ReactorScale

Coverage of advanced nuclear often blends reactor designs under regulatory review with projects at named sites, which makes the pipeline look further along than it is. I wanted development status separated out.

Tracks U.S. advanced nuclear development with site-specific projects kept apart from design-level activity, so headline capacity does not quietly combine the two. Each record carries its own sources and dates, and findings that look plausible but are unconfirmed sit in a review queue instead of in the totals. Operating fleet figures come from EIA-860 and EIA-923.

The registry is assembled from public sources and is not a complete census of the sector, so an absence should be read as unconfirmed rather than as evidence that nothing is happening. Updates are semi-manual, which means the data reflects when it was last reviewed rather than continuous monitoring.
