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.

The principal purposes of this report are: (1) identification of the jurisdiction areas of the Federal pipeline-regulating agencies, and (2) examination of 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: (1) use of a ''national equivalent value'' in the economic tradeoff analyses which justify entry of a technological innovation into the rate base (valuation), and (2) 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 …

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.

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.

A weekly publication, the Texas Register serves as the journal of state agency rulemaking for Texas. Information published in the Texas Register includes proposed, adopted, withdrawn and emergency rule actions, notices of state agency review of agency rules, governor's appointments, attorney general opinions, and miscellaneous documents such as requests for proposals. After adoption, these rulemaking actions are codified into the Texas Administrative Code.

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 parametric design study of the tandem mirror reactor (TMR) is described. The results of this study illustrate the variation of reactor characteristics with changes in the independent design parameters, reveal the set of design parameters which minimizes the cost of the reactor, and show the sensitivity of the optimized design to physics and technological uncertainties. The total direct capital cost of an optimized 1000 MWe TMR is estimated to be $1300/kWe. The direct capital cost of a 2000 MWe plant is less than $1000/kWe.

Addition of minute amounts of oxygen to a thermionic energy converter results in a significant performance improvement. The presence of oxygen reduces the collector work function and decreases the cesium pressure required to obtain a given current density from the emitter. In addition, oxygen additive diodes have the practical benefits of increased interelectrode spacing and improving converter power density and efficiency with polycrystalline electrodes. The motivation for the studies described was to provide insight into the activation processes by characterizing the chemical and physical structures of the tungsten oxide collector surfaces from four thermionic diodes in different states of activation: initial, preactivated, activated, and post-activated. The primary tool for these investigations was Electron Spectroscopy for Chemical Analysis (ESCA) with sputtering capability, which provided chemical composition information as a function of distance through each of the tungsten oxide layers. This study has resulted in several important insights into the activation mechanisms. First, converter performance is correlated with layer thickness and with the oxygen concentration. Second, deconvolution of the ESCA spectra shows that four oxidation states of tungsten (0, +2, +4 and +6) are present at all stages of activation. Third, the cesium distributions indicate that this element is present throughout the …

Reports and articles on decommissioning have been reviewed to determine the current technology status and also attempt to identify potential decommissioning problem areas. It is concluded that technological road blocks, which limited decommissioning facilities in the past have been removed. In general, techniques developed by maintenance in maintaining the facility have been used to decommission facilities. Some of the more promising development underway which will further simplify decommissioning activities are: electrolytic decontamination which simplifies some decontaminating operations; arc saw and vacuum furnace which reduce the volume of metallic contaminated material by a factor of 10; remotely operated plasma torch which reduces personnel exposure; and shaped charges, water cannon and rock splitters which simplify concrete removal. Areas in which published data are limited are detailed costs identifying various components included in the total cost and also the quantity of waste generated during the decommissioning activities. With the increased awareness of decommissioning requirements as specified by licensing requirements, design criteria for new facilities are taking into consideration final decommissioning of buildings. Specific building design features will evolve as designs are evaluated and implemented.
