?
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.

Outage Record

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, Crystal River 3 has spent 175 days in scheduled refueling outages and 81 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

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.
?
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

Crystal River 3 has completed 5 scheduled refueling outages on record, averaging 35 days each. The most recent, in Nov 2007, ran 34 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.
?
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

2 of 6 refuelings 23 days median 80% power at shutdown 0.5% per day
Crystal River 3 coasted down for a week or longer before 2 of its 6 refuelings on record. Those coastdowns ran a median of 23 days and ended near 80% power. The most recent refueling, in Sep 2009, began with no extended coastdown.

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, green stretches near the top are full-power running, amber marks reduced power (50 to 89%), and red drops toward zero are outages.
