Only one track pairs a named reactor with a named site under a signed instrument. Open any row for its full fields and sources.
What it costs against what it displaces
No microreactor has sold power commercially, so nothing here is a realised price. Each band is wide because its sources disagree about first-of-a-kind capital cost versus manufacturing scale, and that disagreement is the useful part.
Antares, Radiant and Westinghouse
In April 2026 the Air Force and DIU paired these three companies with three named bases under the ANPI programme,[?] which is why they are the three covered here. Each card carries a cited roadmap to first power.
Which loads fit a 1–20 MW block
These are annual-average demand bands for planning. Real sizing needs a year of hourly site-load data before anyone commits to a number. Each sector opens with how it powers itself today and what a microreactor would replace.
A shared orderbook and an overrun pool
Regulatory pathways
The rules that decide whether a microreactor can replace diesel backup, pair with batteries, or connect faster. Rows marked idea are proposals from this research. They are not enacted policy and carry no citation.
