- ANALYSIS AND MODELING OF MATERIALS BEHAVIOR IN ENERGY SYSTEMS
- A modern, high-speed, digital computer is employed to simulate the physical behavior of materials used in advanced energy systems (fission and fusion). In the fission area, the thermal, mechanical, and irradiation response of fuel elements for the Reduced Enrichment Research and Test Reactor (RERTR) program are analyzed. Emphasis is placed on realistic models that accurately describe the physical situation. The DART code system is being developed in order to assess the behavior of dispersion fuels for the RERTR. In the fusion area, the thermal, mechanical, and irradiation performance of solid breeders (Li2O and other ternary oxides) are being modeled. The TIARA code has been developed, verified and validated to predict the tritium inventory in lithium ceramics under fusion reactor operation conditions. Other research activities include the analysis of specific phenomena (e.g. helium-induced swelling) in order to identify key process and/or physical parameters that affect material performance and the thermal and mechanical responses of fusion first-wall structures under novel cooling schemes is being modeled

- VALIDATION OF COMPUTATIONAL TOOLS FOR NUCLEAR REACTOR SYSTEMS
- Computational power continues to grow and with it the ability to model in ever increasing detail the various phenomena that occur within nuclear reactor systems. Confidence in the reliability of simulation tools comes, in part, from benchmark/validation efforts in which predictions made by simulations are compared with experimental data. Ongoing activities include validation of in-house and commercially available computational tools using data from international benchmark projects as well as separate-effect and integral experiments from various test facilities and nuclear reactor systems.

Argonne a top place to work for postdocs in 2013
For the third year in a row, the U.S. Department of Energy's (DOE) Argonne National Laboratory is one of the 10 best places to work as a postdoctoral researcher, according to The Scientist magazine's annual survey. Argonne ranked fifth, moving up from sixth place last year, earning specific praise for its benefits and attention to personal and family life. More...
