Analytical study of TATB preheating methods

Description: TATB (1,3,5 - triamino 2,4,6 - Trinitrobenzene) is a very stable explosive that is remarkably insensitive to severe impact and thermal environment. Experiments on its initiation and detonation characteristics have found it difficult to initiate under the energy transfer of thin flyer plates accelerated by electrically exploded metal foils. Figure 1 shows the propagation of a detonation front in such an experiment. Generally, the detonation waves are confined in the region directly in front of t… more

A Procedure for the Qualitative Interpretation of Fuel Centerline Thermocouple Response to Step-Power Decreases

Description: This report reviews the present calculational techniques that may be used to interpret the transient response of fuel centerline thermocouples to step decreases in rod power. A new technique developed herein involves plotting the natural logarithm of the normalized thermocouple data versus time, plotting various calculations in the same way, and observing the curvature of the resulting lines. Also described is the small computer code, MWRAM, which facilitates testing various models against tran… more

FLAT FLAME BURNER ANALYSES

Description: Velocity and temperature fields in the sintered material surrounding an embedded cooling coil in a Kaskan type flat flame burner are predicted. An approximate two-dimensional velocity field is obtained in closed form using a potential flow analogy. The velocity profile above the burner surface will be flat if the distance from the burner surface to the plane of the coil is sufficiently large that the coil wake is ameliorated. Quantitative results for this minimum distance are presented. Several… more

Mass Balance Results for Pricetown I Underground Coal Gasification

Description: A mass balance model was applied to the Pricetown I test data. This model gave the values of various parameters such as water influx, percent devolatilization, percent gasification, amount of coal affected, thermal efficiency, etc., for the various phases of the test. Both hourly and daily values of the test data were used. At certain times, there was air loss to the coal seam or air gain from the coal seam as related to the underground reactor. Mass balances are modified accordingly. Realistic… more

Description: The primary objective of this program is to develop and demonstrate an improved PWR fuel assembly design capable of batch average burnups of 45,000-50,000 MWd/mtU. To accomplish this, a number of technical areas must be investigated to verify acceptable extended-burnup fuel performance. This report is the first semi-annual progress report for the program, and it describes work performed during the July-December 1978 time period. Efforts during this period included the definition of a preliminar… more

Axisymmetric instability in a noncircular tokamak

Description: The stability of dee, inverse-dee and square cross section plasmas to axisymmetric modes has been investigated experimentally in Tokapole II, a tokamak with a four-null poloidal divertor. Experimental results are closely compared with predictions of two numerical stability codes - the PEST code (ideal MHD, linear stability) adapted to tokapole geometry and a code which follows the nonlinear evolution of shapes similar to tokapole equilibria.

Statistics of wind fluctuations over complex terrain

Description: This report deals with the properties of relative turbulence intensities, turbulent spectra and frequency distributions over uniform and complex terrain. As to intensities of turbulence, the report concentrates on properties of sigma/sub u//u/sub */, sigma/sub v//u/sub */, sigma/sub w//u/sub */, where the sigma's are the standard deviations of the longitudinal, transverse and vertical velocity components, respectively, and u/sub */ is the friction velocity. Given these ratios, relative turbulen… more

Energy-environmental impacts of five energy conservation measures in the Middle Atlantic and Pacific states

Description: Estimates of some energy and environmental impacts for five different energy-conservation measures (district heating, industrial cogeneration, retrofit, rate reform, and vehicle redesign) were prepared for two different regions (Middle Atlantic and Pacific) and two different time periods (1985 and 2000) based upon data presented in regional reference energy systems developed at BNL. Results of the analysis indicate that regional energy use can be reduced by <1 to 6%. Vehicle redesign produce… more

Evaluation of oxidation techniques for preparing bioassay and environmental samples for liquid scintillation counting

Description: In environmental and biological monitoring for carbon-14 and tritium, the presence of color and chemical quenching agents in the samples can degrade the efficiency of liquid scintillation counting. A series of experiments was performed to evaluate the usefulness, under routine conditions, of first oxidizing the samples to improve the counting by removing the color and quenching agents. The scintillation counter was calibrated for the effects of quenching agents on its counting efficiency. Oxidi… more

Strategic cost-benefit analysis of energy policies: detailed projections

Description: Current US energy policy includes many programs directed toward restructuring the energy system in order to decrease US dependence on foreign supplies and to increase our reliance on plentiful and environmentally benign energy forms. However, recent events have led to renewed concern over the direction of current energy policy.

Resource recovery: research development and demonstration plan

Description: Implementation of resource recovery is being retarded by technological uncertainties and institutional impediments. Development and commercialization of new competitive technologies are not proceeding rapidly because a structured development program for the industry is lacking. The US Department of Energy (DOE) has recognized these problems, and as part of its overall program in energy recovery from urban waste, it is developing a near- and longer-term research, development, and demonstration (… more

Strategic cost-benefit analysis of energy policies: overview

Description: This study describes three possible energy strategies and analyzes each in terms of its economic, environmental, and national security benefits and costs. Each strategy is represented by a specific policy. In the first, no additional programs or policies are initiated beyond those currently in effect or announced. The second is directed toward reducing the growth in energy demand, i.e., energy conservation. The third promotes increased domestic supply through accelerated development of syntheti… more
