## In brief

- Ontario Power Generation said in a Tuesday earnings release that the first BWRX-300 unit at its Darlington site will not come online by its original target date.
- The project is running late and over budget, according to Canary Media, which describes it as North America's first small modular reactor project.
- The source article is truncated, so the new target date and the size of the cost overrun are not confirmed here.

## Why it matters

Delays and cost overruns in the first North American small modular reactor project can shape how utilities and regulators judge the cost and schedule of future SMR builds.
