Rapporteur report: MHD electric power plants

Five US papers from the Proceedings of the Seventh International Conference on MHD Electrical Power Generation at the Massachusetts Institute of Technology are summarized. Results of the initial parametric phase of the US effort on the study of potential early commercial MHD plants are reported and aspects of the smaller commercial prototype plant termed the Engineering Test Facility are discussed. The alternative of using a disk geometry generator rather than a linear generator in baseload MHD plants is examined. Closed-cycle as well as open-cycle MHD plants are considered

Nationale Anpassungsstrategien an das Fallrecht des Europäischen Gerichtshofes: Europäisierung durch Richterrecht und innenpolitische Veto-Positionen

Die Bedeutung des Europäischen Gerichtshofes (EuGH) als 'Motor der Integration' ist allgemein anerkannt. Welche Auswirkungen die Rechtsprechung des Gerichtshofes in den EU-Mitgliedstaaten hat, ist bisher weniger gut erforscht. Dieser Artikel analysiert die Umsetzung der Urteile Laval (C-341/05) und Rüffert (C-346/06) in Dänemark, Schweden und Deutschland. Wie können die unterschiedlichen Ergebnisse der nationalen Anpassungsprozesse erklärt werden? Um diese Frage zu beantworten, erweitert der Beitrag das Instrumentarium der Europäisierungsforschung um eine politökonomische Analyseperspektive. Die Untersuchung zeigt, dass die Urteile die Veto-Positionen in den innenpolitischen Arenen zuungunsten der Gewerkschaften verschoben haben. Die Option, gegen nationale Regulierungen und Praktiken rechtlich vorzugehen, stärkt die Position der Arbeitgeber. Daher lassen sich die unterschiedlichen Ergebnisse der Anpassungsprozesse auf variierende Präferenzen der Arbeitgeber bezüglich der Regulierung von Lohnkonkurrenz zurückführen

Engineering test facility design definition

The Engineering Test Facility (ETF) is the major focus of the Department of Energy (DOE) Magnetohydrodynamics (MHD) Program to facilitate commercialization and to demonstrate the commercial operability of MHD/steam electric power. The ETF will be a fully integrated commercial prototype MHD power plant with a nominal output of 200 MW sub e. Performance of this plant is expected to meet or surpass existing utility standards for fuel, maintenance, and operating costs; plant availability; load following; safety; and durability. It is expected to meet all applicable environmental regulations. The current design concept conforming to the general definition, the basis for its selection, and the process which will be followed in further defining and updating the conceptual design

A summary of the ECAS MHD power plant results

The performance and the cost of electricity (COE) for MHD systems utilizing coal or coal derived fuels are summarized along with a conceptual open cycle MHD plant design. The results show that open cycle coal fired recuperatively preheated MHD systems have potentially one of the highest coal-pile-to-bus bar efficiencies (48.3%) and also one of the lowest COE of the systems studied. Closed cycle, inert gas systems do not appear to have the potential of exceeding the efficiency of or competing with the COE of advanced steam plants

Incidental Archeological Resource Investigation At The Integrated Pipeline Project\u27s Cedar Creek Reservoir Pump Station Site And 41HE377 Henderson County, Texas

Archeologists from AmaTerra Environmental, Inc. (AmaTerra), working on behalf of the Tarrant Regional Water District (TWRD) and their environmental compliance subconsultant, Freese & Nichols, Inc., conducted an emergency investigation at the previously recorded Site 41HE377 at the Cedar Creek Reservoir Pump Station in Henderson County, Texas. The investigation was conducted after a private citizen reported finding a human jaw bone along the shoreline at 41HE377 and expressed concern that the pump station, which is currently under construction, may be impacting an unrecorded cemetery. Initially recorded in 2011, 41HE377 was documented as a thin surface scatter of prehistoric artifacts occupying the Cedar Creek reservoir’s shoreline at a proposed pump station site for TRWD’s Integrated Pipeline Project. The site was recommended as not eligible for the NRHP because it contained no intact deposits along the shoreline or farther inland. At the time of recording, archeologists speculated that the lithic debris along the shoreline appeared to be washing in from elsewhere in the lake through wave action. In April 2017, archeologists inspected the pump station construction site and Site 41HE377 area for any evidence of human remains or disturbed burials and met with the informant, Bobby Wright. AmaTerra found no evidence of burials or displaced human remains. Once at the site, Mr. Wright indicated that he thought the jawbone had washed up from the reservoir when he found it two years earlier, when water was lower than its current level. He was not able to show investigators the bone because he had reburied it and could not relocate it due to landscape modifications made during construction activities at the pump station site and higher water levels. Thus, archeologists were not able to confirm its presence or that the reported bone was indeed human. Based on the lack of any real evidence of human remains at the Cedar Creek Pump Station Site, AmaTerra recommends that continued construction at the pump station should proceed with no further cultural resource coordination required under the NHPA or the ACT. However, due to the continued potential for an unmarked cemetery somewhere under the lake, AmaTerra recommends TRWD staff conduct periodic surface inspection along the shoreline, particularly along its northeastern segment when water levels are low
