Institute of Nuclear Power Operations

What Institute of Nuclear Power Operations does

The Institute of Nuclear Power Operations (INPO) is an independent, non-profit organization founded in December 1979 in Atlanta, Georgia, in response to the Kemeny Commission's recommendations following the Three Mile Island accident. It functions as the industry's self-regulatory authority for commercial nuclear safety and reliability in the United States, with all NRC license holders required to maintain continuous membership. INPO also operates WANO's Atlanta Center and supports international operators in China, Romania, South Africa, and the UAE.

INPO's core offerings revolve around an integrated membership platform anchored by the National Academy for Nuclear Training (NANT), which holds exclusive NRC recognition as the independent accreditation for operator and technical training. The organization delivers peer reviews, confidential performance assessments, integrated performance monitoring, member support missions, and the New Unit Assistance Program for new nuclear deployments. Its proprietary technology stack sits on top of the industry's largest operating experience data repository, spanning thousands of reactor-years and analyzed by in-house data scientists to produce benchmarking, trend analysis, and predictive insights delivered through member-facing reporting systems. INPO also sets industry standards (e.g., INPO 26-001) and runs the Supplier Participant Program (SPAC) engaging 25+ major suppliers.

The revenue model is subscription/membership-based, with 22 U.S. utility members, associate members for joint owners, and voluntary supplier participants. The organization employs 101-250 staff and reports over 90% employee engagement. Strategic partners include WANO, NEI, the NRC, EPRI, DOE, IAEA, ANI, NEIL, and JANSI, situating INPO at the center of the global nuclear industry governance ecosystem.

Direct peers

• World Association of Nuclear Operators (WANO): WANO is the global sister organization to INPO, and INPO operates WANO's Atlanta Center. WANO pursues the same mission of operational nuclear safety excellence across 120+ members and 430+ reactors worldwide, making it the most directly comparable peer.
• Japan Nuclear Safety Institute (JANSI): JANSI is Japan's nuclear industry self-regulatory counterpart to INPO, established post-Fukushima to coordinate self-regulation and pursue operational excellence. It performs a near-identical role as INPO does for the US fleet, making it a structural international peer.

Broad incumbents

• Nuclear Energy Institute (NEI): NEI is the US nuclear industry's policy and advocacy organization, addressing legislative and regulatory issues for nuclear technologies. While NEI operates in policy/advocacy (not operations excellence), it is one of INPO's core partners and a peer in industry self-regulation infrastructure.
• Electric Power Research Institute (EPRI): EPRI is an independent, non-profit energy research, development, and deployment organization that conducts collaborative research for the electricity sector including nuclear. It complements INPO by providing technology and R&D, whereas INPO focuses on operational excellence — together serving overlapping utility memberships.
• International Atomic Energy Agency (IAEA): IAEA is the global intergovernmental forum for nuclear safety and peaceful uses of nuclear technology. While it sits at a higher, intergovernmental level, it is one of INPO's core partners and overlaps in operational safety standards, peer review frameworks, and operator support missions.

Regional players

• Korea Institute of Nuclear Safety (KINS): KINS is the South Korean nuclear safety research and self-regulatory organization supporting Korean nuclear operators. While its scope extends to regulatory research, it parallels INPO's role as the technical excellence backbone for a national nuclear fleet.
• Autorité de Sûreté Nucléaire (ASN): ASN is the French independent nuclear safety authority that also performs quasi-regulatory oversight and operational benchmarking for the French fleet. As a regulator it is structurally different, but its operator performance and peer-review functions parallel part of INPO's mandate.
• Office for Nuclear Regulation (ONR): ONR is the UK's independent nuclear regulator covering operational safety across the UK civil nuclear fleet. Like INPO it serves as the institutional backbone of operational nuclear safety for its national fleet, though as a regulator rather than industry self-regulatory body.
• Canadian Nuclear Safety Commission (CNSC): CNSC is Canada's federal nuclear regulator, conducting licensing, compliance and operator performance oversight for the Canadian fleet. As a national nuclear regulator covering an adjacent geography, it is a regional peer in institutional nuclear excellence oversight.

Others

• American Nuclear Insurers (ANI): ANI is the US nuclear liability insurance joint underwriting association that writes nuclear facility insurance and assumes reinsurance for nuclear pools worldwide. It is an adjacent ecosystem participant and INPO partner, addressing risk rather than operational excellence, but serving the same nuclear operator customer base.
