7-Dimension Radar Each axis = percentile rank in the active US fleet (higher = better)
Per-Dimension Percentile Breakdown
| Dimension | Millstone 3 |
|---|---|
| Capacity Factor 5-year average capacity factor — total generation as a fraction of installed capacity. Higher is better; top operators sustain 92%+. |
29
89.1%
|
| Forced Outage Days/yr 5-year forced outage days per year (annualised) — non-power days NOT explained by scheduled refueling. Lower is better. |
11
16.0d
|
| B2B Avg Streak Average breaker-to-breaker continuous-operation days across this unit's qualifying B2B runs (lifetime). Higher is better; reflects sustained reliability. |
44
512d
|
| Fuel Utilization Average in-cycle capacity factor (3-year). Fraction of each refueling cycle that produced full power. Higher = more efficient operator. |
5
92.8%
|
| Refuel Duration 5-year median scheduled refueling outage duration in days (refuel-shaped outages, 14-90d). Lower = faster turnaround. |
13
41d
|
| Startup Duration Robust mean days from first power post-refuel to sustained ≥95% power. Lower = faster ramp. |
63
3.9d
|
| Scrams (5-year) Scrams per year, computed over the 5-year window (annualised so windows are comparable). Lower is better; reflects operating discipline and equipment reliability. |
