Read the milestone
The right status belongs to a specific project, source and jurisdiction.
Use a plain status vocabulary
A technology can be in development while a different design from the same supplier is operating. A construction permission can apply to one unit while plans describe a larger site. An operating licence application is an application, not an authorization.
One example of the distinction
The Canadian regulator describes one BWRX-300 under construction at Darlington. It separately records the operating-licence application made in March 2026. These facts should not be compressed into a claim that an SMR is already operating there.
Build a source trail
Record the responsible organization, the date and the specific milestone. A corporate announcement can establish what a company said; a regulator’s decision is the better source for what that regulator authorized.
Our Project Lens deliberately presents a few dated examples, rather than a claim to be a comprehensive or live project database.
