Method of measuring the polarization of high momentum proton beams. [Primakoff effect, asymmetries]
A method of measuring the polarization of high momentum proton beams is proposed. This method utilizes the Primakoff effect and relates asymmetries at high energy to large asymmetries already measured at low energy. Such a new method is essential for the success of future experiments at energies where present methods are no longer feasible.

Fission product data for thermal reactors. Part 2. Users manual for EPRI-CINDER code and data
The objective of this project has been the production of a data library suitable for calculating the buildup of fission product nuclides during the operation of a thermal power reactor. This has been accomplished by reducing the fission product data from the fourth version of the national reference nuclear data base--ENDF/B into a series of linearized decay chains and calculating the effective yields and cross sections of the relevant nuclides. Two versions of the fission product library have been prepared: an 84 chain master library and a reduced 12 chain library, both of which can be used as input for the computer program CINDER. A users manual for an upgraded version of the burnup program CINDER (renamed EPRI-CINDER) is presented.

Comments on mutagenesis risk estimation
Several hypotheses and concepts have tended to oversimplify the problem of mutagenesis and can be misleading when used for genetic risk estimation. These include: the hypothesis that radiation-induced mutation frequency depends primarily on the DNA content per haploid genome, the extension of this concept to chemical mutagenesis, the view that, since DNA is DNA, mutational effects can be expected to be qualitatively similar in all organisms, the REC unit, and the view that mutation rates from chronic irradiation can be theoretically and accurately predicted from acute irradiation data. Therefore, direct determination of frequencies of transmitted mutations in mammals continues to be important for risk estimation, and the specific-locus method in mice is shown to be not as expensive as is commonly supposed for many of the chemical testing requirements.

Feasibility of developing low-cost measures of demand for public transportation in rural areas. Final report
The Appalachian region has many rural areas of limited accessibility. To improve the accessibility of the rural carless (poor, elderly, young, infirm) public transportation has often been suggested. The objective of the research is to develop a low-cost methodology for determining latent demand for public transportation in rural areas, i.e., to develop a data base of key socio-economic, highway network, and geographic variables which can be used to estimate latent demand along possible rural-transit routes. Data were collected on existing rural-transit operations in Planning Region VI of West Virginia (Monongalia, Taylor, Marion, Harrison, Doddridge, and Preston counties) by means of an on-off survey and an on-board questionnaire survey. Using these as indicators of demand, this information will be related to census data for the affected region to determine if a simplified modeling approach to estimate rural public transportation demand is feasible.

Semi-annual report on the project to design and experimentally test an improved geothermal drill bit, Phase II
The test facilities (the geothermal drilling vessel and the geothermal drill-bit seal tester) were completed and de-bugged, and the first tests were run on full-scale research drill bits and drill-bit seals. In addition, more materials information was gathered, and a number of additional seals of high-temperature elastomer materials were obtained for testing. Maurer Engineering has also been active in the design and procurement of candidate high-temperature drill-bit seals for testing, and has done a literature and patent search on the problem of drill-bit insert retention. Reed Tool Co. has cooperated in the fabrication of drill bits for testing, and has offered consultation on certain seal designs.

Stimulated Raman scattering at kHz-pulse-repetition rates. Quarterly report, 10 August 1976-10 November 1976. [LiIO/sub 3/ and LiNBO/sub 3/]
Experiments have been carried out on the two-mirror configuration of a LiIO/sub 3/ Raman oscillator. With the two-mirror setup, 1.0 watt average power was obtained in the 1.18 ..mu..m 1st Stokes line and 550 mW in the 1.31 ..mu..m 2nd Stokes line. Both of these represent new records for SRS. The two-mirror configuration has very stable outputs and is probably superior to the three-mirror configuration for most applications. In addition, mode-locked operation of the two-mirror Raman oscillator has been demonstrated. SRS was obtained with the 628 cm/sup -1/ mode in LiNbO/sub 3/ for the first time at kHz prf's. In our initial experiments, the SRS is weak and difficult to maintain. Several factors have been identified which are likely responsible for the relatively poor performance of this Raman oscillator.

