Notes:
1. Data Sources: Power generation data sourced from U.S. Nuclear Regulatory Commission (NRC) Daily
Status Reports. Lifecycle and technical data from NRC and EIA records.
2. Capacity Factor: Calculated as (Net Generation / Net Capacity), where Net Generation is derived from
daily power levels. Excludes units after their official decommissioning date.
3. B2B Runs: "Breaker-to-Breaker" refers to a continuous operating cycle between refueling outages with
zero breaker trips (0% power) in between.
