Marketing of coal mining equipment. Evaluation of present techniques: suggestions to aid commercialization. Final report

Description: This report is an examination of the equipment preferences and decision-making methodology of the coal industry. The prime purpose is to indicate directions in which equipment research might proceed and also to indicate methods by which investment in new, more productive mining equipment could be encouraged. In addition to this, an investigation of the research and development decisions of major mining equipment manufacturers was conducted. The findings can best be condensed into three categori… more

Fluidized bed incineration process design for transuranic waste

Description: A fluidized bed incineration facility has been installed at the Rocky Flats Plant to develop and demonstrate a process for the combustion of transuranic waste. The unit's capacity is about 82 kg/hr of combustible solid waste, which is nine times higher than the rate for the operating pilot-scale unit. The facility utilizes nonaqueous, in situ neutralization of acid gases. These gases are generated during the combustion of halogen-containing materials. The low-temperature (550 /sup 0/C) ope… more

Discrete-event simulation of nuclear-waste transport in geologic sites subject to disruptive events. Final report

Description: This report outlines a methodology to study the effects of disruptive events on nuclear waste material in stable geologic sites. The methodology is based upon developing a discrete events model that can be simulated on the computer. This methodology allows a natural development of simulation models that use computer resources in an efficient manner. Accurate modeling in this area depends in large part upon accurate modeling of ion transport behavior in the storage media. Unfortunately, developm… more

Thermal conductivity of rocksalt and other geologic materials from the site of the proposed waste isolation pilot plant

Description: The measurements first reported by Acton on the thermal conductivity of samples taken from a borehole at the site of the proposed nuclear waste isolation pilot plant (WIPP) near Carlsbad, NM, have been extended to include additional samples and higher temperature measurements. Samples for measurements were taken from several depths of three wells, including the well AEC 8 from which Acton obtained his samples. These samples ranged from relatively pure rocksalt (NaCl) with small amounts of inter… more

Use of coaxial plasma guns to start up field-reversed-mirror reactors

Description: Application of a magnetized coaxial plasma gun for start-up of a field-reversed-mirror reactor is considered. The design is based on preliminary scaling laws and is compared to the design of the start-up gun used in the Beta II experiment.

Wave heating models for ion-cyclotron heating in EBT-S

Description: Wave heating of ELMO BUMPY TORUS-SCALE (EBT-S) in the ion-cyclotron range of frequencies will be strongly influenced by the geometry of the plasma. In particular, the short finite length of the mirror sections means that the electron bounce frequency is of comparable magnitude to the ion-cyclotron frequency. Consequently, the bouncing motion of trapped particles impacts the electron absorption of wave energy. Furthermore, the varying magnetic field strength along magnetic field lines influences… more

Seismic Safety Margins Research Program. Phase I. Interim definition of terms

Description: This report documents interim definitions of terms in the Seismic Safety Margins Research Program (SSMRP). Intent is to establish a common-based terminology integral to the probabilistic methods that predict more realistically the behavior of nuclear power plants during an earthquake. These definitions are a response to a request by the Nuclear Regulatory Commission Advisory Committee on Reactor Safeguards at its meeting held November 15-16, 1979.

Evaluation of selected chemical processes for production of low-cost silicon. Phase III. Twentieth quarterly progress report, July 1-September 30, 1980

Description: A number of problems have conspired to prevent full operation of the PDU during the report period. After a review of the situation, it was decided to cease the day-by-day attempts to achieve PDU operation, and to review the situation and make such longer-term repairs or modifications as appeared necessary for increasing the probability of success. As a result, a list of 12 modifications was made and the modifications initiated so that PDU operation can be initiated early in the next quarter. An… more

Ionization in liquids. Progress report, September 1, 1977-April 30, 1981

Description: Quasifree electrons simulate the behavior of unsolvated or dry electrons in aqueous media including the special case of biological systems. A model of direct radiosensitization was developed based on dry charge-carriers having an extended lifetime in the sheath of structured water that surrounds polar biomolecules. In this model, the pre-solvation lifetimes of dry electrons increased with an increase in the rotational times of solvent molecules. During the development of this model, an increasi… more
