Benchmark historical performance across a quarter-century of fleet-wide reactor data. Track long-term maintenance trends, refueling cycles, and realized generation impacts from 2000 to the present. Data refreshed 18.1h ago
This timeline maps 28 reactor outages across the US fleet for Fall 2026. That includes 18 completed refueling outages, 5 unplanned outages, and 5 reactor trips. The longest ran 41 days at North Anna 2 and 15 reactors are offline right now.
The table below lists each outage with its exact start date, end date, and duration. Completed outages during Fall 2026 averaged 17 days. Refueling outages also show the plant's own cycle designator next to the type (for example 1R23); outages with no recorded designator show none.
