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.

Recent inertial fusion experiments on the direct drive targets have attained the high neutron yield 1013 and the high density compression 600 times liquid density respectively. The electron degeneracy of core plasma was also observed. For the indirect drive target experiments, the radiation confinement was measured to keep the illumination uniformity. The ablation pressure of 100M bar is generated by soft X-ray radiation of 3 × 1014 W/cm2 over 1 nsec which produces the implosion velocity of 3 × 107 cm/sec. The development of the reactor driver of a few M joule is the most important issue for the inertial fusion energy program.
