Recent advances in radiation transport simulation tools enable an increased fidelity and accuracy in modeling complex geometries. Future simulations for design and analysis will increasingly be based directly on 3-D CAD geometries. The Direct Accelerated Geometry Monte Carlo (DAGMC) toolkit has been developed for integration with various Monte Carlo physics packages (including MCNP5, Tripoli4, and GEANT4), combining advanced geometry capability with best-available physics. The DAG-MCNP5 combination has been used extensively for problems in fusion neutronics and irradiation experiment design with growing application to critical systems. In addition to extending the complexity of the geometry that can be simulated, another advantage of this approach is the common domain representation that it provides for coupled analysis. Benefits of this approach have been realized in hi-fidelity analysis of complex geometries, unique analysis of high-order geometries, and modeling of deformed structures. In addition to discussing the existing capabilities, this seminar will include some ideas of future advances including unstructured, conformal mesh tallies and hybrid methods.
About the Speaker
Paul Wilson joined the University of Wisconsin-Madison’s Engineering Physics department as an assistant professor in August 2001 as part of the Energy Systems and Policy Hiring Initiative. His research interests bring together technical and policy issues: analysis methods of isotopic inventories in nuclear systems and the implications on nuclear non-proliferation policy, and the development of next generation nuclear power systems to fulfill a role in future energy policy and needs. He began his graduate schooling in nuclear engineering at the University of Wisconsin-Madison. After three years, he moved to Karlsruhe, Germany, where he studied in the Institute for Neutron Physics and Reactor Engineering, earning his Dr.-Ing. degree in Mechanical Engineering in 1998. Returning to Madison, Paul completed his Ph.D. in Nuclear Engineering in 1999. Paul was the founding President of the North American Young Generation in Nuclear [NA-YGN], an organization created to provide unique opportunities to young professionals in all fields of nuclear science & technology. Paul has been active in the American Nuclear Society since 1994, and represented the ANS and NA-YGN at the international climate change negotiations in Buenos Aires, Argentina (1998), and Bonn, Germany (1999).
