      Five companies, five bases: The Army’s Janus Program takes shape

      Between the Nuclear Lifecycle Innovation Campuses and Nuclear Energy Launch Pad programs, August has already been a busy month for federal partnerships with the nuclear industry.

      That trend continues: On Wednesday, the Department of the Army announced that it has selected five nuclear reactor developers—Antares Nuclear, BWXT Advanced Technologies, General Atomics Electromagnetic Systems, Radiant Industries, and Westinghouse Government Services—each paired with a different military installation, for its Janus Program.

      This week, the nuclear community descended on Dallas, Texas, for the second annual Nuclear Energy Conference and Expo, the premier industry-focused nuclear conference cohosted by the American Nuclear Society and the Nuclear Energy Institute. Among the plenary panelists was Jeff Waksman, principal deputy assistant secretary of the Army for installations, energy, and environment. Waksman has been closely involved in the development of the Janus Program, and the morning before the program’s new selections were unveiled, he provided insights on its ultimate goals at NECX 2026.

A Reactor Physicist’s Explanation of Chernobyl

April 26, 2022|12:00–1:30PM (1:00–2:30PM EDT)

MembersANS Members Only


ANS Members, please log in to watch this webinar.


Christopher Perfetti, assistant professor at the University of New Mexico, will analyze the Chernobyl accident from the viewpoint of a reactor physicist. He will explore the physical mechanisms that led to Chernobyl's runaway chain reaction and will explain why they are not possible in modern reactors. In addition, he will:

  • Explore fact vs. fiction for some tales surrounding Chernobyl
  • Discuss some interesting Chernobyl trivia
  • Look at recent photos from the actual Chernobyl site

This presentation will provide a valuable understanding of reactor physics, and will also provide enough interesting information about Chernobyl to appeal to seasoned reactor physicists.

Presenter

  • Christopher Perfetti, Assistant Professor, Nuclear Engineering Department, University of New Mexico

Moderator

  • Florent Heidet, Manager of the Advanced Nuclear Energy System (ANES) Group, Argonne National Laboratory Nuclear Science and Engineering (NSE) Division
