Task 3 of Contract AT03-76SF78003 consists of the following programs: fuel rod chemistry and thermodynamics; fuel rod engineering; fuel irradiations testing and analysis; reference structural materials. The four parts are closely interrelated and in combination are aimed at providing a sound basis for the design and performance evaluation of LMFBR mixed oxide fuel rods.

A method for estimating the useful lifetime of a reservoir in porous rock where the injection and production wells intersect a fracture system is presented. Equations were derived for the pore-fluid and fracture-fluid temperatures averaged over large regions of the geothermal field. Problems such as incomplete areal sweep and interfingering of cool and hot fluids are ignored. Approximate equations relating average temperatures to the heat flowing from rock to fluid were developed, and their use is justified by comparing the results with solutions of the exact equations. The equations for the temperature decline can be solved quickly. In the model, fractures are characterized by three parameters: aperture w, permeability k/sub fr/, and spacings between fractures D. For certain values of these parameters, cool reinjected fluid in fractures may reach the production wells long before all the warm pore fluid has been tapped, shortening the useful lifetime of the field. The traditional (and important) problems of reservoir engineering, flow rate determination, drawdown, sweep patterns, etc. were ignored. Thus the results are most useful in providing a correction factor which can be applied to lifetime estimates obtained from a detailed simulation of a field assuming porous rock. That correction factor is plotted …

Research on the use of cements in radioactive waste isolation is reported. Other research is reported on the effects of thermal treatments of clays and shales on their cation exchange capacities and relative sorptive properties for cations. Development of instrumentation for measuring thermal properties of cements at atmospheric pressure was completed. A method was developed for measuring heat flow in shales and cement. Data on thermodynamic properties of cements and shales are included. Studies of shales, siltstones, and evaporites including scanning electron microscopy are in progress. (JRD)

Analytical and experimental methods are presented for evaluating the vibration characteristics of cylindrical shells such as the thermal liner of the Fast Flux Test Facility (FFTF) reactor vessel. The NASTRAN computer program is used to calculate the natural frequencies, mode shapes, and response to a harmonic loading of a thin, circular cylindrical shell situated inside a fluid-filled rigid circular cylinder. Solutions in a vacuum are verified with an exact solution method and the SAP IV computer code. Comparisons between analysis and experiment are made, and the accuracy and utility of the fluid-solid interaction package of NASTRAN is assessed.

The reliability of stainless steel type 304L canisters for the containment of solidified high-level radioactive wastes in the glass and calcine forms was studied. A reference system, drawn largely from information furnished by Battelle Northwest Laboratories and Atlantic Richfield Hanford Company is described. Operations include filling the canister with the appropriate waste form, interim storage at a reprocessing plant, shipment in water to a Retrievable Surface Storage Facility (RSSF), interim storage at the RSSF, and shipment to a final disposal facility.

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 …

The philosophic basis and proposed implementation of an energy outreach program were set forth in a proposal of December 5, 1975 and in a revised proposal and budget of March 22, 1976, submitted after consultation with ERDA officials. The objectives and scope of work for the initial ten-month period presently contracted, and for the balance of the proposed two-year program, are summarized in the ERDA document ''Project: Outreach Program for Energy Information Dissemination in Adjacent Areas of New York, New Jersey, and Connecticut''. A copy is included at the end of this report. The implementation plan set forth here specifies the nature and the time schedule of the work to be accomplished throughout the tem-month and the two-year periods. In order to disseminate information to target audiences, the institute will utilize various energy technology channels of communications, including, the Energy Information Center; NYIT Energy Hot Line; Metropolitan Regional Council Television Seminars; Referral Services; press releases; technical assisance teams; newspaper question-and-answer columns; traveling displays; contests; conferences; radio spots; volunteers; and Center for Energy Policy and Research Periodical. All energy topics are included, but priority in the short term will be given to energy management programs for small commercial/industrial plants; residential building …

This report has a two-fold objective: (1) to identify major energy-related environmental concerns, needs, and problem areas, and (2) to show the relationship of the planned FY 1978 research program of the ERDA Assistant Administrator of Environment and Safety (AES) to those environmental issues. The document is organized into sections addressing each major energy form. Each section identifies environmental issues of an energy form and indicates the level of planned FY 78 AES research addressing each issue, thus delineating the links between environmental research and the needs of energy research, development, and demonstration (RD and D).

The Energy Information Center was created to serve (1) the research and information dissemination purposes of the Center for Energy Policy and Reearch, and (2) the information outreach programs of the Energy Advisory Service established by the Center. The Center is primarily concerned with (a) energy conservation, (b) alternative energy sources, (c) energy usage, and (d) energy policy, and insofar as they relate to these matters, it is concerned secondarily with fossil energy, nuclear energy, and international energy developments. Accordingly, the Energy Information Center acquires materials in such fields as engineering, economics, and the political, social, and behavioral sciences. In addition to serving the research and information dissemination needs of the Center for Energy Policy and Research, the Energy Information Center also supports the Center's Energy Advisory Service outreach program in which information and technical assistance in the use of energy conserving techniques and equipment is made available to industrial and commercial organizations, public officials, homeowners, and the general public throughout the New York New Jersey, and Connecticut area.
