A project is a deal in the order book: a reactor with a customer, or a self-build of a commercial plant. Demonstration articles are on Race to Full Power. The rungs are the same for every regulator — NRC, CNSC, DOE and the Army each map their own steps onto them. COD is each deal's own published date.
