barriers to geothermal energy development in the U.S. Many of the issues covered related to regulations for and progress in the leasing of Federal lands in the West for power development. The IGCC reports are important sources of historical information. This has a good list of non-competitive geothermal leases of federal land at the end of FY 1981. By this time, 1.6 million acres had been leased in Nevada alone, and 3.4 million acres total. It turned out later that many of these lease had been used by the Hunt brothers as security for loans they used to attempt to corner the silver market in the U.S., so the amount leased is a statistical aberration with respect to the U.S. geothermal industry's legitimate interest in some of these areas.

In keeping with a mandate from the US Congress to provide opportunities for consumer education and information and to seek consumer input on national issues, the Department of Energy's Office of Consumer Affairs held a three-hour educational forum on the proposed nuclear waste disposal legislation. Nearly one hundred representatives of consumer, public interest, civic and environmental organizations were invited to attend. Consumer affairs professionals of utility companies across the country were also invited to attend the forum. The following six papers were presented: historical perspectives; status of legislation (Senate); status of legislation (House of Representatives); impact on the legislation on electric utilities; impact of the legislation on consumers; implementing the legislation. All six papers have been abstracted and indexed for the Energy Data Base.

Thin film interference coatings are a commonplace addition to surfaces polished in a modern optical fabrication facility. These coatings can have a dramatic effect on the optical performance of the optical component to which they are applied. In this presentation, those effects which are related to polarization of the incident beam or the phase shift difference on reflection (retardation) are discussed.

A simple model gave utilized for calculation of magnetization effects on ac loss and sextupole for Energy Doubler dipole magnets. The calculation in the simple model gave an underestimation of ac loss by about 30%. Results of computation on ac harmonics were also described.

The project involved the installation of water-to-air heat pump heating/cooling systems in three structures at Leroy Percy State Park. The three structures include the Assistant Manager's residence, Cabin No. 1 and Cabin No. 2. The project is now completed and the three structures are successfully heated by the natural hot artesian water source and are cooled by cold water available from the park's water system.

The Super System Code (SSC), coupled with the MINET (Momentum Integral Network) Code, was used to determine the plausibility of these postulated plant conditions, particularly with regard to whether the heat exchangers have sufficient heat transfer area for these conditions to prevail. The SSC/MINET representation of the Clinch River Plant used for the part load study is shown. SSC was used to analyze the reactor, the primary loop, and most of the intermediate loop. MINET was used for the rest of the CRBRP system. The analysis relies primarily on energy balances (SSC), an established package of heat transfer correlations (SSC and MINET), and two steady state momentum integral network solvers (MINET).

The Continental Scientific Drilling Program (CSDP) data base maintained at Lawrence Livermore National Laboratory is funded by the Office of Basic Energy Sciences of the Department of Energy. It is a central repository of information concerning approximately 1800 government funded and scientifically interesting drill holes in the United States. This data base can help reduce drilling costs and maximize scientific value of drilling efforts of government agencies and industry. The services of the CSDP data base are free of charge and available to all.

Thermal-Hydraulic Test Facility (THTF) Test 3.05.5B was conducted by members of the ORNL PWR Blowdown Heat Transfer Separate-Effects Program on July 3, 1980. The objective of the program is to investigate heat transfer phenomena believed to occur in PWRs during accidents, including small and large break loss-of-coolant accidents. Test 3.05.5B was designed to provide transient thermal-hydraulics data in rod bundle geometry under reactor accident-type conditions. Reduced instrument responses are presented. Also included are uncertainties in the instrument responses, calculated mass flows, and calculated rod powers.

This note lists some of the possible causes of beta limitation in tokamak and discusses what is known and what is involved in investigating them. The motivation for preparing this note is the observed degradation of confinement with increasing beta poloidal ..beta../sub p/ and beam power P/sub b/ in ISX-B.
