Operational Excellence Score Subscribers
Every operating US reactor rated 0 to 100 on how well it actually runs, scored from its own operating record rather than from anything a utility publishes about itself. Subscribers see the honor roll, the full ranking and the seven measured inputs behind every score.
- Composite score for every operating unit
- Reliability, Efficiency and Discipline sub-scores
- The seven measured inputs behind each score
- Fleet percentile and peer-group rank per unit
- Year-over-year trend for every unit
- Operator-level fleet leaderboard
Included with every outage subscription and with NukeWorker Gold membership. Trading the outage rather than working it? The same record, cut by power market, is on NukeGryd.

Outage Duration
Per-unit average scheduled outage duration over the last 5 years. Shorter outages rank higher — but longer outages mean more work for outage workers.

Fuel Utilization
Average in-cycle capacity factor — fraction of each refueling cycle (refuel-to-refuel) that produced full power. Higher = more efficient operator (refuels closer to coastdown, fewer derates, faster startup ramp). Top quartile units typically run 99%+ in cycle. Excludes Vogtle 4 (insufficient cycle history).

Startup Duration
Typical days from first power generation (>0%) post-refuel to sustained full power (≥95% for 2+ days). Robust mean — drops outliers like post-major-outage startups. Lower is faster restart. Top quartile operators get back to full power in 2-4 days.
