Minimally refined biomass fuel. [carbohydrate-water-alcohol mixture]
A minimally refined fluid composition, suitable as a fuel mixture and derived from biomass material, is comprised of one or more water-soluble carbohydrates such as sucrose, one or more alcohols having less than four carbons, and water. The carbohydrate provides the fuel source; water-solubilizes the carbohydrate; and the alcohol aids in the combustion of the carbohydrate and reduces the viscosity of the carbohydrate/water solution. Because less energy is required to obtain the carbohydrate from the raw biomass than alcohol, an overall energy savings is realized compared to fuels employing alcohol as the primary fuel.

Analysis of the obstacles to financing geothermal hydrothermal commercialization projects and the government programs designed to remove them
The risks associated with geothermal hydrothermal commercialization are broken down into five categories: resource risk; technological risk; regulatory risk; investment parity risks; and institutional risk aversion. The impact of each risk upon geothermal financing is assessed. The federal government's programs to provide financial incentives for geothermal development are presented as follows: tax incentives; indirect financial incentives programs; direct grant/cost-sharing programs; and attempts at reducing regulatory risk through the enactment of legal and institutional reforms.

Guide for prioritizing power plant productivity improvement projects: modification and simplification of the DOE/MRI methodology
In recent years, the subject of public utility power plant productivity and reliability has received significant attention from both federal and state agencies and from within the utilities. One study was a FEA-sponsored program that had as its purpose the development of improved techniques for assessing cause of power plant unavailability. The results of this study have become widely known as the DOE/MRI methodology for calculating increased power plant equivalent availability resulting from instituting improvement projects. To further the development of the DOE/MRI methodology for assessing and quantifying the effect of improvement projects, the DOE initiated studies with two states to demonstrate the methodology in operating plants. These studies were focused on applying the methodology to specific power plants (fossil-fueled and nuclear) and on identifying any difficulties in using the method. In the course of these investigations, several problems were uncovered. Various recommendations were made for both eliminating the identified deficiencies in the methodology and for simplifying several of the calculations needed to evaluate proposed plant improvements. The information provided here describes four major modifications to the DOE/MRI methodology which eliminate previously uncovered deficiencies and simplify calculational methods.

Transistorized power switch and base drive circuit therefore
A high power switching circuit is disclosed which utilizes a four-terminal Darlington transistor block to improve switching speed, particularly in rapid turn-off. Two independent reverse drive currents are utilized during turn-off in order to expel the minority carriers of the Darlington pair at their own charge sweep-out rate. The reverse drive current may be provided by a current transformer, the secondary of which is tapped to the base terminal of the power stage of the Darlington block. In one application, the switching circuit is used in each power switching element in a chopper-inverter drive of an electric vehicle propulsion system.

Nuclear reactor fuel-assembly duct-tube-to-handling-socket attachment system. [LMFBR]
A reusable system is described for removably attaching the upper end of a nuclear reactor duct tube to the lower end of a nuclear reactor fuel assembly handling socket. A transition ring, fixed to the duct tube's upper end, has an interior-threaded section with a first locking hole segment. An adaptor ring, fixed to the handling socket's lower end has an outside-threaded section with a second locking hole segment. The inside and outside threaded sections match and can be joined so that the first and second locking hole segments can be aligned to form a locking hole. A locking ring, with a locking pin, slides over the adaptor ring so that the locking pin fits in the locking hole. A swage lock or a cantilever finger lock is formed from the locking cup collar to fit in a matching groove in the locking ring to prevent the locking ring's locking pin from backing out of the locking hole.

System for utilizing shale oil fines. [Patent application]
A system is provided for utilizing fines of carbonaceous materials such as particles or pieces of oil shale of about one-half inch or less diameter which are rejected for use in some conventional or prior surface retorting process, which obtains maximum utilization of the energy content of the fines and which produces a waste which is relatively inert and of a size to facilitate disposal. The system includes a cyclone retort which pyrolyzes the fines in the presence of heated gaseous combustion products, the cyclone retort having a first outlet through which vapors can exit that can be cooled to provide oil, and having a second outlet through which spent shale fines are removed. A burner connected to the spent shale outlet of the cyclone retort, burns the spent shale with air, to provide hot combustion products that are carried back to the cyclone retort to supply gaseous combustion products utilized therein. The burner heats the spent shale to a temperature which forms a molten slag, and the molten slag is removed from the burner into a quencher that suddenly cools the molten slag to form granules that are relatively inert and of a size that is convenient to handle …
