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.

Radiological and Environmental Research Division ecological annual report, January-December 1975. [Transuranium elements, plutonium]
The report includes 31 papers describing projects of the division. Of interest are the studies of plutonium and other transuranic elements in the Great Lakes and in the drainage basin of the Greater Miami River in Ohio. Emphasis has been placed upon attempts to understand the biogeochemical behavior of plutonium and other transuranic elements in the environment. A new program is described which examines the potential effects on aquatic ecosystems of pollutants related to nonnuclear energy conversion. Experiments designed to determine the hydrodynamic properties of waterborne particulates are included. A listing of publications by the staff of the section is given.

Effects of remelting and heat treatment on 2-1/4 Cr-1Mo steel elevated temperature tensile properties
Vacuum are remelting (VAR) and electroslag remelting (ESR) processes for steam generator tubesheet forgings and tubing are to be used at the CRBR. It was found that there is essentially no significant effect on the uniaxial tensile properties of 2 1/4 Cr-1Mo steel by VAR or ESR. A summary is presented of results of a study of heat treatment combined with post weld heat treatment. It was found that regardless of the primary heat treatment, the post weld heat treatment plus in-service conditions will reduce the yield strength at elevated temperature below the Code Case expected minimum curve.
