?
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). Computed as 100% minus the unit's average refuel-point fuel %, using the last 3 years where available, otherwise lifetime average.

?
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

Crystal River 3 has 23 outages plotted here, averaging 11 days each. The most recent, in Aug 2009, was a unplanned outage lasting 1 day.
?
Days between consecutive scheduled refueling outage starts, showing operating cycle regularity. The purple dashed line marks the average cycle length. Most U.S. reactors operate on 18-month (547 day) or 24-month (730 day) cycles.

Cycle Length History

Between refueling outages, Crystal River 3 runs about 739 days, or roughly 24 months, per cycle. That average comes from 4 completed cycles, the most recent lasting 735 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, Crystal River 3 takes about 4 days to climb from first power back to full power. That average is drawn from 5 startups on record, and the most recent took 2 days.
?
Monthly capacity factor with outage events overlaid as red bands. Green bars show average power level per month. Toggle to Daily view for raw daily data.

Power History

Over its operating life, Crystal River 3 has run at about 68.2% of its rated capacity. Across the last 12 reported months it averaged 0.0%. On the chart, flat stretches near the top are full-power running and drops to zero are outages.
This table logs every recorded outage for Crystal River 3, 24 in all since 1999. Of those, 6 were scheduled refueling outages and 18 were unplanned or forced. The typical outage lasted about 67 days. Where the Scheduled column shows (Model), the date is a NukeWorker projection because the utility had not published one.
