A stress analysis was performed on the LOFT pressurizer surge line (hereafter called the surge line) to determine if it met the requirements of the ASME BPV Code Section III, for Class 1 components. Dead weight, thermal expansion, seismic, design LOCE and LOCA loads were considered. After the addition of restraints (specified in letter, HIK-12-75, ''LOFT Pipe Hanger Requirements on Main Feed, Main Steam, Pressurizer, and ECC Systems,'' Nov. 24, 1975) the primary and secondary stress levels were found to be acceptable.

Atomics International and Lawrence Livermore Laboratory are involved in the conceptual design of a laser fusion power plant incorporating the lithium fall target chamber. In this paper we discuss some of the more important design considerations for the target chamber and evaluate its nuclear performance. Sizing and configuration of the fall, hydraulic effects, and mechanical design considerations are addressed. The nuclear aspects examined include tritium breeding, energy deposition, and radiation damage.

Cold trap requirements for the Primary Heat Transfer System (PHTS) and the Intermediate Heat Transfer System (IHTS) are defined. The bases for these requirements are (1) maintaining concentrations of oxygen and hydrogen within given limits, (2) controlling the transport of tritium by coprecipitating it in cold traps together with hydrogen, and (3) providing the necessary volume capacity for collecting impurities. It is concluded that the 60 gpm, FFTF Type I, NaK cooled, cold trap will satisfy the PHTS requirements. For each of the IHTS loops a single, 60 gpm, cold trap is required; and an aircooled trap similar to the FFTF Type I design except for a 3-foot longer crystallizer section has been chosen for this service.

A standard procedure for the determintion of the minority carrier diffusion length by means of a scanning electron microscope (SEM) consists in scanning across an angle-lapped surface of a P--N junction and measuring the resultant short circuit current I/sub sc/ as a function of beam position. A detailed analysis of the I/sub sc/ originating from this configuration is presented. It is found that, for a point source excitation, the I/sub sc/ depends very simply on x, the variable distance between the surfce and the junction edge. The expression for the I/sub sc/ of a planar junction device is well known. If d, the constant distance between the plane of the surface of the semiconductor and the junction edge in the expression for the I/sub sc/ of a planar junction is merely replaced by x, the variable distance of the corresponding angle-lapped junction, an expression results which is correct to within a small fraction of a percent as long as the angle between the surfaces, 2 theta/sub 1/, is amaller than 10/sup 0/.

Following a recent IEA meeting of steel industry experts held in Stockholm in May 1979, a number of specific projects have been recommended as forming the basis for a cooperative program of R and D oriented to energy saving in the making of iron and steel. A timetable of work leading up to another meeting (October-November 1979) has been agreed, and this includes the development of detailed project descriptions, as well as the drafting of a proposed implementing agreement with its technical annexes. In summary, five working areas have been identified: surface inspection, surface conditioning, heat recovery, energy conversion and combustion, and material properties. A total of about 20 projects have been suggested, and it is hoped that sufficient detail will be provided on most of these to allow an acceptable implementing agreement to be developed within the next six months.

The principal purposes of this report are to identify the jurisdiction areas of the federal pipeline regulating agencies, and to examine the amenability of the regulatory system to the introduction of energy-conservative new technology into the pipeline industry. The history, scope, and agency structure of state and federal regulation are recounted and some gaps, overlaps, and ambiguities are identified. The only significant inhibitory effects upon technological innovation are found to derive from the FPC and ICC limits upon profit, the 1941 Justice Department consent decree limiting dividends to shipper-owned pipelines, and the income tax rules governing recovery of investment credits and startup losses. Effects of these limits are explored by simulation studies using the Systems, Science and Software pipeline economic model (PEM). Two new concepts of regulation are proposed which would neutralize the inhibitory effect of the present regulatory system and would motivate pipeline operators to conserve energy: one, the use of a national equivalent value in the economic trade-off analyses which justify entry of a technological innovation into the rate base (valuation); and two, a valuation allowance which would reverse the presently often-existing situation and insure that the pipeline operator would realize a greater profit from saving energy than …

Progress in the design and development of a continuously variable ratio transmission for an automotive vehicle is reported. The Major automotive hydromechanical transmission development problem continues to be the reduction of hydrostatic noise and the project plan, therefore, concentrated on the new hydrostatic module. The potential for achieving acceptably low noise levels in the second generation hydromechanical transmission is to be assessed by comparing the noise levels of the hydrostatic modules for the first and second generation transmissions. A set of twelve test points was selected comprising of road load steady state and wide-open-throttle acceleration at 10, 20, 30, 40, 50 and 60 mph. The module operating conditions for the two transmissions at each of these twelve points were calculated. Baseline noise data was measured on the first generation module. The results are given testing of co-axial hydrostatic module for second generation hydromechanical transmission will be emphasized. (LCL)

