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.

The FALCON reactor-pumped laser program is investigating concepts for high power laser systems pumped directly by fission energy from a nuclear reactor. The direct pumping of laser media with fission energy offers the potential system advantages of scaling to very high laser powers with long run times, extremely compact and low-mass energy storage, and relatively simple gain generator design. Reactor pumping has been studied in the ACRR and SPR research reactor facilities at Sandia National Laboratories. Based on these experiments and extensive system analysis, large reactor-pumped laser systems have been evaluated for extraction efficiency, beam quality, and practicality (considering auxiliary power needs, radiation damage to optical components, rejection of waste heat, and expected imperfections in excitation structures). It appears that high-power reactor-pumped lasers can be developed in the near term to provide important capabilities for the exploration and utilization of space.
