The outside view

The policy organization of the nuclear energy industry, the unified voice for commercial nuclear power in Washington, coordinating the industry on regulation, safety, and public confidence in nuclear generation

  • Authority
  • Preserve
  • Outward
  • Operational

Their shape

The League

Far-flung, and stronger for it.

The League is a federation of many, where the value lives in the connections between its members and chapters. Its gift is reach and resilience, its challenge is holding a shared identity across all its parts.

Also reads toward The Citadel and The Parliament.

Strengths

→Coordinated scale that punches above its weight.
→Ambition matched by professional execution.
→A credible, unified voice for many.
