?
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, Oyster Creek has spent 251 days in scheduled refueling outages and 185 days in forced or unplanned outages. Taller bars mark the years with the most downtime.
Performance Trends
?
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
Oyster Creek has 50 outages plotted here, averaging 9 days each. The most recent, in Jul 2017, was a unplanned outage lasting 2 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
Oyster Creek has completed 9 scheduled refueling outages on record, averaging 28 days each. The most recent, in Sep 2016, ran 23 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, Oyster Creek takes about 4 days to climb from first power back to full power. That average is drawn from 9 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
3 of 9 refuelings
23 days median
90% power at shutdown
0.3% per day
Oyster Creek coasted down for a week or longer before 3 of its 9 refuelings on record. Those coastdowns ran a median of 23 days and ended near 90% power. The most recent refueling, in Sep 2016, followed a 7-day coastdown from 97% to 95%.

Power History
Over its operating life, Oyster Creek has run at about 88.7% of its rated capacity. Across the last 12 reported months it averaged 41.5%. 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.