Ultra purification of metals by electrotransport under outer space environmental condition. Final report, April 1, 1974--September 30, 1976. [2 x 10/sup -12/ torr]
A space simulation chamber capable of achieving pressures of 2 x 10/sup -12/ torr (N/sub 2/) was designed, fabricated, and used to develop a preprototype electrotransport experiment. It was demonstrated that the electrotransport purification of refractory metals could be successfully performed in the noncontaminating environment of an orbiting low-density materials laboratory such as the Molecular Shield Device. The zero gravity of outer space will also be advantageous since ''grain-sliding'' will be eliminated. As a result of the various experiments, small quantities of the world's purest thorium metal were prepared and evaluated. The electrotransport sample assembly was tested in several environments including near-zero gravity, simulated solar radiation, coldness, and darkness, and under various pressures of a representative reactive gas. Ultrapure single crystals of ..cap alpha.. thorium were prepared and are presently being characterized. Laboratory electronics for the experiment were also developed, and a totally automatic control system was used to heat the specimen. Complete assembly and line drawings of the components of the experiment and specifications for a high-current power supply are contained in the appendices.

Design of the US-CRBRP sodium/water reaction pressure relief system
Protection against intermediate sodium system overpressure from the sodium/water reaction associated with large leaks within the CRBRP Steam Generators is provided by the sodium/water reaction pressure relief system (SWRPRS). This system consists of rupture disks connected to the intermediate sodium piping adjacent to the inlet to the superheater and outlet from the evaporator modules. The rupture discs relieve into piping that leads to reaction produce separator tanks, which in turn are vented to a centrifugal separator and flare stack arranged to burn hydrogen gas exhausting into the atmosphere. Analyses have been conducted using the TRANSWRAP Computer Code to predict the system pressures and flow rates during the large leak event. Experimental tests to be conducted in the large leak test rig (LLTR) will be used to confirm the analysis techniques used in the design.

Issues in the future supply of electricity to the Northeast. [1985 and 2000]
This assessment of the problems of the electric sector is part of the BNL study on the Energy Future of the Northeast. Topics covered by the issue papers include the potential supply of energy to the Northeast from coal, oil, natural gas, liquefied natural gas, nuclear power, municipal waste, solar energy, and wind power, and the demand for energy in the Northeast from the industrial, transportation, and residential and commercial sectors. This paper compares energy demand projections derived in other parts of the Northeast Energy Perspectives Study to current utility projections; discusses major technical issues in capacity forecasting, including system load factors, outage rates, scale economies, unit sizes, and generation mix planning; discusses major siting constraints faced by each type of generation in the Northeast; and prepares preliminary forecasts of the number and type of new generation facilities necessary by 1985 and 2000, and an analysis of the implications for regional siting policy.

Development of a prototype high temperature amplifier for geothermal well logging. Final report
A high temperature amplifier for use in geothermal well logging was developed. This development was based on the use of ceramic vacuum tubes as the active circuit element, since these tubes have the capability to operate in the high ambient temperature environment. The primary goal of this program was to design, build, and deliver a prototype amplifier capable of continuous operation in a 250/sup 0/C environment. A development program designed to meet this goal covered four phases. These phases were (1) development of the basic circuit configuration with conventional, low cost glass envelope vacuum tubes; (2) modification of the circuitry to accommodate the ceramic vacuum tubes; (3) a 1000-hour duration temperature cycle (48 hours at 260/sup 0/C and 2 hours at 20/sup 0/C); and (4) development of a prototype, deliverable amplifier. The following sections discuss the high temperature amplifier development program. Section 2 describes the amplifier performance, including design requirements, circuit design, development program, and the prototype amplifier. Section 3 presents test results from two breadboard models, one with conventional glass tubes and one with ceramic tubes, and the prototype amplifier. Section 4 describes the operation of the prototype amplifier. Circuit equations used for analysis and tube characteristics are contained …

Thermal loop experimental facility, Salton Sea geothermal field, Niland, California: Environmental assessment
The US Energy Research and Development Administration (ERDA) has negotiated a contract with San Diego Gas and Electric Company, San Diego, California, (SDG and E) to support and expedite technology development at thermal loop experimental facility already under construction by SDG and E in the Salton Sea Geothermal Field, near Niland, Imperial Valley, California. The facility is designed to simulate a 10 MWe geothermal electrical power plant, using 4-stage steam flash and binary cycle conversion equipment to extract heat from the high-temperature, high-salinity geothermal brines of the Salton Sea Field. An expansion valve will be used to simulate a power turbines to evaluate system operation. To date, economic development of this geothermal resource has been inhibited by severe technical problems, primarily scaling buildup in equipment exposed to the highly concentrated brines. As a result of test conducted during the past several years, SDG and E has designed a heat transfer system which, if successful, will permit utilization of this resource.

