Average fuel utilization — percent of the designed fuel cycle that this unit consumes before refueling, derived from the historical burn-down trajectory. Higher = more efficient operator (refuels with less margin remaining; closer to coastdown).

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, North Anna 2 has spent 812 days in scheduled refueling outages and 208 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

North Anna 2 has 48 outages plotted here, averaging 21 days each. The most recent, in Sep 2026, was a scheduled refueling outage lasting 38 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

North Anna 2 has completed 19 scheduled refueling outages on record, averaging 43 days each. The most recent, in Sep 2026, ran 38 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, North Anna 2 takes about 4 days to climb from first power back to full power. That average is drawn from 18 startups on record, and the most recent took 3 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

5 of 19 refuelings 17 days median 87% power at shutdown 0.5% per day
North Anna 2 coasted down for a week or longer before 5 of its 19 refuelings on record. Those coastdowns ran a median of 17 days and ended near 87% power. The most recent refueling, in Sep 2026, followed a 18-day coastdown from 96% to 87%.

Power History

Over its operating life, North Anna 2 has run at about 89% of its rated capacity. Across the last 12 reported months it averaged 84.2%. 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 North Anna 2, 48 in all since 1999. Of those, 19 were scheduled refueling outages and 29 were unplanned or forced. The typical outage lasted about 21 days. Where the Scheduled column shows (Model), the date is a NukeWorker projection because the utility had not published one.
