Acoustic emission from beryllium

Description: The acoustic emission from both powder and ingot source beryllium has been measured as a function of strain and prior heat treatment. Most measurements were made during tensile deformation, but a limited number of compression tests have also been performed. The acoustic emission observed was of the burst type, with little or no contribution from continuous type emission. The emission was characterized by the variation of burst rate and average energy per burst as a function of strain. The tensi… more

Description: This LTR contains the original results of the Railroad Locomotive Tractive Effort Test performed by Kaiser Engineers on July 29, 1965, using an existing 24-wheel 500-ton dolly and the existing shielded locomotive. The test was conducted to confirm calculations of the tractive effort required to move the LOFT dolly (MTA) through the four-rail high bay curve and the curve into the LOFT containment vessel.

Evaluation of the photochemical production of hydrogen from solar energy

Description: The potential for utilizing solar energy through photochemical storage were investigated. Both water and nitrosyl chloride systems are examined. A comprehensive review of the literature led to the conclusion that many major questions must be answered before photochemical energy storage becomes a viable alternate means of exploiting solar energy.

Mechanical refrigerator for deep well sonde electronics, Phase II. Final report

Description: The system is based on a vapor cycle refrigeration system with the usual compressor, evaporator and condenser. It is designed to operate between a condensing temperature of 275/sup 0/C and an evaporating temperature of 125/sup 0/C. Water vapor is the refrigerant. The compressor is an electric motor driven three-stage positive displacement machine. The design output of the refrigerator is 50 watts cooling. The work described covers the development of the compressor with associated component deve… more

Preliminary design for Ocean Thermal Energy Conversion (OTEC) Stationkeeping Subsystem (SKSS). Task IV. Development and testing recommendations

Description: The preliminary designs of Stationkeeping Subsystems (SKSS) for the OTEC Modular Experiment Plant are being prepared for a barge and spar platform. The SKSS selected by NOAA for the barge is a multiple anchor leg mooring with active tensioning (MAL), while that for the spar is a tension anchor leg (TAL) moor. The development and testing program required to provide design data and to validate performance predictions is described. Basic assumptions are made with regard to site characteristics, be… more

Core Power and Decay Time Limits for a Disabled LOFT ECCS

Description: An analysis was done to determine at what LOFT total core power (nuclear plus decay power) the ECCS could be inoperable. The criteria used for the analysis was that the maximum fuel clad temperature should not exceed 1650/sup 0/F given a loss of coolant. Calculations for natural convection cooling of the fuel by air with an inlet temperature of 580/sup 0/F determined that the limiting core power is 25 kW (discounted by 15 percent to 20 percent for potential uncertainties). Shutdown times are li… more

Evaluation of selected chemical processes for production of low-cost silocon. (Phases I and II. ) Final report, October 9, 1975--July 9, 1978. Silicon Material Task, Low-Cost Solar Array Project

Description: The zinc reduction of silicon tetrachloride in a fluidized bed of seed particles to yield a granular product was studied along with several modifications of the thermal decomposition or hydrogen reduction of silicon tetraiodide. Although all contenders were believed to be capable of meeting the quality requirements of the LSA Project, it was concluded that only the zinc reduction of the chloride could be made economically feasible at a cost below $10/kg silicon (1975 dollars). Accordingly, subs… more

Theory and simulation of laser plasma coupling

Description: The theory and simulation of these coupling processes are considered. Particular emphasis is given to their nonlinear evolution. First a brief introduction to computer simulation of plasmas using particle codes is given. Then the absorption of light via the generation of plasma waves is considered, followed by a discussion of stimulated scattering of intense light. Finally these calculations are compared with experimental results.

Efficiency improvements in pipeline transportation systems

Description: This report identifies potential energy-conservative pipeline innovations that are most energy- and cost-effective and formulates recommendations for the R, D, and D programs needed to exploit those opportunities. From a candidate field of over twenty classes of efficiency improvements, eight systems are recommended for pursuit. Most of these possess two highly important attributes: large potential energy savings and broad applicability outside the pipeline industry. The R, D, and D program for… more

LOFT CRDM vent orifices

Description: The failure of a vent line on the LOFT control rod drive mechanism (CRDM) would result in the quick blowdown of the top of the CRDM with high pressure in the lower region. This large pressure drop across the lead screw could possibly eject the control rod assembly (CRA) from the reactor core. The rod ejection accident has been analyzed for the LOFT core but in this case a common mode failure may cause the loss of all four vent lines. Therefore, orifices must be installed in each CRDM pressure c… more

Cadmium sulfide/copper sulfide heterojunction cell research. Technical progress report No. 2, January 1--March 31, 1978

Description: Poor adhesion of CdS films to zinc-plated copper foil substrates has been eliminated by depositing somewhat thinner films than earlier and by using the mat (as opposed to the smooth) side of the electroformed copper foil for deposition. Particle spatter effects have been reduced and cells of 4 cm/sup 2/ area have been produced with average efficiency of 5.4%. Use of Zn--plated Cu, Mo, Zn--plated Mo and glass substrates appears to influence the etching behavior of CdS films in dilute chromic aci… more
