The Year Ahead: Key Events at the IAEA in 2026

Nuclear Energy Summit
10 March, Paris, France.

The second Nuclear Energy Summit will be hosted by the Government of France in Paris. It follows on from a previous nuclear energy summit in 2024, in which world leaders gathered in Brussels to highlight the role of nuclear energy in enhancing energy security and boosting economic development.

International Conference on the Safe and Secure Transport of Nuclear and Radioactive Material 
23–27 March, Vienna, Austria

Every year, around 20 million shipments of nuclear and radioactive material support peaceful uses of nuclear technology in energy, medicine, industry, agriculture and research. In March, stakeholders will convene in Vienna to explore how design certification, regulatory frameworks, supply chains and new technologies can reinforce safety and security across all transport modes.

International Conference on Effective Nuclear and Radiation Regulatory Systems (RegCon2026)
27–30 April, Vienna, Austria

Regulators and stakeholders will share practices for effective, agile and connected regulatory “ecosystems” that keep pace with innovation and emerging challenges. The 2026 edition follows Abu Dhabi 2023 and earlier meetings since 2006, with a focus on sharing good practices and experiences across the global regulatory community to further enhance nuclear and radiation safety and security. 

International Conference on Computer Security in the Nuclear World: Securing the Future (CyberCon26) 
11–15 May, Vienna, Austria

As digital systems play an essential role in all aspects of the management and safe and secure operation of nuclear facilities, CyberCon26 will address computer security and potential threats and risks. The conference will bring together regulators, operators and specialists to explore six core themes from computer security by design to emerging digital technologies. 

5th International Conference on Fast Reactors and Related Fuel Cycles (FR26)
18–21 May, Beijing, China

Fast neutron reactors — and the fuel cycles that support them — are widely recognized as key to the long term sustainability of nuclear power. Compared to conventional thermal reactors, fast reactors can extract far more energy from uranium while significantly reducing high-level radioactive waste. Hosted by China in 2026, FR26 will build on prior conferences (Kyoto 2009, Paris 2013, Yekaterinburg 2017, Vienna 2022), engage young professionals, and spotlight progress in sodium, lead, gas and molten salt cooled concepts, as well as how fuels and fuel cycles can be developed for these advanced systems.

Training Workshop on the Transportable Electron Beam System 
17–19 June, IAEA Seibersdorf Laboratories, Austria

The workshop forms part of the IAEA’s ongoing efforts to strengthen the technical capacity of its Member States in the application of advanced radiation technologies for industrial, environmental and research purposes.

A transportable electron beam system, which can also be loaned out for training and experiments, was launched during last year’s IAEA General Conference.

Second IAEA International Conference on Accelerators for Research and Innovation
22–26 June, Vienna, Austria

Particle accelerators have many applications in science and industry, with significant societal and economic impact in areas such as health, environment, food safety, energy and cultural heritage. The second conference in this series will highlight advances in compact and large facilities, best practices in sustainable operation, and accelerator enabled solutions aligned with the IAEA flagship initiatives Atoms4Food, Atoms4NetZero, NUTEC Plastics, Rays of Hope and ZODIAC.

International Conference on Topical Issues in Nuclear Installation Safety (TIC2026)
29 June–3 July, Vienna, Austria

Since 1998, Topical Issues in Nuclear Installation Safety Conferences (TICs) have provided a global platform to share best practices at nuclear installations, from design, siting and construction to operation and regulation. TIC2026 will emphasize how insights gained from past projects and events can help to make future projects more effective, efficient and safe. The conference will address both continuous safety improvements for nuclear power plants currently in operation and strengthening the safety of advanced designs such as small modular reactors (SMRs) and next generation nuclear power plants.

IAEA General Conference 2026
14-18 September Vienna, Austria

Every year in September, leaders, scientists and representatives of our 180 member countries gather in Vienna for one of the biggest annual events for nuclear decision-making: the IAEA General Conference. Delegates debate and decide on issues that shape the agency’s work — from budgets and programmes to peaceful uses of nuclear science and technology and energy. 

The General Conference helps set the IAEA’s course for the year ahead, ensuring that its activities remain effective, relevant, and responsive to global needs

International Symposium on Standards, Applications, and Quality Assurance in Medical Radiation Dosimetry (IDOS3)
5-9 October Vienna, Austria

Medical radiation dosimetry refers to the science and practice of measuring the dose of ionizing radiation delivered to a patient during diagnostic or therapeutic procedures. IDOS3 will continue the work of previous symposia in 2010 and 2019. These reviewed advances in dosimetry standards, audits and quality assurance across radiotherapy, diagnostic radiology and nuclear medicine, underpinning patient safety and measurement traceability.

Building Resilient Fuel Supply Chains International Conference on Fuel Supply Chain for Sustainable Nuclear Power Development
13–15 October, Vienna, Austria

With countries planning to expand nuclear power to meet climate and energy security goals, the front end of the fuel cycle — from uranium exploration to enrichment and fabrication — faces rising demand. The conference will address conventional fuels and advanced nuclear fuels such as HALEU, which is uranium enriched up to 20%, for advanced reactors.  It will also explore other aspects of the supply chain, such as new fuel design concepts, circular economy approaches and other innovations. An essay competition for young professionals invites early career perspectives ahead of the event.

Nuclear Power Ministerial Conference
27-29 October, Incheon, Republic of Korea

A ministerial level gathering on nuclear power will be hosted by the Republic of Korea from 27 to 29 October 2026 in Incheon. Details will be published on the IAEA events portal.

Symposium on International Safeguards
9-13 November, Vienna, Austria

Held every four years, the IAEA Symposium on International Safeguards brings together global stakeholders in support of IAEA safeguards. It is an opportunity for safeguards regulatory authorities, the research and development community, industry and civil society to identify challenges and opportunities for IAEA safeguards, highlight research, share ideas, and build partnerships. The 2026 symposium follows the 2022 event Reflecting on the Past and Anticipating the Future

6th International Conference on Nuclear Power Plant Life Management (PLiM 6)
7–11 December, Tokyo, Japan

With the average global reactor age now over 30 years, long term operation hinges on effective ageing management of structures, systems and components. The PLiM 6 conference will share strategies, innovations and programme approaches that sustain safety and performance — supporting the long term operation of nuclear power plants beyond 60 years. 

Board of Governors
Vienna, Austria

The IAEA’s Board of Governors will meet in March 2-6, June 08-12, before and after the General Conference on September 7-11 and September 21 and from November 16-20, when it will include the technical assistance and cooperation committee (TACC).
