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 compatibility of structural materials with lead and lead-bismuth eutectic is a significant challenge in the development of fast neutron reactors with heavy-liquid-metal coolants. Liquid-metal corrosion negatively affects ferritic-martensitic steel EP823-Sh. The mechanism of liquid-metal corrosion of steels corresponds to physicochemical dissolution when the oxygen content in lead is less than the equilibrium value. The selective dissolution of steel components from the surface of the claddings is observed. When the oxygen concentration exceeds the equilibrium value, the corrosion products are the outer oxide layer of magnetite and the chromium spinel of nonstoichiometric composition such as Fe(Fe1-x,Crx)2O4, as well as the development of an internal oxidation zone along the grain boundaries, which also can be observed. The pure-lead heat transfer sublayer between the fuel and the cladding causes the dissolution and deposition of steel components on the inner surface of the cladding. To increase corrosion resistance, it is proposed to modify the surface using plasma and laser processing, as well as by applying protective coatings.
