The conceptual design and material study, Task 1 of this project is nearing completion. The primary objective of problem definition, in the form of a preliminary design specification, is complete. Several innovative concepts are being explored and compared. By the end of Task 1, the many alternative concepts will be narrowed considerably so that model studies of the most promising candidates may commence.

RINGBEARER is a particle simulation code for modelling an electron beam propagating in a gas characterized by a space and time varying conductivity generated by the beam. The code has two spatial dimensions, the beam is assumed to be axially symmetric. Equations for the beam driven pinch field, the plasma density, and the conductivity are given along with the appropriate initial conditions and boundary conditions. The equations governing particle energy loss, transverse motion, and scattering, in the beam generated pinch field are presented. The analytic models used in the code are presented with either references or derivations.

Sieve fractionation was performed with oxide particles dislodged during shearing of unirradiated or irradiated fuel bundles or single rods of UO/sub 2/ or 96 to 97% ThO/sub 2/--3 to 4% UO/sub 2/. Analyses of these data by nonlinear least-squares techniques demonstrated that the particle size distribution is lognormal. Variables involved in the numerical analyses include lognormal median size, lognormal standard deviation, and shear cut length. Sieve-fractionation data are presented for unirradiated bundles of stainless-steel-clad or Zircaloy-2-clad UO/sub 2/ or ThO/sub 2/--UO/sub 2/ sheared into lengths from 0.5 to 2.0 in. Data are also presented for irradiated single rods (sheared into lengths of 0.25 to 2.0 in.) of Zircaloy-2-clad UO/sub 2/ from BWRs and of Zircaloy-4-clad UO/sub 2/ from PWRs. Median particle sizes of UO/sub 2/ from shearing irradiated stainless-steel-clad fuel ranged from 103 to 182 ..mu..m; particle sizes of ThO/sub 2/--UO/sub 2/, under these same conditions, ranged from 137 to 202 ..mu..m. Similarly, median particle sizes of UO/sub 2/ from shearing unirradiated Zircaloy-2-clad fuel ranged from 230 to 957 ..mu..m. Irradiation levels of fuels from reactors ranged from 9,000 to 28,000 MWd/MTU. In general, particle sizes from shearing these irradiated fuels are larger than those from the unirradiated fuels; however, …

A detailed description is presented of the analysis of velocity-vs-time data taken with LLL's four-phototube VISAR system. Separate sections deal with a general analysis of on-axis rays when only one frequency of reflected laser light is present, a simplified analysis where two distinct frequencies are present and the rays are still on axis, and a discussion of the effects of off-axis rays. The description is given in such a manner that a VISAR user could employ the formulae in this report to directly analyze data. Unlike previous literature on the VISAR, this analysis does not assume that the mirrors are set at the best fringe contrast position.

At the end is a letter from Haydu to other board members with a list of questions concerning recent events within the organization.

Mechanical properties of various weld configurations for 304 LN stainless steel are reported. The results include Charpy V-notch, tensile, and fracture toughness data. The determinations were made at temperatures of 300, 77, and 4.2/sup 0/K. Each of the three types of mechanical evaluations are treated separately.

A one-dimensional, time-dependent model is described for plasma particle and energy transport and alpha particle transport coupled with magnetic field evolution in a geometry appropriate to EBT. The transport equations used are derived from exact moments of the Boltzmann equation, and the magnetic field is calculated from Faraday's and Ampere's laws. The set of transport equations is closed by incorporating into them transport coefficiencents derived from the appropriate kinetic equation. Also included in the model is a Fokker-Planck calculation of the alpha particle slowing down and resultant plasma heating.

The energy loss of a highly relativistic beam transported in an evacuated pipe of finite conductivity is calculated.

The contract has two phases, a design phase and a fabrication and installation phase. Presented is the work completed in Phase I, the design phase. The Sandia 17 m was used as the background machine from which design information was drawn. By concentrating the modifications on an existing design, emphasis was focused on component cost reduction rather than selection of optimal configuration or operating modes. The resulting design is a stretched version of the Sandia 17 m preserving the same rotor diameter and many other good features, but in the meantime lighter in weight, larger in capacity, and anticipated to be more cost effective.

Increased strengths can be achieved in precipitation-hardened stainless steels by deforming the steel and retaining a worked structure prior to aging. JBK-75 is one example of a superalloy which will respond to this type of thermomechanical processing. The present study was undertaken to determine the tensile properties of different forged shapes resulting from the combined effects of strain hardening and precipitation hardening. Various size bar stock was deformed by High Energy Rate Forging (HERF) and subsequently aged. Resultant tensile properties were quite variable, showing a wide range of strengths and ductilities, well below expected values. The tensile properties were strongly dependent upon forging geometry.

