A numerical methodology to incorporate anisotropic elasticity into three-dimensional dislocation dynamics codes has been developed, employing theorems derived by Lothe (1967), Brown (1967), Indenbom and Orlov (1968) and Asaro and Barnett (1976). The formalism is based on the stress field solution for a straight dislocation segment of arbitrqq orientation in 3-dimensional space. The general solution is given in a complicated closed integral form. To reduce the computation complexity, look-up tables are used to avoid heavy computations for the evaluation of the angular stress factor ({Sigma}{sub ij}) and its first derivative term ({Sigma}{sub ij}). The computation methodology and error analysis are discussed in comparison with known closed form solutions for isotropic elasticity. For the case of Mo single crystals, it is shown that the difference between anisotropic and isotropic elastic stress fields can be as high as 15% close to the dislocation line, and decreases significantly far away from it. This suggests that short-range interactions should be evaluated based on anisotropic elasticity, while long-range interaction can be approximated using isotropic elasticity.

A part of the Nuclear Energy Research Initiative (NERI) is the development of the Small Transportable Autonomous Reactor (STAR) for deployment in countries that do not have a nuclear industry. STARs would have an output of from 100 to 150 MW electric, would be fueled in the country of manufacture, and after 15 to 20 years of operation the reactor core would be returned to the country of manufacture for refueling. A candidate STAR design can be found in (Greenspan, 2000). This paper describes the design of the control and monitoring system that might be used. There are two unique features to this system. One is that the monitored information will be transmitted to a remote site for two purposes, safeguards, and allowing experts a great distance away direct access to view the reactor's operating parameters. The second feature is safeguards sensors will be designed into the system and there will monitoring of the safeguards aspects of the system for tampering. Any safeguards anomalies will be sent to the remote site as alarms. Encrypted satellite communications will be used to transmit the data. These features allow the STAR to be operated by a small staff and will reduce the costs …

The objective of this project is to facilitate the ligand development process for f-block metal ions, i.e., the actinides and lanthanides, by developing an accurate set of criteria for the design of ligand architectures. To achieve this objective we first combine theory and experiment to understand the nature of fundamental interactions in selected metal-ligand systems. These design criteria provide a basis for proposing improved Ligand architectures. We then incorporate this understanding within the framework of a molecular mechanics force field to allow the rapid calculation of geometries and energies for ligands and their metal complexes. This computational model provides a method for quickly screening proposed architectures to identify the best candidates for subsequent synthesis and testing.

The UNSAT-H model was developed at Pacific Northwest National Laboratory (PNNL) to assess the water dynamics of arid sites and, in particular, estimate recharge fluxes for scenarios pertinent to waste disposal facilities. To achieve the above goals for assessing water dynamics and estimating recharge rates, the UNSAT-H addresses soil water infiltration, redistribution, evaporation, plant transpiration, deep drainage, and soil heat flow. The UNSAT-H model simulates liquid water flow using the Richards equation, water vapor diffusion using Fick's law, and sensible heat flow using the Fourier equation. This report documents UNSAT-H Version 3.0. The report includes the bases for the conceptual model and its numerical implementation, benchmark test cases, example simulations involving layered soils and plants, and the code manual. Version 3.0 is an enhanced-capability update of UNSAT-H Version 2.0 (Fayer Jones 1990). New features include hysteresis, an iterative solution of head and temperature, an energy balance check, the modified Picard solution technique, additional hydraulic functions, multiple year simulation capability, and general enhancements. This report includes eight example problems. The first four are verification tests of UNSAT-H capabilities. The second four example problems are demonstrations of real-world situations.
