What changed in the data
62 corrections to the source data across 31 reactors, each with the source that supports it, and 8 changes recorded between data refreshes.
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.

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.
