Semiclassical methods in chemical dynamics
A general semiclassical (multidimensional WKB-type) approximation to quantum mechanics is reviewed. The principal feature of the approach is that it is able to incorporate the exact classical mechanics of the system and also the quantum principle of superposition. Applications to inelastic and reactive scattering, and to statistical mechanics and reaction rates are discussed. 13 refs.

Transient plasma estimation: a noise cancelling/identification approach
The application of a noise cancelling technique to extract energy storage information from sensors occurring during fusion reactor experiments on the Tandem Mirror Experiment-Upgrade (TMX-U) at the Lawrence Livermore National Laboratory (LLNL) is examined. We show how this technique can be used to decrease the uncertainty in the corresponding sensor measurements used for diagnostics in both real-time and post-experimental environments. We analyze the performance of algorithm on the sensor data and discuss the various tradeoffs. The algorithm suggested is designed using SIG, an interactive signal processing package developed at LLNL.

Implicit Plasma Simulation
Implicit time integration methods have been used extensively in numerical modelling of slowly varying phenomena in systems that also support rapid variation. Examples include diffusion, hydrodynamics and reaction kinetics. This article discussed implementation of implicit time integration in plasma codes of the ''particle-in-cell'' family, and the benefits to be gained.

Plant monitoring techniques and second generation designs
Chemical and instrumental monitoring techniques suitable for geothermal use are described in a manner to relate them to plant operational problems and downtime avoidance. The use of these techniques permits the detection of scaling, the onset of scaling, corrosion loss, current corrosion rates and incipient heat exchanger failure. Conceptual advances are noted which simplify the research techniques to approaches that should be usable even in some low-capital well-head type power plants. 10 refs., 8 figs.

Direct utilization of geothermal energy for Haakon School District, South Dakota. Final report, January 1977-March 1985
This report is a summary of a project which demonstrates the successful use of geothermal energy for service water and space heating of school, business and commercial buildings in the city of Philip, South Dakota. The project included a new well into the Madison limestone formation, a pipe line to the school and through the central business district to a treatment plant, the treatment plant and settling ponds, conversion of the existing space heating systems of the buildings to equipment suitable for heating with the geothermal energy and monitoring the system to determine operating characteristics and efficiency. The treated water is discharged into the north fork of the Bad River for use by down stream irrigators. 24 figs., 19 tabs.

Special topics reports for the reference tandem mirror fusion breeder. Volume 5. Neutronic issues and optimization
More rigorous nuclear analysis, including the treatment of resonance self-shielding effects coupled with an optimization procedure, has resulted in improved performance of the Be/Li/Th blanket. Net U-233 breeding ratio has increased 36% (to 0.84) while at a U/Th ratio of 0.25 a/o energy multiplication has increased 12% (to 2.1) compared with earlier results.
