The Carbon Factor Arrives Five Years Before the Reactor
The carbon footprint factor becomes institutionally operative roughly five years before grid connection, so recognition timing governs feasibility more than generation timing.

The Xuwei dual-reactor configuration has been widely reported as a technical breakthrough. Reading it as a technical event misses the part that actually carries institutional force.
Product carbon footprints are calculated under ISO 14067, where the emission factor for purchased steam depends on its source. That difference is one number on a report and an entire cost line in a CBAM embedded emissions declaration.
The gap between institutional and engineering timelines
Grid connection has a defined engineering schedule. The institutional force of a carbon footprint factor does not wait for that date.
What replicability actually requires
Whether the Xuwei model travels depends on three conditions holding simultaneously. The third is the one most often overlooked, and the one that decides the economics.
