Reactor Physics and Fuel Cycle Analysis


Reactor physics and fuel cycle analysis is a core competency of the Nuclear Engineering (NE) Division. The Division has played a major role in the design and analysis of advanced reactors, particularly liquid-metal-cooled reactors. NE researchers have concentrated on developing computer codes for the assessment of reactor performance and safety characteristics, validating computer models by using experimental information obtained at critical facilities and power reactors, and applying these models in analyses that support core design and fuel cycle optimization.

Since the termination of the U.S. liquid-metal reactor development program in 1994, the Division has placed increased emphasis on such current national priorities as optimizing the operation of existing nuclear power plants, improving capabilities for confirming reactor safety, addressing problems associated with the safe disposition of spent fuels and excess weapons materials, and transmutation of transuranics and long-lived fission products. At the same time, the Division continues to enhance its core capabilities in advanced reactor design and is well positioned to play a leading role in developing advanced nuclear energy systems.

  • Heat flow around a seven-pin fuel rod assemblyComing Back To Nuclear Energy — High-performance computing will lead to safer, cheaper nuclear reactors that generate electricity more efficiently, "Argonne Now", Spring 2008
    When it was founded in 1946, Argonne was charged with developing the technology to enable peacetime uses of nuclear energy. Now, more than 60 years later, Argonne again stands at the forefront of nuclear research as it brings its new high-performance computing facilities to bear on reactor design, enabling safer, cheaper and more efficient generation of electricity. A feature article in the Spring issue of "Argonne Now" explains how Argonne's newly acquired access to petascale-capable hardware, combined with three decades of accumulated scientific expertise, will revolutionize how scientists and engineers model nuclear reactors. NE's director Hussein Khalil and physicist Won-Sik Yang (Nuclear Systems Analysis Dept., Simulation & Methods Section) were interviewed for this article.