Boral is a cermet of Boron Carbide 'B{sub 4}C' in aluminum clad in aluminum. It is manufactured in rolled sheets using techniques similar to those used in the production of uranium aluminum fuel elements. The core of the standard Boral contains 35% boron carbide by weight. Cladding material is typical 1100 aluminum. Where it is exposed to water in service, the edges of the Boral are recommended by the manufacturer to be clad with aluminum by welding. In Spent Fuel Pool (SFP) racks, the Boral is usually not a structural member but is inserted in cavities between the spent fuel storage positions in the racks. In these locations it is sealed by welding to prevent access of water. Inherently, however, the corrosion of the Boral, both the boron carbide-aluminum cermet and the aluminum cladding, should be minimal in a spent fuel storage pool. The cavities into which the Boral is sealed are typically fabricated of aluminum alloys, i.e. type 6061, or stainless steel. In either case, these are the structural members of the SFP racks. In an SFP, water chemistry tends to be strictly controlled because the SFP water mixes with the reactor coolant during refueling procedures. In SFP's at …

Volume 2 contains appendices as follows: coal supply curves, coal supply model modifications, coal mine financing data, legislative proposals for horizontal divestiture, overview of oil companies in coal industry (including their coal reserves) and the major sources of data and bibliography. (LTN)

The US Congress has set forth proposals which would prohibit oil companies from acquiring coal companies or other non-petroleum energy resources. Some proposals would require oil companies to divest themselves of any such resources that they already hold. The first legislation was introduced on this topic in the 94th Congress and alternative proposals are under serious consideration at the current time. We have analyzed some major variants of these legislative propsals with a study of likely economic behavior in the coal market as a result of horizontal divestiture. After a thorough study of the theoretical and empirical aspects of ownership-related behavior, two dichotomous sets of assumptions are possible. One set of assumptions is oriented towards synergism and growth maximization. The interpretation of these assumptions in the model is one of a lower rate of return for oil owned coal assets relative to non-oil owned assets. The second set of assumptions could broadly be termed monopoly assumptions. The depiction of these within the model framework is one of higher rates of return for oil owned coal relative to non-oil owned. These results are based on economic theory, engineering and econometric models, and analysis; all set in the general framework of comparative …

This energy-impact manual presents information on energy implications of new building design and operation, providing a reasonably accurate means of assessing the total energy impact of new construction in the commercial and residential sectors. While developed specifically for the states of Alaska, Idaho, Oregon, and Washington, much of the data used are national averages; the procedures described are applicable to other regions of the nation, with appropriate adjustments for climatic differences. The manual is organized into three parts, each covering one aspect of the energy impacts of building development. Part I addresses the energy impact of erecting the building(s). This includes the energy cost of grading and excavating and other site preparation. It also takes into account the energy embodied in the fabrication of materials used in building construction, as well as the energy cost of transporting materials to the site and assembling them. Part II focuses on the end use of energy during normal building operation, i.e., the energy consumed for space heating, cooling, lighting, water heating, etc. A simplified calculation sequence is provided which allows the user to estimate the consumption of most combinations of building orientation, characteristics, and operating conditions. Part III examines the relationship of land …

The feasibility of generating additional hydroelectric power from five consecutive existing dams located on the Boardman River in Grand Traverse County and Traverse City, Michigan, was investigated. The potential hydropower production capabilities, in terms of base load power and peak load power, the legal-institutional-environmental constraints, and the economic feasibility, including capital investment, operating costs and maintenance costs, were evaluated for each of the five dam sites individually and as a series of co-dependent facilities. The impact of installing fish passages at each site was analyzed separately. The feasibility assessment utilized the present worth analytical method, considering revenue based on thirty mills/kWh for power, 0.4% general economy escalation rate, and a 6% net income to the municipal utility. The sensitivity of fuel costs increasing at a different rate than the general price-escalation was tested by allowing the increase in fuel costs to vary from 3 to 8% per year. Assuming fuel costs increase at the same rate as the general economy, it is feasible to update, retrofit, renovate, and install hydroelectric generating capacity at Sabin, Boardman and Brown Bridge. Rehabilitation of Union Street and Keystone is also feasible but somewhat less attractive. Operating the dams as a co-dependent system has environmental …
