Amplified-response-spectrum analysis of sodium-water reaction pressure waves. [LMFBR] (open access)

Amplified-response-spectrum analysis of sodium-water reaction pressure waves. [LMFBR]

This report deals with a frequency spectrum evaluation of the SWAAM I predicted double rupture disc assembly operation pressure wave generated in the LLTR Series II A-2 test. It also evaluates the same wave predicted by the TRANSWRAP II code and the pressure wave actually measured upstream of the rupture disc assembly by the test instrumentation in Test A-2. The SWAAM I and TRANSWRAP II codes currently use the same analytical model to characterize the rupture disc until the disc strikes the knife edges. Thereafter, the SWAAM I code relies on analytical techniques to characterize the phenomena, whereas the TRANSWRAP II code uses empirical parameters based on A-2 test data to represent the disc behavior. Any differences in the predicted dynamic pipe loads caused by double rupture disc assembly operation, using the forcing functions predicted by the codes can, therefore, be traced to this difference.

Data acquisition system for the HHIRF spin spectrometer (open access)

Data acquisition system for the HHIRF spin spectrometer

The Spin Spectrometer at the Holifield Heavy Ion Research Facility (HHIRF) is a multidetector ..gamma..-ray spectrometer consisting of 72 separate NaI detector elements closely packed in a 4..pi.. geometry. The basic apparatus was constructed at Washington University and has been installed and implemented at the HHIRF at Oak Ridge National Laboratory. The spectrometer was designed especially for the investigation of the mechanisms of heavy-ion induced nuclear reactions and of the structure of nuclei with high angular momentum. The data acquisition system is described. (WHK)

Method of boronizing transition-metal surfaces (open access)

Method of boronizing transition-metal surfaces

A method is presented for preparing a boride layer on a transition metal substrate for use in corrosive environments or as a harden surface in machine applications. This method is particularly useful in treating current collectors for use within a high temperature and corrosive electrochemical cell environment. A melt of a alkali metal boride tetrafluoride salt including such as KF to lower its melting point is prepared including a dissolved boron containing material, for instance NiB, MnB/sub 2/, or CrB/sub 2/. A transition metal to be coated is immersed in the melt at a temperature of no more than 700/sup 0/C and a surface boride layer of that transition metal is formed within a period of about 24 hours on the substrate surface.

Fundamentals of interruption in vacuum. Eleventh progress report (open access)

Fundamentals of interruption in vacuum. Eleventh progress report

During the past three months effort has concentrated on formulating a method to predict the enhancement of electrode surface field and power input occasioned by the presence of a projection on the electrode surface, during the ion sheath development period which attends the scavenging a contact gap following current interruption in vacuum. In addition, experimental evidence has been obtained to support the theory, postulated earlier, of a turn-around interval for electrons left in the gap, which preceeds the rise of the transient recovery voltage.

Oil-shale-retorting and combustion system. [DOE patent application] (open access)

Oil-shale-retorting and combustion system. [DOE patent application]

The present invention is directed to the extraction of energy values from oil shale containing considerable concentrations of calcium carbonate in an efficient manner. The volatiles are separated from the oil shale in a retorting zone of a fluidized bed where the temperature and the concentration of oxygen are maintained at sufficiently low levels so that the volatiles are extracted from the oil shale with minimal combustion of the volatiles and with minimal calcination of the calcium carbonate. These gaseous volatiles and the calcium carbonate flow from the retorting zone into a freeboard combustion zone where the volatiles are burned in the presence of excess air. In this zone the calcination of the calcium carbonate occurs but at the expense of less Btu's than would be required by the calcination reaction in the event both the retorting and combustion steps took place simultaneously. The heat values in the products of combustion are satisfactorily recovered in a suitable heat exchange system.

Alternative fuels study: point-of-use component

The purpose of the concept paper is to outline a possible approach to conducting the point-of-use component of the Virginia Electric and Power Company (VEPCO) study of alternative fuels. Alternative measures for point-of-use application (specifically for the residential sector) would include conservation, solar space conditioning and water heating, and heat pumps. An outline is presented of analytical and field work that will provide information on parameters affecting users, the utility, and the market. Six interdependent activities discussed are: performance analysis, market research, utility impact analysis, comparative analysis, strategy planning, and implementation.
