US nuclear reactor status

The Nuclear Regulatory Commission publishes the power level of every US commercial reactor each business day. This page shows the most recent report for all 95 units in that feed, 102.5 GW of operating capacity, with units below full power listed first.

Also: outage history · outages outside the US · earthquakes near plants

Fleet availability, past year

Capacity-weighted share of the operating fleet online each day. The twin troughs are the spring and autumn refuelling seasons, when utilities take units down deliberately.

Every unit

Units below full power appear first. The NRC feed carries no reason for a reduction, it is three columns: date, unit, power percentage. A unit at 0% may be refuelling, in a planned outage, or tripped, and this page will not guess which.
