Nuclear outage schedule 2026-27

Power figures come from the NRC daily reactor status report. We store one row per operating unit from 1999 through the report dated Oct 30, 2026. The reason text comes from the NRC's daily pages, which add a comment about 28 days after the power figure. Those comments cover the last five years.

An outage is a run of days at 0% power. A hole of up to 3 days with no report stays in the same outage. If the unit comes back below 30% for 3 days or fewer and then returns to 0%, that is still one outage.

Each outage gets a score from the signals below.

• A score of 4 or more is a refueling.
• A maintenance comment without a refueling comment is maintenance.
• A score of 0 or less under 14 days is unplanned.
• Anything else stays offline: we do not have enough to name it.

For a unit that is not in a refueling outage, the next start is the last refueling start plus the median gap between its last five refueling starts. The window is that date, plus or minus the larger of 21 days and the spread of those gaps. With fewer than two gaps, we use 18 months. If that date is already past and the unit is still up, we show "Due now" for up to 90 days, then step forward by whole cycles. We do not show a forecast date that has already passed.

Forecast is the cycle estimate. Coasting down means the unit is already losing power in the pattern that usually comes before a refueling. Once the outage has started, the unit leaves the forecast table and appears under in outage now.

We read the NRC file twice a day. The date on this page is the report date in that file.

The NRC describes the daily status report as unevaluated information. Nuclear Hustle is not the NRC and is not affiliated with any plant operator. A forecast is an estimate from past outages. It is not a date the operator has scheduled.
