Alan Icenhour

Alan Icenhour has been named associate laboratory director for nuclear science and engineering at Oak Ridge National Laboratory.

Icenhour will oversee ORNL’s contributions to isotope production, nuclear security and fission, and fusion research and technologies, as well as the U.S. Department of Energy’s Consortium for Advanced Simulation of Light Water Reactors. Icenhour has served as interim associate laboratory director since December.

Icenhour joined ORNL in 1990 and has worked in a variety of nuclear positions. Since 2008, he directed three divisions: the Global Nuclear Security Technology Division, the Fuel Cycle and Isotopes Division, and the Nuclear Security and Isotope Technology Division. [Read more…]

Test run signals emergence of the next generation in nuclear power reactor analysis tools

Scientists and engineers developing more accurate approaches to analyzing nuclear power reactors have successfully tested a new suite of computer codes that closely model “neutronics”—the behavior of neutrons in a reactor core.

Technical staff at Westinghouse Electric Company LLC, supported by the research team at the Consortium for Advanced Simulation of Light Water Reactors, or CASL, used the Virtual Environment for Reactor Applications core simulator (VERA-CS) to analyze its AP1000 advanced pressurized water reactor. The testing focused on modeling the startup conditions of the AP1000 plant design. [Read more…]
