      Decommissioning & Environmental Sciences

      The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

      AI and productivity growth

      Craig Piercy
      cpiercy@ans.org

      This month’s issue of Nuclear News focuses on supply and demand. The “supply” part of the story highlights nuclear’s continued success in providing electricity to the grid more than 90 percent of the time, while the “demand” part explores the seemingly insatiable appetite of hyperscale data centers for steady, carbon-free energy.

      Technically, we are in the second year of our AI epiphany, the collective realization that Big Tech’s energy demands are so large that they cannot be met without a historic build-out of new generation capacity. Yet the enormity of it all still seems hard to grasp.

      or the better part of two decades, U.S. electricity demand has been flat. Sure, we’ve seen annual fluctuations that correlate with weather patterns and the overall domestic economic performance, but the gigawatt-hours of electricity America consumed in 2021 are almost identical to our 2007 numbers.

Kenneth Petersen

ANS President 2023-2024

Kenneth Petersen is an executive consultant to the nuclear power industry, providing strategy, management, and technical consulting related to nuclear fuel and special nuclear material. Prior to his retirement in November 2021, Petersen was Exelon Generation Company’s (EGC’s) vice president for nuclear fuels. In this role, he provided governance and oversight for all aspects of the nuclear fuel cycle for Exelon’s fleet of 21 operational reactors and three retired reactors. He led Exelon’s fuel purchasing, nuclear core design and related safety analyses, and spent fuel management.

Petersen has nearly three decades of experience purchasing nuclear fuel, and during his 12 years as ECG’s vice president for nuclear fuels, he oversaw the company’s $1 billion annual budget for nuclear fuel procurement and managed a nuclear fuel contract portfolio valued at over $5 billion. His fuel supply responsibilities included the development of risk management metrics and strategic decisions related to fuel, inventory levels, and pricing mechanisms. In addition, he developed nuclear core design and safety analysis skills. He played a key role in the technical aspects of utilizing fuel in the reactors and was a major industry advocate for accident tolerant fuel designs, including coated fuel rods, high burnup, and high enrichment.

Petersen’s long history with spent fuel and special nuclear material includes his involvement with executing the U.S. Department of Energy’s (DOE’s) Standard Contract and, subsequently, EGC’s litigation and eventual settlement with the DOE. He also had governance and oversight over the installation of EGC-constructed independent spent fuel storage facilities. Petersen earned his bachelor’s and master’s degrees in nuclear engineering from the University of Wisconsin and began his career Commonwealth Edison upon graduation in 1988.
