Updated every morning from the NRC Daily Power Reactor Status Report.Next Outage
IndividualThe utility's own published date for this unit's next refueling outage, its RFO number, and how far past that date it has historically run.
Published outage dates for every U.S. reactor, plus the probabilistic curve behind them.
- Published start date + duration
- The utility's own RFO designator
- Projected overrun in days
- Confidence on every date
Operational Excellence
IndividualOne 0-100 score for how well this unit actually runs, computed from 27 years of daily reactor records: capacity factor, forced-outage days, breaker-to-breaker streak, fuel utilization, refuel duration, startup speed and scram rate. Sub-scores for reliability, efficiency and discipline, and its rank against units of the same reactor type and containment, and against units on a comparable fuel cycle.
Operating Timeline
IndividualEvery outage this unit has taken, year by year, color-coded refuel against forced, with each refueling outage carrying its own RFO designator.
Twelve years of this unit's outages on one timeline, so a published date can be read against what actually happened.
- Refuel vs forced vs scram, color-coded
- RFO designators on every refueling outage
- Duration and coastdown on hover
Outage Record
Refueling outages separated from forced ones, the distinction that decides whether a date is worth believing.
- Start, end and duration
- Refuel / forced / scram classification
- RFO designator and cycle number
- Coastdown and startup days
If It Trips
ProNobody schedules a scram. When one happens the only question on a desk is how long the megawatts are gone, and that is a number no incumbent publishes. This is our projection for Browns Ferry 2, scored against this unit's own trip history.
A trip is the one supply event nobody sees coming. The projection above says how long it lasts, and we publish how close that call has landed on this unit's own history.
- Days down per unit if it trips
- Scored against each unit's own trips
- Projected outage overrun
- MW-days the market has not priced
Breaker-to-Breaker Streak
IndividualHow long this unit has run continuously since its last refueling outage without an unplanned shutdown, the industry's own badge of a well-run reactor, plus its completed streak history, whether it is a B2B champion, and how many days it has gone without a trip.
Reactor Trips
IndividualEvery reactor trip the NRC has recorded for this unit, each with its event number and the licensee's own description.
Every scram the NRC has recorded for this unit, with the event notification behind it.
Plant Record
NRC and EIA filingsCapacity over time
Net summer capability as filed with EIA. This unit is +104 MW (+9.4%) against its earliest record, across 1 step large enough to be a real uprate. Smaller moves are EIA restating the same machine, not megawatts being added.
