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 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, Hope Creek 1 has spent 628 days in scheduled refueling outages and 187 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
Hope Creek 1 has 59 outages plotted here, averaging 14 days each. The most recent, in Feb 2026, was a unplanned outage lasting 13 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
Hope Creek 1 has completed 19 scheduled refueling outages on record, averaging 33 days each. The most recent, in Sep 2025, ran 36 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, Hope Creek 1 takes about 6 days to climb from first power back to full power. That average is drawn from 19 startups on record, and the most recent took 7 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
11 of 19 refuelings
29 days median
87% power at shutdown
0.3% per day
Hope Creek 1 coasted down for a week or longer before 11 of its 19 refuelings on record. Those coastdowns ran a median of 29 days and ended near 87% power. The most recent refueling, in Sep 2025, followed a 29-day coastdown from 97% to 87%.
?
Estimated fuel remaining in the current cycle, expressed as a percentage of the unit's typical cycle. Starts at 100% when the unit returns to power post-refuel and drops as full-power-days are burned. Days at reduced power burn fuel proportionally — so a unit with significant downtime (high burn deficit) drops slower and ends up with MORE fuel left than its calendar position would suggest. Coastdown threshold around 15%. Toggle to overlay past cycles on a normalized "days into cycle" axis to see how aggressively this unit historically burns down before refuel.

Power History
Over its operating life, Hope Creek 1 has run at about 88.8% of its rated capacity. Across the last 12 reported months it averaged 93.6%. 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.
Estimated reactivity remaining in Hope Creek 1's current fuel cycle, shown as a stylized fuel rod that drains as the cycle progresses. The cycle starts when the unit returns to power after its most recent refueling outage, and the gauge represents the fraction of that cycle's typical effective full-power days (EFPD) still available. Days at less than 100% power burn fuel proportionally — so a unit with significant downtime (high burn deficit) drains slower and ends with MORE reactivity left, giving operators margin to coast down (extend the cycle by reducing power) instead of refueling on the calendar. The dashed red line near the bottom marks the rough industry coastdown threshold (~15% remaining). Cycle target is the unit's median recent cycle length.

Fuel Burn Down Cycle since Nov 3, 2025
Hope Creek 1 is 339 days into its current fuel cycle with an estimated 36.2% of its fuel left. Its typical cycle runs about 501 days.

Hope Creek 1 is mid-cycle with healthy reactivity. Operators have flexibility to defer or advance the next refuel as needed.
This unit has accumulated 19.3 FPD of unburned fuel from cycle downtime — that's free margin to extend the cycle if operators want.

Outage History & Daily Power Log
This table logs every recorded outage for Hope Creek 1, 59 in all since 1999. Of those, 19 were scheduled refueling outages, 4 were planned maintenance and 36 were unplanned or forced. The typical outage lasted about 14 days. Where the Scheduled column shows (Model), the date is a NukeWorker projection because the utility had not published one.
