Uses helium gas as coolant instead of water. Operates at higher temperature for greater thermal efficiency.

Powers ~40,650 average US homes. A standard large nuclear plant produces ~1,000 MWe.

Inert gas that cannot become radioactive. Allows very high outlet temperatures for industrial heat applications.

Tristructural isotropic fuel: uranium encased in ceramic layers that cannot melt. Each particle acts as its own micro containment vessel.

US nuclear projects historically require 7–10 years from construction permit to first power. The 2034 target assumes factory-built modular components and no major regulatory delays.

Site not yet selected. Selection typically occurs 2–3 years before license application, driven by grid capacity, water access, and state regulatory climate.
