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 16.9h ago
This timeline maps 36 reactor outages across the US fleet for Fall 2026. That includes 22 completed refueling outages, 7 unplanned outages, and 7 reactor trips. The longest ran 60 days at North Anna 2 and 18 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 23 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.
