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 Information published in the Texas Register includes proposed, adopted, withdrawn and emergency rule actions, notices of state agency review of agency rules, governor's appointments, attorney general opinions, and miscellaneous documents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.

BREAD will process a family of files copied from a data tape made by Hewlett-Packard equipment employed for data acquisition on the Spent Fuel Test-Climax at NTS. Tapes are delivered to Livermore approximately monthly. The process at this stage consists of four steps: read the binary files and convert from H-P 16-bit words to CDC 7600 60-bit words; check identification and data ranges; write the data in 6-bit ASCII (BCD) format, one data point per line; then sort the file by identifier and time.

During proper operation of the Purex process for the recovery of uranium and plutonium from spent reactor fuel, there are only trace levels of uranium in the aqueous waste. In the event of an upset in the extraction columns the aqueous waste stream would give the first indication of breakthrough. From the standpoint of process control it would be desirable to have an in-line, real-time sensor for uranium in the aqueous waste stream. It was toward this end that this investigation was undertaken. The measurement technique that seems to provide the most sensitive method without addition of reagents appears to be the electrochemical reduction of UO{sub 2}{sup 2+} to U(IV) followed by spectral measurement. The electrochemical reduction to U(IV) increases the sensitivity by a factor of three to five and shifts the measurement wavelength to a spectral area (647 nm and 1075 nm) unaffected by fission products. Using the proposed analysis sequence it is possible to determine uranium at a level of 0.2 g/L in the presence of relatively high spectral background. This report details the electrochemical reduction of U(VI) in nitric acid solutions (0.5 M to 2.0 M) with platinum-vitreous carbon electrodes and examines the spectral behavior of U(IV) …

During the spring of 1982, the National Marine Fisheries Service initiated a multiyear research program to define the effects of river conditions and dam operations on the current system (flow-net) in the forebay of John Day Dam on the Columbia River and to relate smolt passage behavior to the physical characteristics of the flow-net. Twelve digital, magnetic recording current meters were deployed in a grid within the restricted zone adjacent to the dam on 13 May 1982. Current velocity and direction were monitored until 3 November 1982. During this initial year, research efforts focused on gathering the first general data on flows within the forebay of John Day Dam and developing the computer software necessary to ultimately construct the flow-net model.

Laser accelerators may be conveniently characterized, by their mode of operation, into media, far-field, and near-field accelerators. The first category--media accelerators--include the Inverse Cherenkov Effect Accelerator, the Plasma Focus Accelerator, and the Beat Wave Accelerator (BWA). The second category--far-field accelerators--include the Two-Wave Device and the Inverse Free Electron Accelerator (IFEL). The third category--near-field accelerators--includes conventional linacs scaled to small dimensions, dielectric sheets, small holes in dielectric cylinders, and gratings. Attention is devoted to an example from each category: namely (1) the BWA, (2) the IFEL, and (3) the linac scaled to small dimensions (about 30 GHz) and powered by a free electron laser (FEL). Finally, special attention is given to grating accelerators.

The characteristics of the LBL continuous-wave wide-band low-noise preamplifier, version B, have been presented over a frequency range of approximately 1-2GHz. In this preamplifier the source leads of the transistors in the first two stages are soldered directly to copper studs which are attached to the copper enclosure box to get better thermoconductivity. Two sets of noise figures were presented with one set optimized at 3000 K and the other at 18 K. When the N.F. was optimized at 80 K the result was very much the same as the one optimized at l8 K. It was found that different transistors behaved differently Hence individual amplifier must be optimized at the intended operating temperature. The VSWR data presented are those of the room temperature. The change in VSWR at low temperatures are not significantly different from those at room temperature. The output power as a function of input power at various frequencies and their intermodulation products are very much the same at all temperatures. The preamplifier is unconditionally stable with an open or shorted sliding line at the input port.

It is useful before beginning our work here to restate briefly the purpose of this workshop in the light of the present circumstances of elementary particle physics in the U.S. The goal of our field is easily stated in a general way: it is to reach higher center of mass energies and higher luminosities while employing more sensitive and more versatile event detectors, all in order to probe more deeply into the physics of elementary particles. The obstacles to achieving this goal are equally apparent. Escalating costs of construction and operation of our facilities limit alternatives and force us to make hard choices among those alternatives. The necessity to be highly selective in the choice of facilities, in conjunction with the need for increased manpower concentrations to build accelerators and mount experiments, leads to complex social problems within the science. As the frontier is removed ever further, serious technical difficulties and limitations arise. Finally, competition, much of which is usually healthy, now manifests itself with greater intensity on a regional basis within our country and also on an international scale. In the far ({ge}20 yr) future, collaboration on physics facilities by two or more of the major economic entities of …

The BEACON process involves the catalytic deposition of a highly reactive form of carbon from a gas stream which contains carbon monoxide. The carbon-depleted gas is combusted with air to produce power, and the carbon is reacted with steam to produce methane or hydrogen. During the quarter both SOHIO and TRW worked on catalysts which would suppress methane formation during steaming thus increasing the amount of hydrogen formed. At SOHIO a C77-K2 catalyst promoted with a Class II compound showed promise in laboratory tests for suppressing methane. At TRW a K-1 unsupported catalyst promoted with 10% of Additive F maintained methane suppression over 30 cycles in laboratory scale tests. Shakedown of the Tandem Reactor Apparatus was completed and testing was initiated under quasi-continuous transfer of solids between reactors. Nine short term tests were performed with K-1 based BEACON solids. The data from these tests indicate that the Tandem Reactor concept is valid and BEACON solids can be transferred efficiently in the fluidized state between the deposition and gasification reactors. A preliminary analysis of the potential of a BEACON combined cycle/hydrogen system with a hydrogen fuel cell has been performed. The BEACON process can be used to coproduce hydrogen and electric …

Low-temperature measurements of muonium parameters in various germanium crystals have been performed. We have measured crystals with different levels of neutral impurities, with and without dislocations, and with different annealing histories. The most striking result is the apparent trapping of Mu by silicon impurities in germanium.