The Division of Solar Technology of the Department of Energy is currently examining the market potential of a number of dispersed solar energy systems, including the small (less than or equal to 10 MW/sub e/) solar thermal power system. Small fossil-fueled generating units in the United States utility system, (i.e., investor-owned, municipal, and cooperatives) have a current capacity of approximately 8000 MW/sub e/ or about 1.5 percent of the total US electrical capacity, and provide a large potential market for small solar thermal power systems. The Small Power Systems Study has as its objective the determination of conditions under which small (less than or equal to 10 MW/sub e/) solar thermal power units can provide cost-effective electrical power to a variety of users. Potential users, in addition to the utility systems; include Department of Defense installations and applications, remote mining and/or lumbering operations, and other industrial power systems with and without cogeneration. The first year's results on the Small Power Systems Study are summarized. The data base used and the breakeven cost analysis are discussed. Information on both small (less than or equal to 10 MW/sub e/) generating units and the utility systems using them is presented as well as …

In February 1976, the US Energy Research and Development Administration expanded the commercial radioactive waste management programs and established the National Waste Terminal Storage Program. Its mission was to provide multiple facilities in various deep geologic formations within the United States. The Office of Waste Isolation was established within the Union Carbide Corporation-Nuclear Division to provide program management to the National Waste Terminal Storage Program. The overall program consisted of investigating a number of geologic rock types to determine their suitability for terminal storage of radioactive waste. Basalts, such as the Columbia Plateau basalts which underlie a large portion of the Pacific Northwest and the Hanford reservation, were selected for initial geologic reconnaissance. Atlantic Richfield Hanford Company was asked in May 1976 by the Office of Waste Isolation to plan and execute a basalt feasibility study. Geologic exploration of Columbia Plateau basalts was needed to determine the feasibility of utilizing those formations as a site for terminal storage of commercial nuclear waste. In September 1977, the National Waste Terminal Storage Program was restructured. While emphasis was still on a salt repository, additional funds were given to support investigations of two US Department of Energy sites (Hanford and Nevada). Rockwell Hanford …

This study is part of a larger research effort to project U.S. energy demand and energy prices by state from 1985 to 2015; these projections will be used to assess the potential penetration into the U.S. energy economy by specific solar systems. The detailed agricultural energy price forecasts for the 1985-2015 period used by The Aerospace Corporation to assess the market potential of solar-powered irrigation system is presented. Energy price forecasts in constant 1977 dollars are presented by aggregated county regions in the six states for four major sources of energy used in pumping of irrigation water: liquid petroleum gas (LPG), diesel fuel, natural gas, and electricity.

One of the most difficult technology problems in an inertially confined fusion reactor is the survival of the structure from the repeated stresses caused by the microexplosion products. To mitigate the damage from the microexplosion products, a thick lithium fall can be circulated in front of the structure. This fall will absorb the short-ranged products and moderate and attenuate the neutrons. This paper discusses the response of the fall to the microexplosion products, and estimates the resulting loading and stresses in the first structural wall.

Research was expanded to the drilling of crystalline rock. Advance rates of 40 inches per minute have been achieved at 16,000 psi, 10 gpm flow rate in a 30,000 psi compressive strength rock using the water alone as the drilling mechanism. The quality of the hole achieved as the jet drilled a variety of rock was found to vary and a hydromechanical drilling bit, combining high pressure water jets with roller cones, has been developed. A field drilling unit has been tested and modified to allow the drilling of holes to 3/sup 1///sub 2/ inch diameter using the hydromechanical drill. Preliminary work on the development of a cavitation test for rock is also included.

Geothermal energy development research at the Lawrence Livermore Laboratory through 1976 has been aimed at solving the problems associated with the use of high-temperature, high-salinity brines found in the Salton Sea Geothermal Field for their practical conversion to electrical energy. Specifically, part of the program has been oriented toward solving the problems of scale and solids deposition and corrosion of system components that are exposed to the highly mineralized brines. Brine acidification was found to be a promising method for controlling scale and solids deposition. Titanium, zirconium, and chromium-molybdenum alloys were shown to be the best economical corrosion-resistant materials for use in various parts of a total-flow turbine system. Scale and solids control and materials tests for conversion systems based on brine flashing are currently being evaluated. Some initial results and test plans are discussed.

The particle beam parameters needed for inertial fusion can be achieved with conventional accelerator technology if heavy ion machines attain the level of performance of the most intense high energy proton machines. Many of the problems posed by this goal pertain to the low energy portions of the accelerator system. In particular, the implied particle current in the rf linac is 10/sup 3/--10/sup 4/ times the values achieved with existing heavy ion machines. Much of this discrepancy is simply attributable to the great differences between the design considerations relevant to accelerators for fusion and those which have determined the performance of the existing machines. The basic concept chosen at Argonne National Laboratory is cavities containing single drift tubes mounted on lambda/4 supports. Such structures pose the least problem for the beam transport system, and one cavity is placed between adjacent quadrupole magnets. The average voltage gain of the first cells of the low velocity section is moderate; and, although probably acceptable and improved by the end of the 10 MV section, the low initial gain adds to the motivation provided by the transport problem to increase the preinjector voltage substantially above 750 kV.
