NukeWorker's Spring 2026 Nuclear Plant Outage Schedule
The published refueling and maintenance outage schedule for the entire US commercial reactor fleet, aggregated in one place and kept current. We track every utility's scheduled dates and alert you the moment they change. Where a utility has not published its dates yet, our Predictive Model (which is 99.7% accurate) fills them in, and for every outage we forecast how far it may run past schedule, 83.2% more accurately than the utilities themselves.

|---|---|
| Unit | The reactor unit, normalized to a consistent name, linked to its full outage history. |

| Duration | How many days the outage is scheduled to run. |
| Projected Extension | How far past the scheduled return our Predictive Model expects the outage to run, weighted on history. |
