What changed in the data
54 corrections to the source data across 27 reactors, each with the source that supports it.
The fleet data starts from the Global Nuclear Power Tracker (August 2026 release). Where we depart from it, the page for that reactor shows the old value, the new value and the source; this page gathers them all. Subscribe with the Atom feed, or download every correction as a CSV.
Changes recorded between data refreshes
Nothing yet. A snapshot of the fleet data was taken on 22 October 2026, and each later refresh or correction is compared with it. Anything that changes will be listed here, with the date, so a figure that moves can be explained.
Corrections applied to the source data
Each correction states what was wrong, what the source says, and when we checked it. We correct only what a primary or authoritative source settles; everything else keeps the tracker's value.
