Nuclear Safety Authority of France (ASN)

What Nuclear Safety Authority of France (ASN) does

The Autorité de sûreté nucléaire et de radioprotection (ASNR) is France's independent administrative authority for nuclear safety and radiation protection. It was formed on January 1, 2025 through the merger of the Autorité de sûreté nucléaire (ASN) and the Institut de radioprotection et de sûreté nucléaire (IRSN), pursuant to the law of May 21, 2024 on the organization of nuclear safety and radiation protection governance. ASNR exercises statutory regulatory oversight over all nuclear installations in France — approximately 50 nuclear power reactors, nuclear fuel cycle facilities including the UP2-800 and UP3-A processing plants, nuclear research facilities, and nuclear activities in the medical, industrial, and veterinary sectors. It is funded by the French state and reports annually to the President of the Republic, Prime Minister, and Parliament via the mandated report on the state of nuclear safety and radiation protection in France.

ASNR's operational scope encompasses inspection of nuclear installations, periodic safety reviews, authorization of reactor operations and decommissioning (including the Fessenheim plant), oversight of EPR2 and Small Modular Reactor programs, radiation protection in medical imaging and radiotherapy, regulation of industrial radioactive source use, and control of radioactive substance transport. It operates an incident notification system using the international INES scale and the ASN-SFRO classification for medical events, and conducts public consultations on regulatory decisions with environmental impact. The authority's digital infrastructure spans three transitional websites — reglementation-controle.asnr.fr (regulatory and control content), asnr.fr (main site), and recherche-expertise.asnr.fr (research and expertise content inherited from IRSN) — with a consolidation into a single unified site underway.

ASNR's business model is non-commercial. As a publicly funded regulatory body, it generates no revenue, charges no fees for regulatory services, and has no shareholders. Its "customers" in a regulatory sense are the nuclear operators and radiation users it oversees — primarily EDF (power generation and decommissioning), Orano (fuel cycle operations), and healthcare/industrial/veterinary entities handling radioactive materials. Its value proposition is statutory enforcement of nuclear safety standards and radiation protection rather than commercial product delivery, and its outputs are regulatory decisions, inspection reports, official bulletins, incident notices, and the annual report mandated under Article L.592.31 of the Environment Code.

Core offering

ASNR is the French independent administrative authority that regulates nuclear safety and radiation protection across all nuclear installations and activities in France. It oversees approximately 50 nuclear power reactors, nuclear fuel cycle facilities (including UP2-800 and UP3-A), medical nuclear activities, industrial uses of radioactive substances, veterinary radiation applications, and radioactive substance transport. ASNR issues authorizations, conducts inspections, classifies incidents via the INES scale, manages periodic safety reviews, and runs public consultations on regulatory decisions.

Product overview

ASNR (Autorité de sûreté nucléaire et de radioprotection) is a French government regulatory authority formed on January 1, 2025 through the merger of ASN and IRSN. Rather than a commercial product company, ASNR provides regulatory oversight services organized around several interconnected digital platforms and service categories. The primary regulatory and control website (reglementation-controle.asnr.fr) serves as the main portal for nuclear installation oversight, medical and industrial activity regulation, public consultations, incident notifications, and official bulletins. A separate research and expertise website (recherche-expertise.asnr.fr) hosts technical and scientific content. ASNR services span nuclear installation control, reactor monitoring, periodic safety reviews, dismantling authorization, medical and industrial nuclear activity regulation, radioactive substance transport oversight, and public participation mechanisms. The annual report on nuclear safety and radiation protection constitutes a major annual deliverable, while the external alert system and online administrative services support ongoing regulatory compliance.

• Swedish Radiation Safety Authority (SSM): SSM is Sweden's combined regulator for radiation protection and nuclear safety, formed by merging predecessor authorities — directly parallel to ASNR in its combined nuclear and radiation protection mandate and merger-driven consolidation.
• UK Office for Nuclear Regulation (ONR): The ONR is the UK's independent nuclear regulator with statutory authority over civil nuclear installations, security, and safeguards — closely parallel to ASNR in mandate, governance structure (independent statutory body), and regulatory scope.
• German Federal Office for Radiation Protection (BfS): BfS is the German federal regulator for radiation protection and nuclear safety oversight, including radioactive waste management — comparable to ASNR's radiation protection functions and federal oversight role.
• Korea Nuclear Safety and Security Commission (NSSC): The NSSC is South Korea's independent nuclear safety and security commission overseeing reactors, radiation uses, and safeguards — comparable in scope and independent regulatory authority to ASNR.
• U.S. Nuclear Regulatory Commission (NRC): The NRC is the U.S. federal regulator responsible for nuclear safety, security, and radiation protection — directly comparable to ASNR as a national nuclear safety authority with comparable scope over power reactors, fuel cycle, and radiation uses.
• Canadian Nuclear Safety Commission (CNSC): The CNSC is Canada's independent nuclear regulator covering reactors, fuel cycle, medical/industrial uses of radiation, and radioactive materials transport — a near-direct functional analog to ASNR's combined mandate.
• Spanish Nuclear Safety Council (CSN): The CSN is Spain's independent nuclear safety and radiation protection regulator with jurisdiction over the Spanish nuclear fleet and radiation uses — directly comparable to ASNR in scope and governance model.
• Finnish Radiation and Nuclear Safety Authority (STUK): STUK is Finland's nuclear and radiation safety regulator, including oversight of EPR-class new builds and spent fuel disposal — directly comparable to ASNR's nuclear safety oversight and EPR2-style new-build responsibility.
• Nuclear Regulation Authority of Japan (NRA): Japan's NRA is the independent regulatory authority established post-Fukushima to oversee nuclear safety, radiation protection, and safeguards — directly comparable to ASNR in scope and statutory independence.

Broad incumbents

• International Atomic Energy Agency (IAEA): The IAEA is the global intergovernmental forum that sets nuclear safety standards (e.g., IAEA Safeguards) and conducts inspections — overlapping with ASNR's mandate but operating globally rather than nationally, and as a standards-setter rather than a domestic licensor.
