Outage Days by Year

?
Total days spent in outage each year, split by scheduled refueling (blue) and forced/unplanned (red). Lower totals indicate better reliability and outage execution. Hover for details.
Across its recorded history, Farley 2 has spent 722 days in scheduled refueling outages and 52 days in forced or unplanned outages. Taller bars mark the years with the most downtime.
?
Duration of each outage in days, shown chronologically. Green bars are scheduled refueling outages, red bars are forced/unscheduled. The orange dashed line marks the average duration. Extended outages (>180 days) and D&D periods are excluded.

Outage Duration Trend

Farley 2 has 38 outages plotted here, averaging 20 days each. The most recent, in Oct 2026, was a scheduled refueling outage lasting 4 days.
?
Scheduled refueling outage durations over time. Green bars are at or below this unit's average, amber up to 30% above it, red beyond that. The dashed line is the average. Shorter outages mean better execution.

Refueling Duration Trend

Farley 2 has completed 19 scheduled refueling outages on record, averaging 38 days each. The most recent, in Oct 2026, ran 4 days.
?
Time in days from first power generation (>0%) to sustained full power (≥95% for 2+ consecutive days) after each scheduled refueling outage. The dashed line marks the average. Includes startup testing holds and power dips.

Startup Duration Trend

After a refueling outage, Farley 2 takes about 6 days to climb from first power back to full power. That average is drawn from 18 startups on record, and the most recent took 4 days.
?
Daily reactor power over the 120 days before each scheduled refueling outage, one line per refueling, lined up on the day the outage began. A coastdown is the slow decline as the fuel runs out near the end of a cycle. The highlighted line is the most recent refueling and fainter lines are older. Counts and medians cover coastdowns of a week or longer. A shutdown straight from full power, with no decline ahead of it, is what a forced outage looks like.

Coastdown Before Refueling

14 of 19 refuelings 11 days median 88% power at shutdown 0.9% per day
Farley 2 coasted down for a week or longer before 14 of its 19 refuelings on record. Those coastdowns ran a median of 11 days and ended near 88% power. The most recent refueling, in Oct 2026, followed a 7-day coastdown from 97% to 93%.

Power History

Over its operating life, Farley 2 has run at about 90.8% of its rated capacity. Across the last 12 reported months it averaged 98.3%. On the chart, green stretches near the top are full-power running, amber marks reduced power (50 to 89%), and red drops toward zero are outages.

Outage History & Daily Power Log

This table logs every recorded outage for Farley 2, 38 in all since 1999. Of those, 19 were scheduled refueling outages, 1 was planned maintenance and 18 were unplanned or forced. The typical outage lasted about 20 days. Where the Scheduled column shows (Model), the date is a NukeWorker projection because the utility had not published one.
