The Nuclear Energy Institute (NEI) is a Washington, D.C.-based policy organization founded in 1994 that serves as the primary trade association for the nuclear energy industry in the United States. The organization represents nearly all U.S. nuclear power plant operators, nuclear plant designers, engineering and construction firms, fuel suppliers, and other companies involved in the nuclear energy sector. NEI develops policy positions and advocates on behalf of the nuclear industry before Congress, federal agencies, and state governments. The organization focuses on issues such as nuclear safety, waste management, nuclear plant operations, security, and regulatory frameworks. It also works to promote public understanding of nuclear technology and its role in clean energy production. The institute provides technical and policy expertise to its members, conducts research, and maintains databases on industry performance indicators. NEI plays a significant role in shaping nuclear energy policy through its engagement with regulatory bodies, particularly the Nuclear Regulatory Commission (NRC). The organization also coordinates industry-wide initiatives on emergency preparedness, workforce development, and cybersecurity. NEI regularly publishes reports, policy papers, and educational materials about nuclear energy and maintains partnerships with international nuclear organizations to share best practices and promote global nuclear safety standards.
