Fleet Facility Rankings

Community ratings ranked by Bayesian average with INPO-style quartile bands. Vote to share your experience.

Total number of nuclear facilities (active and decommissioned) that have received at least one community vote.

105

Facilities Rated

Bayesian average adjusts raw scores based on vote count — facilities with few votes are pulled toward the fleet average, so rankings reflect confidence, not just raw percentages.

52.3

Fleet Average

Bayesian score

Minimum Bayesian score to rank in the top 25% of active facilities. Quartile bands follow the INPO performance indicator model used across the nuclear industry.
