Recommendations to ERDA of four solar heating and cooling demonstration projects are presented. Recommendations include (1) the Westchester Work Center Building owned by Bell Telephone Company of Pennsylvania, (2) the Scottsdale County Courts Building in Scottsdale, Arizona, (3) Howard Johnson's Inc. Hotel in North Miami, Florida, and (4) a combination warehouse, manufacturing facility offered by Mr. John I. Ladd of Ladd Brothers, Pueblo, Colorado. A conceptual diagram and a fact sheet is included for each proposed demonstration site. The combined estimated cost for the four projects is $334,586. (WHK)

Research efforts on the southeast continental shelf currently describe the manner in which fluctuations in Gulf Stream motion influence biological and chemical processes. Current meter arrays are maintained in the Georgia Bight and in Onslow Bay to describe general circulation patterns and to identify forcing functions. biological studies describe processes affecting temporal and spatial variations on the shelf and have attempted to track the biological history of intruded Gulf Stream water masses. Chemical studies examine the influence of both physical and biological variables on the distribution and fate of trace elements. The current state of knowledge is reviewed, the hypotheses developed and are described, a rationale for testing these hypotheses is given. 1 figure, 1 table.

It was the purpose of this project to broadly survey pathways of radionuclides in the coal fuel cycle, identifying critical questions and providing direction for subsequent, definitive studies of radionuclides in coal and the technological enhancement of concentrations of naturally occurring radionuclides through use of this coal. Western coal was selected for study because of its prominence in the National Energy Plan. Specific objectives were to: investigate the fate of radionuclides in the coal fuel cycle and, where possible, delineate the scope of the potential environmental and human health problem associated with radionuclides in coal; compile and evaluate data for uranium-238, uranium-234, lead-210, polonium-210, and thorium-230 in coal; study the release, fate, and accumulation of radionuclides from a power plant burning Western coal; and assess the possible need for additional control technology or standards. Results indicate that concentration of radionuclides in coal from Western mines varies widely, both within and between mines similar to other minor and trace constituents. The concentration of radionuclides in Western coal being mined today is roughly comparable to that of Eastern coal and is slightly below the average for all U.S. coal. A radionuclide balance for a power plant indicated that over 80% of uranium-234, …

The structure and features of selected certification programs were evaluated, their operational characteristics determined, and primary program problems and successes identified. An initial review of 50 certification programs in the Federal, state, and private sectors was performed, followed by a detailed review of 8 of the programs (EPA New Product noise; EPA Automobile Emissions, AHAM Room Air Conditioners; ARI Unitary Air Conditioners/Heat Pump; NHTSA Automobile Tire Safety; California Applicance Standards; Underwriters Laboratories Product Safety; and Ford's Quality-Assurance Program for Suppliers). Flow charts are presented to illustrate each program's structure and major characteristics. Matrices are developed to list the operating and control features of each program. Analyses of the 8 selected programs were performed to the degree necessary to develop and propose 5 potential approaches to an appliance certification/enforcement program (minimal intervention, strong certification control, strong enforcement audit, balanced certification and enforcement and strong enforcement remedies and deterrents). The approaches are documented in Section 3. The evaluation framework is described in Section 4, while a review of final test procedures and related public testimony are given in Section 5. (MCW)

Phase I of the Kilowatt Isotope Power System Program required a 1000 endurance test on the Ground Demonstration System (GDS). This report covers the teardown and inspection of the GDS after completion of over 1000 accumulated hr. After 1124.1 hours of operation, the GDS was torn down and inspected. The longest continuous run was 573.9 hr. With one exception, all shutdowns were intentional. The unintentional shutdown was not related to system operation, terminating a 447.8 hr run. The unit was restarted and the 573.9 hr run was completed. The minimum time component in the GDS, the NaK filled thermal sensor, accumulated 1043.1 operating hr. In general, the hardware was in excellent condition. Cases where discrepancies were noted are listed.

The number of beams required for optimum power transfer from a given power source to the surface of a pellet is derived. The result is valid for linear optical systems, hence, for pellet fusion by laser or high energy ion beams. The optimum number of beams turns out to be inconceivably large for any practical system. Practical pellet fusion by lasers or high energy heavy ion beams must thus compromise physical principles in favor of reduced cost and optical complexity.
