The recommended EPRI Geothermal Research and Development 5-Year Program Plan has been defined to complement and provide focus for federally sponsored geothermal energy R and D efforts. The scope of the program includes: verification of hydrothermal reservoir capability and low salinity brine heat transfer characteristics at a potential demonstration site followed by design, development and construction of a low salinity hydrothermal demonstration plant in conjunction with an electric utility or utility consortium. Development of a comprehensive set of Guidelines Manuals for use by utility management and engineers spanning the full range of geothermal resource utilization from exploration through plant startup, including not only technical, but environmental, institutional and regulatory factors. A subprogram to define the potential and requirements for Geothermal Systems. A supporting research and technology subprogram oriented toward minimizing the risk associated with utilization of low and high salinity hydrothermal sources. An Advanced Research and Technology subprogram to assess the potential of geopressure resources in conjunction with the Federal government and limited R and D on advanced concepts for utilization of hydrothermal fluids.

Progress is reported for a program to demonstrate by 1976 an experimental gas turbine powered automobile which meets the 1978 Federal Emissions Standards, has significantly improved fuel economy, and is competitive in performance, reliability, and potential manufacturing cost with the conventional piston engine powered, standard size American automobile. Major preparations for engine heat balance tests by NASA were completed. EPA laboratories completed Baseline vehicle emissions, noise, and odor tests. Assembly of the program endurance engine is nearing completion. Test cell evaluation of the government furnished combustor (Solar) verified steady state emissions to be extremely low. Initial engine tests of Vendor A ceramic regenerator cores with an elastomeric drive verified performance predictions. Efforts towards developing a non-nickel oxide regenerator seal show extreme sensitivity to porosity differences between cores of different suppliers. All three preprototype integrated control systems were built. Modifications are being worked out to achieve a stable low speed operation. Two prototype compressor turbine wheels made from the reuseable pattern process are being inspected and processed for testing. The engine housing modified for operation at higher cycle temperatures and pressures was received. The baseline engine converted to free rotor is completing test cell check out. The modified vehicle is ready …

The significant geothermal resource in Texas consists of enormous reservoirs of hot, geopressed water, which formed along the Gulf Coast when water-laden sediments were deposited between surrounding impermeable features, so that the water which would otherwise have been forced out of the sediments was unable to escape. These deposits exist under tremendous pressure created by the weight of the overburden. A geopressure source absorbs heat indirectly, because the geopressured deposits create an insulating barrier that traps and absorbs the thermal energy of the underlying magma. The water from a geopressure source will not be as hot as water from a dry steam or wet steam source, but the quantity available is enormous, and the water pressure itself would be an additional energy source along with the thermal energy. The water may be fresh, or nearly so, and it will contain significant amounts of recoverable methane gas in solution. It may be possible to utilize the water pressure, thermal energy, and the methane gas to generate electricity in small power plants at the recovery site, and the water that has been passed through the turbines and heat exchangers may be a valuable by-product in itself, depending on its quality and regional …

The determination of the leaching rate of radioactive /sup 137/Cs from a cement grout should the grout be contacted by water is necessary for environmental protection. The effect of the leachant turnover rate on /sup 137/Cs leaching rates was evaluated with batch and continuous (modified Soxhlet extractor) modes of experimentation. Three additives (Grundite, potter's clay, and Conasauga shale) were compared in terms of capability of radioactive isotope retention, while two leachants (tap and distilled water) were investigated. The Soxhlet extractor experiment resulted in the highest rate of leaching, and Conasauga shale was found the best additive for /sup 137/Cs immobilization. Tap water used as leachant was more effective than distilled water. Data were analyzed using models involving isotopic diffusion in the grout and involving diffusion plus a time dependent boundary condition at the interface of grout specimen and leachant.

In keeping with Mound Laboratory's tradition for innovation and forward-looking action, several studies were recently conducted to seek out alternatives to incineration and landfill of all nonradioactive solid waste. Efforts were directed towards reclamation, reuse, and recycling of solid wastes. These efforts resulted in a reclamation and recycling program which is being implemented in three separate phases: 1. Phase I provides for reclamation and recycling of IBM cards, printouts, and white paper. 2. Phase II is designed for reclamation, recycling, or off-site disposal of all wastes generated in buildings and areas where radioactive or explosive wastes are not contained. 3. Phase III provides for reclamation, recycling, or off-site disposal of the remaining wastes not included in Phases I and II. Implementatin would follow successful operation of Phases I and II and would only be implemented after a complete analysis of monitoring and segregation techniques have been established to assure against any possibility of off-site contamination.

We propose to design, build and use a tertiary K{sub L}{sup 0} beam produced using the high intensity pion beam being built in the proton area. The main advantage of this beam over previous beam is the low neutron background (K{sub L}/n > 3). We propose to study the large transverse momentum dependence of the particles produced in the strong interactions of a K{sub L}{sup 0} beam, and also the production of leptons, and lepton pairs.

Two years ago the first neutrino interaction had yet to be observed at Fermilab. It was not known at that time whether the cross section would continue to rise above 10 GeV (in fact there were indications from cosmic ray experiments to the contrary), or even whether a W-boson might exist with a mass of say 2.5 GeV/c{sup 2}. Put in this perspective the progress in neutrino physics has been truly outstanding. Let us just review briefly the primary results so far reported by the Caltech-Fermilab group. The physics can be divided into two parts: (A) the study of the structure of hadrons (deep inelastic scattering) and (B) the study of the weak interaction at high energies.

We propose a small exposure (25K pictures) of the hydrogen-filled FNAL 15-foot bubble chamber to a 250 GeV proton beam. Our main physics objectives are: (1) To study the dependence of neutral particle production ({pi}{sup 0}, K{sup 0}, {Lambda}) on the charged multiplicity in diffractive and non-diffractive processes. (2) To measure integrated correlations (f{sub 2}{sup {+-}0} and f{sub 2}{sup 00}) for neutral pions in a ''clean'' experiment. To make these measurements reliably requires neutral particle detection in both CM hemispheres and the CM symmetry of the pp system. For example, we will determine f{sub 2}{sup 00} to {+-} 0.2. The event analysis of the neutral secondaries together with the measurement of the slow laboratory protons in pp {yields} p{sub slow} + X for the distinction between diffractive and non-diffractive events will be done in 1/2 year. Further objectives are: (3) To measure differential neutral-charged correlations. (4) To measure multiplicities, spectra and correlations (''inclusive program'') inside the mass M{sub X} in pp {yields} p{sub slow} + X{sup -}.

Program GEOTHM is a thermodynamic process program now under development for the LBL Geothermal Energy Program. To date, the program development has centered upon the modeling of working fluid properties, developing thermodynamic process models, and modeling the design performance of geothermal power plants. When the program is completed, it will be able to optimize a power plant or refrigeration plant for minimum cost power or refrigeration. Furthermore, operation of the thermodynamic cycles at off design conditions will be able to be simulated. Program GEOTHM is currently able to calculate several types of geothermal power cycles using a wide variety of working fluids.

We propose as the initial experiment in the new dichromatic V detector to make a systematic study of deep inelastic cross sections. This experiment will use the present target-detector remounted. A new magnet spectrometer system will be installed giving both better resolution and acceptance. An improved dichromatic beam will also give better information on the incident 13 neutrino energy. We propose 1000 hours of running with > 10{sup 13} ppp for this experiment.
