UPDATE: nuclear power program information and data, July-September 1981
UPDATE is published by the Office of Coordination and Special Projects, Office of Nuclear Reactor Programs, to provide a quick reference source on the current status of nuclear powerplant construction and operation in the United States and for information on the fuel cycle, economics, and performance of nuclear generating units. Similar information on other means of electric generation as related to nuclear power is included when appropriate. The subject matter of the reports and analyses presented in UPDATE will vary from issue to issue, reflecting changes in foci of interest and new developments in the field of commercial nuclear power generation. UPDATA is intended to provide a timely source of current statistics, results of analyses, and programmatic information proceeding from the activities of the Office of Nuclear Reactor Programs and other components of the Department of Energy, as well as condensations of topical articles from other sources of interest to the nuclear community. It also facilitates quick responses to requests for data and information of the type often solicited from this office.

Development and evaluation of systems for controlling parallel high di/dt thyratrons
Increasing numbers of high power, high repetition rate applications dictate the use or thyratrons in multiple of hard parallel configurations to achieve the required rate of current rise, di/dt. This in turn demands the development of systems to control parallel thyratron commutation with nanosecond accuracy. Such systems must be capable of real-time, fully-automated control in multi-kilohertz applications while still remaining cost effective. This paper describes the evolution of such a control methodology and system.

Measurement of instantaneous shut-in pressure in crystalline rock
A method is defined which was found useful, not only for determining the instantaneous shut-in pressure (ISIP) during fracture creation, but also for determining the pressure inside the fracture, near the exit and entrance wellbores, when a circulation of fluid through a fracture is taking place. The basic assumption of the Muskat method is that, after a short transient period, the shut-in pressure approaches an asymptotic value, Pa, in an exponential fashion, i.e., if Pa is subtracted from P at each time, t, and the result is plotted, ln (P-Pa) vs t will be a straight line. Various values of Pa are tried until the best straight line fit is found. Two Muskat analyses are shown. (MHR)

Hot dry rock geothermal reservoir engineering
Two wells, GT-2 and EE-1, were originally drilled to a depth of 9600 ft (2.93 km) and 10,000 ft (3.05 km), respectively, and, after some difficulties, including redrilling of the bottom portion of GT-2, a good fracture connection was made between EE-1 and GT-2B, as the modified GT-2 was called. The circulation system was studied extensively for the purpose of establishing a number of fracture properties. Techniques were developed to determine orientation, geometry, heat exchange area, volume, flow impedance and impedance distribution. A much larger fracture system was then created from a depth of 9620 ft (2.93 km) in EE-1. The techniques used and results obtained in the study of the new and old fracture systems are discussed.

Development of thin foils for use in generating neutral particle beams
The Isotope Research Materials Laboratory (IRML) was requested to prepare large-area, ultrathin aluminum and carbon foils for use in beam neutralization experiments. There were two major parts to this request. The first was to immediately provide a number of 5-cm-dia foils 5 to 20 ..mu..g/cm/sup 2/ thick for use in experiments at the Fusion Materials Irradiation Test (FMIT) facility and at Argonne National Laboratory (ANL). The second, longer-term request was to develop methods to prepare 25-cm x 25-cm, 10-..mu..g/cm/sup 2/ aluminum neutralizer foils. Both parts of the request have been successfully met.

Inclusive. eta. production in. tau. decays
We have searched for inclusive eta production in tau decays using a sample of 2553 events of e{sup +}e{sup minus} {yields} {tau}{sup +}{tau}{sup minus} in the one-three topology. The data were taken with the High Resolution Spectrometer at {radical}s = 29 GeV. Our results are based on an analysis of the {pi}{sup +}{pi}{sup minus} invariant mass spectrum to find the narrow peak resulting from the decay sequence {tau} {yields} {eta}x and {eta} {yields} {pi}{sup +}{pi}{sup minus}{pi}{degree}. No clear peak is observed and a 90% confidence upper limit on the process {tau} {yields} {eta}x of 2.1% is found. For decays {tau} {yields} {eta}{eta}x the 90% confidence upper limit is 1.3%. Our best limit on {tau} {yields} {eta}{eta}x is obtained from tau decay to five charged particles with a 90% confidence level upper limit of 0.5%.

Limit on tau decay to 7-charged tracks
Using the complete data sample of 300 pb/sup -1/ from e/sup +/e/sup -/ collisions at 29 GeV, the HRS collaboration has searched for tau decay to 7 charged particles and any number of neutrals. No events were found. The corresponding upper limit to the branching ratio is B(tau ..-->.. 7..pi../sup + -/ + n..gamma.. + nu/sub tau/) < 3.8 x 10/sup -4/ at 90% confidence level. Using the final HRS data sample we also report updated branching ratios for tau ..-->.. 5..pi../sup + -/ + nu/sub tau/ and tau ..-->.. 5..pi../sup + -/ + ..pi../sup 0/ + nu/sub tau/.