Feedback as a means of decreasing residential energy consumption. Report PU/CES 34
When residential units are analyzed in human factor terms, it is apparent that the consumption level feedback (typically a bill, calculated once a month, over all appliances) is inadequate to give the resident useful information about his energy consuming actions. The present study tested the hypothesis that providing immediate feedback to homeowners concerning their daily rate of electric usage would be effective in reducing electric consumption. In the studied homes, central air-conditioning is the largest single source of electric power consumption during the summer. Accordingly, it was possible to predict the household's expected electric consumption in terms of the average daily outdoor temperature. Predicted electric consumption was derived from a previous month's modeling period during which a regression line was fitted to predict consumption from average daily temperature, for each home. Feedback was expressed as a percentage of actual consumption over predicted consumption. Feedback was displayed to homeowners four times a week for approximately one month. The results confirmed the prediction. Before feedback began, the feedback and control groups were consuming electricity at approximately equal rates. During the feedback period, the feedback group used 10.5 percent less electricity. The effectiveness of the feedback procedure was explained in terms of its …

Characterization of ESR and VAR 2-1/4Cr--1Mo alloy tubing. [LMFBR]
Commercial tubing for LMFBR sodium-water steam generator applications was produced from ESR and VAR 2/sup 1///sub 4/Cr--1Mo alloy (Grade T22) and characterized regarding chemical composition, microstructure, physical characteristics, and short and long term mechanical properties. These results demonstrate that tubing meeting RDT Standard RDT M3-33 can be produced from either the ESR or VAR process and is acceptable to ASME Code Section III requirements. Metallurgical and mechanical properties are similar for both ESR and VAR material, indicating that either remelting practice is acceptable.

High-burnup performance of mixed-oxide fuel rods clad in type 316SS of 0. 010- and 0. 015-inch wall thickness. [LMFBR]
Two short mixed-oxide fuel rods of LMFBR design configuration were irradiated to a burnup of approx. 12.5 atom % in GETR. Profilometry at several intervals during the test indicated that the rod with a 0.010 inch thick cladding exhibited a diametral strain of 0.17% per atom % burnup, while the rod with a 0.015 inch thick cladding exhibited a lower diametral strain rate of 0.12% per atom % burnup. These data present the opportunity for analytical methods to evaluate fuel rod dimensional changes without the complicating effect of metal swelling. Also, the rods incorporated a large plenum space so that pressure from released fission gases was extremely low. These measured strain rates are consistent with the range of fuel diametral strain rates that are associated with solid fission product swelling.

Source terms for radioactive gaseous effluents from a model high-level waste solidification facility
The model high-level waste solidification facility (WSF) is envisaged as being similar to the New Waste Calcining Facility (NWCF) being constructed at the Idaho National Engineering Laboratory but with provisions for incorporating the calcine into a glass. The decontamination factor (DF) is estimated to be one for tritium, 100 for iodine, and 5.0 x 10/sup 8/ for ruthenium. The DFs for other nuclides are in the range of mid to high 10/sup 9/. The volatile radionuclide of primary concern in waste solidification is ruthenium (in particular, /sup 106/Ru). With an estimated DF of 5.0 x 10/sup 8/, the /sup 106/Ru expected to be released from the WSF amounts to 3.4, 2.9, and 0.091 mCi/day for immediate solidification, a freshly filled waste tank (189 days), and five years of tank storage, respectively. The FSAR of the Barnwell Nuclear Fuel Plant Separations Facility implies that 4.6 mCi/day of /sup 106/Ru might be released from the stack of the separations facility and states that such a release meets all state and Federal standards and specifications.

Heat-flow data from southeastern Oregon
With the exception of values from two holes drilled within 2 km of Mickey Hot Springs, 17 new heat-flow values in southeastern Oregon are within or somewhat below the range one would normally expect in nonanomalous parts of the North American Cordillera. This is not surprising for a region in which most igneous rocks on the surface are 5 m.y. old or more. There is a suggestion of a thermal anomaly associated with the very young (late Pleistocene or Holocene) Diamond Craters lava field, and the thermal regime on both sides of Steens Mountain seems to be controlled, to some degree, by lateral and vertical movement of water.
