Sources behind the reactor data
Every curated reactor entry links to the source used for its current snapshot. Where programme status changes faster than technical specifications, the linked source remains the authority.
How we choose a source
Vendor, operator, regulator, government or project-owner material is preferred for design specifications and programme milestones.
IAEA PRIS and established nuclear-industry databases are useful for operating-fleet context and cross-checks.
A selection, test, licence filing or construction milestone is not rewritten as commercial operation. The exact status phrase remains visible on the reactor profile.

How freshness works
Technical design values often move slowly; project status can change in days or months. Each profile therefore shows a verification date. The development tracker is a dated snapshot, not live telemetry.
See something stale or wrong?
Use the correction workflow. The most useful report includes the reactor name, the field that appears wrong, and a regulator, operator, government or vendor source that supports the correction.
