What we look for

An application submitted, an application accepted for review and a permit issued are three different states. A construction authorisation is not an operating licence. Fuel supply, financing and customer agreements are tracked apart from the reactor itself.

Coverage limits

Regulatory coverage is strongest where the regulator publishes dated notices we can read directly. Projects outside those jurisdictions are followed through the parties' own statements, labelled as such.

The projects below are the ones we maintain, not a census of the field. Sources and their last successful checks.
