Alan Icenhour has been named deputy for operations at the U.S. Department of Energy’s Oak Ridge National Laboratory. He will succeed Jeff Smith, who is retiring this spring after serving in the role since UT-Battelle began operating the lab in 2000, a press release said.

Icenhour joined ORNL in 1990 as an engineer, and he served most recently as associate laboratory director for the Isotope Science and Engineering Directorate. He led the Nuclear Science and Engineering Directorate from 2014 until the isotopes directorate was formed in October 2020. Icenhour has held a variety of other leadership positions as well as an assignment as senior technical adviser to the National Nuclear Security Administration, the press release said.

“Alan is a disciplined, thoughtful leader with broad experience at ORNL and proven success in a variety of roles,” ORNL Director Thomas Zacharia said in the press release said. “His ability to evaluate complex problems, find creative solutions, and build highly productive relationships will ensure the operational excellence necessary to support world-leading research and development.”