Search for D/sup *//sup 0/. -->. D/sup +/. pi. /sup -/
We report on a search for the decay mode D/sup *//sup 0/(2007) ..-->.. D/sup +/..pi../sup -/ using the High Resolution Spectrometer at PEP. Although this decay is kinematically forbidden for the central mass value, it can occur through the natural width of the D/sup *//sup 0/. The D/sup +/ was reconstructed in the K/sup -/..pi../sup +/..pi../sup +/ decay mode. The mass difference distribution (K/sup -/..pi../sup +/..pi../sup +/..pi../sup +/) - (K/sup -/..pi../sup +/..pi../sup -/), which shows no threshold enhancement, leads to a preliminary upper limit on the branching ratio of B/sub r/(D/sup *//sup 0/ ..-->.. D/sup +/..pi../sup -/) < 15% at 90% CL. This, in turn, corresponds to an upper limit on the D/sup *//sup 0/ width of 1.5 MeV/c/sup 2/ at 90% CL. 4 refs., 3 figs.

Observation of tensor and scalar mesons produced in e/sup +/e/sup -/ annihilation at 29 GeV
The production of the tensor mesons, integral/sup 0/(1270) and K*/sup 0/(1430), and the scalar meson S(975) have been observed in e/sup +/e/sup -/ annihilation at 29 GeV center of mass energy, using data obtained with the HRS detector at the PEP storage ring. The mean multiplicities for meson momenta greater than 1450 MeV/c are <n/sub f/sup 0//> = 0.11 +- 0.04, <n/sub K*/sup 0/(1430)/> = 0.10 +- 0.06, and <n/sub S/> = 0.05 +- 0.02 per hadronic event. The fragmentation functions of the tensor mesons are in good agreement with the predictions of the Webber cluster model. The possibility of a large strange quark component in the S meson structure is suggested by the data.

Prospects for top at the Tevatron collider in the 1990's
We calculated the signal and background rates for top masses of 90, 120, 150, and 180 GeV for both the CDF and D{null} detectors. This allowed us to determine the prospects for both discovery as well as detailed study of heavy top depending on the luminosity. We have focused on the leptons + jets and dilepton signatures. We also consider the question of tagging b-jets and how that should reduce background and help in making a mass determination. 8 refs., 5 figs., 5 tabs.

The Soviet American Gallium Experiment (SAGE)
A radiochemical experiment using the reaction v/sub e/ = /sup 71/Ga + e/sup e/ to determine the integral flux of low-energy neutrinos from the sun is currently under preparation at the Baksan Neutrino Observatory in the USSR. Measurements are scheduled to commence by late 1988 using /approximately/30 tonnes of metallic gallium. With this amount of gallium it should be possible to obtain a fractional statistical accuracy of 12 to 15% after one year (assuming the standard solar model neutrino flux). While initial measurements are in progress, installation of the remaining 30 tonnes of gallium will proceed in order to perform the full 60 tonne experiment.

The Baksan Neutrino Observatory Soviet-American Gallium Solar Neutrino Experiment
A radiochemical /sup 71/Ga-/sup 71/Ge experiment to determine the integral flux of neutrinos from the sun is currently under preparation at the Baksan Neutrino Observatory in the USSR. Measurements are scheduled to commence by late 1988 with 30 tonnes of metallic gallium. A fractional statistical accuracy of 18% is expected to be obtained after one year of operation if the solar signal obtained after one year of operation if the solar signal is 70 SNU, the flux expected from p-p neutrinos alone. While initial measurements are in progress, 30 additional tonnes of gallium will be installed in order to perform the full experiment with a 60-tonne target. 28 refs.

Role of water in energy development
One consequence of the recently increasing emphasis on energy development is public concern about the adequacy of ancillary natural resources, particularly water. This concern accompanies other water-related issues such as droughts, decling water tables, and increasing urbanization. But as the relatively new user on the water scene, energy attracts a major share of public attention. The physical availabiltiy of water and the role of economics in water demand by energy are reviewed. Also described are the social mechanisms through which the physical availability of water, the historical pattern of water use, and unresolved water issues combine to constrain and channel the energy industry's use of water. These mechanisms include the developing markets for water rights, the legal and administrative structure governing water allocation, the formation of social attidudes about water, and the political process that often implements concensus. The narrow physical interpretation commonly given to the question Is there enough water is broadened to include the social dimension, the most important component of the quenstion.

Review of ORNL-TSF shielding experiments for the gas-cooled Fast Breeder Reactor Program
During the period between 1975 and 1980 a series of experiments was performed at the ORNL Tower Shielding Facility in support of the shield design for a 300-MW(e) Gas Cooled Fast Breeder Demonstration Plant. This report reviews the experiments and calculations, which included studies of: (1) neutron streaming in the helium coolant passageways in the GCFR core; (2) the effectiveness of the shield designed to protect the reactor grid plate from radiation damage; (3) the adequacy of the radial shield in protecting the PCRV (prestressed concrete reactor vessel) from radiation damage; (4) neutron streaming between abutting sections of the radial shield; and (5) the effectiveness of the exit shield in reducing the neutron fluxes in the upper plenum region of the reactor.
