Fundamental studies of coal liquefaction. Quarterly report No. 8, July 1, 1993--October 1, 1993

In the last report the effects of water, tetralin, and argon were discussed as media during the heating of Illinois No. 6 coal. In studies in which the temperature was ramped from ambient to 460{degrees}C at 30{degrees}C/min particles were observed to shrink in the case of both water and tetralin, and first swell and then collapse back to particles with their starting shapes in the case of argon. The result with tetralin was expected, but that for water was not. Similarly, the results in argon were not in accord with some models of coal pyrolysis which suggest that coals fully liquefy when heated (Solomon, et al.). The work described here includes discussion of additional work with Illinois No. 6 coal with argon and water, and new work with n-undecane as medium.

Industrial grand challenges: A competitiveness strategy for the DOE national laboratories (open access)

Industrial grand challenges: A competitiveness strategy for the DOE national laboratories

The Cold War has been won; won in part by superior technology; superior technology such as that found in the DOE national laboratories. However, new challenges face the country, for it is clear that our historic notions of national security have changed to include economic security as well as defense. Economic security means that our industries are able to successfully compete in international markets in order to provide a high domestic standard of living. It is also recognized that US industries must achieve and maintain a leadership in technology and that the technology base of the DOE national laboratories must now be mobilized to support US industry. Once again the laboratories are called upon to support the country in a time of need. Because of this need we are seeing a significant change in mission for the Department of Energy national laboratories in their role as problem solvers for the nation. In particular, the Defense Programs (DP) national labs (Lawrence Livermore, Los Alamos, Sandia National Laboratories, and Martin Marietta Energy Systems Y-12) are moving from dosed institutions to open centers with significant resources ready to support US industry more vigorously than ever before. The DP laboratories are enthusiastic about their …

Performance of a 14-MeV neutron generator as an in situ calibration source for TFTR (open access)

Performance of a 14-MeV neutron generator as an in situ calibration source for TFTR

TFTR will soon enter its D-T phase with the introduction of tritium. This will result in the production of neutrons having 14-MeV energy which is significantly greater than the 2.5-MeV neutrons encountered during D-D operation. In preparation for the D-T phase, a calibration of the four neutron detection systems was performed using a 14-MeV neutron generator producing 10{sup 8} n/sec. To account for the spatial extent of the toroidally shaped plasma and for neutrons scattered from surrounding structures, detector responses were determined with the source positioned at many locations inside the vacuum vessel. Before the generator could be used as a calibration source, a characterization of its total yield and angular emission properties was obtained. The total yield was determined by aluminum activation methods to within {plus_minus}6%, while the angular emission was found to be anisotropic in the forward and reverse cones along the generator axis. After the characterization was performed, the generator was mounted on a moveable track inside the vacuum vessel, where it could be remotely moved across the view of each detector. This paper presents details of the methods and results of the source characterization, together with initial results of the in-vessel D-T neutron calibration.

Use of bioassays in assessing health hazards from complex mixtures: A RASH analysis (open access)

Use of bioassays in assessing health hazards from complex mixtures: A RASH analysis

The Finney harmonic mean model for joint toxicity of ingredients in mixtures can be used to estimate the toxicity of the neat compound if one component can be substituted in potency-adjusted-doses for each of the other components. Chemical analysis data and relative potency values (computed according to the Rapid Screening of Hazard (RASH) method) were used to compare the toxicities as predicted from ingredients of cigarette smoke, PAHs in diesel exhaust, asphalt, coal tar, pitch, and creosote with the measured toxicities of the neat mixtures. Accuracy for cigarette smoke condensate, coal tar, pitch, and creosote were within a factor of three; asphalt within a factor of 18; but the PAC content of diesel particulate was inadequate to accurately describe the toxicity of diesel emissions.
