?
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.

NukeWorker's Operational Excellence Score is a composite 0–100 ranking of every active US nuclear unit across 7 measured performance metrics, grouped into three sub-scores:
• Reliability — capacity factor, forced outage days, B2B avg streak
• Efficiency — fuel utilization, refuel duration
• Discipline — startup duration, scram count
Each unit's metric is converted to a percentile across the active fleet. Sub-score = average of its components; composite = average of the three sub-scores. Use the time-window toggle below to switch between 3yr / 5yr / lifetime.

?
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.
?
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.
?
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, flat stretches near the top are full-power running and drops to zero are outages.
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.
