The 40th AAAS Gordon Conference on nuclear chemistry (open access)

The 40th AAAS Gordon Conference on nuclear chemistry

I am pleased to speak at the Fortieth Gordon Conference on Nuclear Chemistry. I served as Chairman of the first Gordon Conference on Nuclear Chemistry held June 23--27, 1952, at New Hampton, New Hampshire. In my remarks, during which I shall quote from my journal, I shall describe some of the background leading up to the first Gordon Conference on Nuclear Chemistry and my attendance at the first seven Gordon Conferences during the period 1952 through 1958. I shall also quote my description of my appearance as the featured speaker at the Silver Anniversary of the Gordon Research Conferences on December 27, 1956 held at the Commodore Hotel in New York City. I shall begin with reference to my participation in the predecessor to the Gordon Conferences, the Gibson Island Research Conferences 45 years ago, on Thursday, June 20, 1946, as a speaker. This was 15 years after the start of these conferences in 1931. Neil Gordon played a leading role in these conferences, which were named (in 1948) in his honor -- the Gordon Research Conferences -- soon after they were moved to Colby Junior College, New London, New Hampshire in 1947. W. George Parks became Director in 1947, …

Analysis of well test data---Application of probabilistic models to infer hydraulic properties of fractures. [Contains list of standardized terminology or nomenclatue used in statistical models]

Statistical and probabilistic methods for estimating the probability that a fracture is nonconductive (or equivalently, the conductive-fracture frequency) and the distribution of the transmissivities of conductive fractures from transmissivity measurements made in single-hole injection (well) tests were developed. These methods were applied to a database consisting of over 1,000 measurements made in nearly 25 km of borehole at five sites in Sweden. The depths of the measurements ranged from near the surface to over 600-m deep, and packer spacings of 20- and 25-m were used. A probabilistic model that describes the distribution of a series of transmissivity measurements was derived. When the parameters of this model were estimated using maximum likelihood estimators, the resulting estimated distributions generally fit the cumulative histograms of the transmissivity measurements very well. Further, estimates of the mean transmissivity of conductive fractures based on the maximum likelihood estimates of the model's parameters were reasonable, both in magnitude and in trend, with respect to depth. The estimates of the conductive fracture probability were generated in the range of 0.5--5.0 percent, with the higher values at shallow depths and with increasingly smaller values as depth increased. An estimation procedure based on the probabilistic model and the maximum likelihood …

Design of a high activity and selectivity alcohol catalyst (open access)

Design of a high activity and selectivity alcohol catalyst

As specified in our original DOE grant proposal, the objective of this research is to design a new alumina-supported bimetallic catalyst for the selective hydrogenation of carbon monoxide to produce methanol and higher alcohols. A key feature of our research program is our intention to rationally design this catalyst based upon fundamental information about the structure, composition and reactivity of preliminary catalysts synthesized throughout the course of this work. During our first year, we have put in place many of the tools needed to synthesize and characterize our catalyst samples. Experimentation has focused on both the synthesis of catalysts designed for high oxygenate activity and the suppression of the secondary dehydration of methanol to dimethyl ether on both native gamma-alumina and a bimetallic catalyst supported on gamma-alumina. 2 refs., 1 tab.

Modernization of Ohio's coal reserves, Phase 1 (open access)

Modernization of Ohio's coal reserves, Phase 1

The objectives of this project were to determine state-level totals of the estimated economic resource, minable reserve base, and recoverable coal in Ohio, allocated to specified ranges of sulfur and heat content. In addition, resources and reserves were to be categorized by mining methods (surface and underground). Land use and environmental restrictions, needed to determine remaining minable reserves, were to be delineated and percentages of restricted coal calculated. In context of a Phase 1, one-year project, the objectives of this project were to update Ohio's coal reserves and resources for as many counties as time allowed, and to deplete production tonnages to January 1, 1991, on the remaining coal-producing counties. For the depleted counties, only estimated economic resources were required or possible with the data available. 24 refs., 9 figs., 3 tabs.

Radioactive effluents in Savannah River (open access)

Radioactive effluents in Savannah River

During 1990, low-level radiometric studies of the Savannah River continued to distinguish between effluent contributions from Plant Vogtle and the Savannah River Site. Measurements of these radioactive effluents are of mutual interest to both institutions, as they can address disturbing trends before they become health and legal concerns. The Environmental Technology Section (ETS) has conducted radiometric studies of Plant Vogtle since late 1986, prior to its startup. The plant has two 1100 MWe pressurized water reactors developed by Westinghouse. Unit 1 started commercial operations in June 1987, and Unit 2 began in May 1989. During powered operations, ETS has routinely detected neutron-activated isotopes in controlled releases but all activities have been several orders of magnitude below the DOE guide values. In 1990, processing improvements for Vogtle effluents have yielded even lower activities in the river. The Vogtle release data and the ETS measurements have tracked well over the past four years.

Systematic effects in CALOR simulation code to model experimental configurations

CALOR89 code system is being used to simulate test beam results and the design parameters of several calorimeter configurations. It has been bench-marked against the ZEUS, D{theta} and HELIOS data. This study identifies the systematic effects in CALOR simulation to model the experimental configurations. Five major systematic effects are identified. These are the choice of high energy nuclear collision model, material composition, scintillator saturation, shower integration time, and the shower containment. Quantitative estimates of these systematic effects are presented. 23 refs., 6 figs., 7 tabs.

Vent Stack Liquid N2 RTD Temperature Sensor (open access)

Vent Stack Liquid N2 RTD Temperature Sensor

This engineering note documents the installation of two temperature sensing RTD's in the BC's. Previously, the temperature sensing device used in all three cryostats consisted of a FNAL designed liquid sensing probe (see EN-168, and drawing ME-273505). This device was necessary because of the concern that overfilling LN2 into the main vent line during cooldown could create an undesirable back pressure on the relief valves or rupture disks. This could possibly hinder the relieving of argon gas at the required flow rate in a safety situation. The probe was installed on the CC, and has been operating perfectly, therefore, this probe will not be changed. Figure 1 shows the location of TS232E, the CC liquid sensing probe. Note that the probe is located downstream of the condenser outlet valve (PV210N), therefore, it effectively operates under atmospheric pressure. On the BC's, however, the probe was originally installed at a different location, upstream of the condenser outlet valve (PV110N or PV310N). This resulted in the probe effectively sensing the condenser pressure, which varied from approximately 30 psia to 60 psia during cooldown. The changing pressure meant that the corresponding temperature at which liquid appeared also changed. The probe then became inaccurate, especially …

Workshop on technology issues of superconducting Maglev transportation systems (open access)

Workshop on technology issues of superconducting Maglev transportation systems

There exists a critical need in the United States to improve its ground transportation system. One suggested system that offers many advantages over the current transportation infrastructure is Maglev. Maglev represents the latest evolution in very high and speed ground transportation, where vehicles are magnetically levitated, guided, and propelled over elevated guideways at speeds of 300 miles per hour. Maglev is not a new concept but is, however, receiving renewed interest. The objective of this workshop was to further promote these interest by bringing together a small group of specialists in Maglev technology to discuss Maglev research needs and to identify key research issues to the development of a successful Maglev system. The workshop was organized into four sessions based on the following technical areas: Materials, Testing, and Shielding; Magnet Design and Cryogenic Systems; Propulsion and Levitation Systems; and, System Control and Integration.
