The United States is building nuclear reactors again, on every front at once. New designs are going critical, large reactors are being announced, and plants already running are being pushed harder or brought back. These trackers follow all of it: who's ahead, what it costs, and how the machines work.
Four finish lines for advanced reactors, in order.
Which advanced reactor goes critical first under the DOE pilot program.
Going critical proves a core. Who reaches full electrical power first.
Who is first to run a reactor that sells its power, project by project.
Every announced route to a gigawatt on the grid, and how much of it is firm.
Running alongside.
Every dated goal in the May 2025 nuclear orders, and where each one stands.
Six military bases racing a 2028 deadline to run a reactor, and where each stands on permits.
Every machine on the way to a commercial-scale demo, and what each one proves.
Who has agreed to buy how many megawatts, and how much of it is firm.
Every sited design and firm order on a US map.
Who has a reactor production line, and how it compares with demand.
The supply chain from mine to repository, and who is rebuilding each stage.
Cost of electricity compared across designs, with inputs you can change.
Every developer: the machines they are building, their designs, orders and news.
Every reactor in one spec table.
The design choices, the common archetypes, and which reactors fit each.
Regroup every design by size, fuel, coolant and more, and see where they overlap.
Every design on one timeline, from approval to commercial operation.