The BEACON process involves the catalytic deposition of a highly reactive form of carbon from a gas stream which contains carbon monoxide. The carbon-depleted gas is combusted with air to produce power, and the carbon is reacted with steam to produce methane or hydrogen. Catalyst development at SOHIO showed that larger quantities (4 kg) of satisfactory C77-K2 catalyst could be prepared. Several preparation modifications were studied, and, although some showed satisfactory results, none were sufficiently attractive to be adopted. Studies were conducted at SOHIO on promoters for the C77 type catalyst that would increase hydrogen production and suppress methane. Several were found, one of which operates at 550/sup 0/C. The C77-K1 catalyst was found not to be satisfactory for converting oil shale retort off-gas to hydrogen. The C77-K2 catalyst does perform this conversion under economically attractive conditions. Physical characteristics for sieve fractions of a C77-K2 catalyst were determined. A new catalyst support was evaluated and found to be unsatisfactory. Tandem Reactor development proceeded at TRW with completion of construction and the test readiness review and the initiation of shakedown testing. Good fluidization with a C77-K2 catalyst was achieved with the installation of a stirrer in a 1.5-inch reactor at SOHIO. …

Radionuclides from FUSRAP wastes potentially may be taken up by plants during remedial action activities and permanent near-surface burial of contaminated materials. In order to better understand the propensity of radionuclides to accumulate in plant tissue, soil and plant factors influencing the uptake and accumulation of radionuclides by plants are reviewed. In addition, data describing the uptake of the principal radionuclides present in FUSRAP wastes (uranium-238, thorium-230, radium-226, lead-210, and polonium-210) are summarized. All five radionuclides can accumulate in plant root tissue to some extent, and there is potential for the translocation and accumulation of these radionuclides in plant shoot tissue. Of these five radionuclides, radium-226 appears to have the greatest potential for translocation and accumulation in plant shoot tissue. 28 references, 1 figure, 3 tables.

The environmental levels of radioactivity and other pollutants found in the vicinity of BNL during 1982 are summarized in this report. As an aid in the interpretation of the data, the amounts of radioactivity and other pollutants released in airborne and liquid effluents from Laboratory facilities to the environment are also indicated. The environmental data include external radiation levels; radioactive air particulates; tritium concentrations; the amounts and concentrations of radioactivity in and the water quality of the stream into which liquid effluents are released; the concentrations of radioactivity in biota from the stream; the concentrations of radioactivity in and the water quality of ground waters underlying the Laboratory; and concentrations of radioactivity in milk samples obtained in the vicinity of the Laboratory. 30 references, 9 figures, 18 tables.

We report new limits on right-handed currents, based on precise measurement of the endpoint of the e/sup +/ spectrum from ..mu../sup +/ decay. Highly polarized ..mu../sup +/ from the TRIUMF surface beam were stopped in pure metal foils within either an 1.1-T spin-holding longitudinal field, or a 70-gauss spin-precessing transverse field. Decay e/sup +/ emitted within 200 mrad of the beam direction were momentum-analyzed to +-0.2%. For the spin-held data, decay via (V-A) currents requires the e/sup +/ rate to approach zero in the beam direction at the endpoint. Measurement of this rate sets the 90% confidence limits xi P/sub ..mu../delta/rho > 0.9959 and M(W/sub R/) > 380 GeV, where W/sub R/ is the possible right-handed gauge boson. For the spin-precessed data we independently determine a 90% confidence limit xi P/sub ..mu../delta/rho > 0.9918. 18 references.

This report documents the California Energy Commission's administration of its Geothermal Development Grant Program for Local Governments. The Energy Commission established this program as a result of the passage of Assembly Bill 1905 (Bosco) in 1980. This legislation established the mechanism to distribute the state's share of revenues received from the leasing of federal mineral reserves for geothermal development. The federal government deposits these revenues in the Geothermal Resources Development Account (GRDA) created by AB 1905. The state allocates funds from the GRDA to the California Parklands and Renewable Resources Investment Fund, the counties of origin where the federal leases are located, and the Energy Commission. The legislation further directs the Energy Commission to disburse its share as grants to local governments to assist with the planning and development of geothermal resources. Activities which are eligible for funding under the Energy Commission's grant program include resource development projects, planning and feasibility studies, and activities to mitigate the impacts of existing geothermal development.

The chromoelectric flux tube model is used to obtain a dynamical description of the evaporation of mesons from a quark-gluon plasma. The radiation pressure is computed to assess whether this process is an important mode for the disassembly of a compressed plasma. A new result for the creation rate of q anti q pairs in a constant color field is employed.
