Update on Developments in Iran (7)

Source: International Atomic Energy Agency (IAEA) –

Radiation levels in the Gulf region remain normal following the 12-day conflict that severely damaged several nuclear facilities in Iran, Director General Rafael Mariano Grossi of the International Atomic Energy Agency (IAEA) said today.

Citing regional data reported regularly to the IAEA through the International Radiation Monitoring System (IRMIS), Director General Grossi noted that this 48-nation network would have detected an important radioactive release from any damaged nuclear power reactor.

“From a nuclear safety perspective, Iran’s Bushehr Nuclear Power Plant and the Tehran Research Reactor represented our main concern as any strike affecting those facilities – including their off-site power lines – could have caused a radiological accident with potential consequences in Iran as well as beyond its borders in the case of the Bushehr plant. It did not happen, and the worst nuclear safety scenario was thereby avoided,” Director General Grossi said.

Stressing again that nuclear facilities should never be attacked, he reiterated the IAEA’s current assessment – based on information received from Iran’s Nuclear Regulatory Authority – that this month’s Israeli and U.S. strikes on Iranian nuclear sites would have caused localized radioactive releases inside the impacted facilities and localized toxic effects, but there has been no report of increased off-site radiation levels.

The Director General also emphasised the need for IAEA inspectors to continue their verification activities in Iran, as required under its Comprehensive Safeguards Agreement (CSA) with the Agency.

Update 298 – IAEA Director General Statement on Situation in Ukraine

Source: International Atomic Energy Agency (IAEA) –

Ukraine’s Zaporizhzhya Nuclear Power Plant (ZNPP) remains reliant on one single off-site power line to receive the external electricity it needs to cool its six reactors and their spent fuel, some seven weeks after it lost the connection to its last back-up power line, Director General Rafael Mariano Grossi of the International Atomic Energy Agency (IAEA) said today.

“The extremely fragile external power situation as well as challenges related to the availability of cooling water after the Kakhovka dam was destroyed two years ago underline the fact that nuclear safety remains highly precarious at the Zaporizhzhya Nuclear Power Plant. There are many important issues that must be addressed before it will be feasible to restart the plant,” Director General Grossi said.

The 330 kilovolt (kV) power line was disconnected on 7 May due to military activities some distance away from the ZNPP, leaving Europe’s largest nuclear power plant (NPP) dependent on one 750 kV line. Before the conflict, it had access to ten off-site power lines. Its six reactors have been in cold shutdown since 2024, but still require cooling water for their reactor cores.

Almost every day over the past week, the IAEA team based at the ZNPP has continued to hear explosions at various distances away from the site, a constant reminder of the close proximity to the frontline of the conflict.

The IAEA team has continued to conduct walkdowns across the site as part of the Agency’s mission to monitor and assess nuclear safety and security there.

Elsewhere in Ukraine, the IAEA teams at Ukraine’s three operating NPPs – Khmelnytskyy, Rivne and the South Ukraine – and the Chornobyl site reported hearing air-raid alarms over the past week. The teams at the Chornobyl site and the Rivne and South Ukraine NPPs have all rotated in recent days. Early on 21 June, the IAEA team at the South Ukraine NPP observed a drone around one kilometre from their hotel.

Two new deliveries of equipment have taken place under the IAEA’s comprehensive assistance programme for nuclear safety and security in Ukraine, bringing the total number of such shipments to 142 since the start of the armed conflict.

The State Enterprise Ukrainian Geological Company received portable radiation detection and monitoring devices within the framework of the IAEA Support and Assistance Mission to the Kherson Oblast (ISAMKO) programme in response to flooding caused by the destruction of the Kakhovka dam in mid-2023. The two deliveries were supported with funds from Japan.

The World Bank Group and the International Atomic Energy Agency (IAEA) sealed an agreement today to work together to support the safe, secure and responsible use of nuclear energy in developing countries. The partnership agreement, signed by World Bank Group President Ajay Banga and IAEA Director General Rafael Mariano Grossi, formalizes multiple engagements between the two institutions over the last year, and marks the World Bank Group’s first concrete step to reengage with nuclear power in decades.

The agreement also reflects a new, broader approach by the World Bank Group to electrification—one that prioritizes accessibility, affordability, and reliability, while managing emissions responsibly. With electricity demand in developing countries expected to more than double by 2035, this approach aims to help countries deliver the energy people need by enabling pathways that best fit their national context, including development objectives and Nationally Determined Contributions.

Nuclear energy provides continuous baseload power, enhancing grid stability and resilience. Reliable baseload electricity is essential for job-generating sectors such as infrastructure, agribusiness, healthcare, tourism, and manufacturing. Nuclear power is also a source of high-skilled employment and stimulates investment across the broader economy. In addition, it can adjust to changes in electricity demand and support frequency regulation, enabling greater integration of variable renewable energy sources.

“Jobs need electricity. So do factories, hospitals, schools, and water systems. And as demand surges—with AI and development alike—we must help countries deliver reliable, affordable power. That’s why we’re embracing nuclear energy as part of the solution—and reembracing it as part of the mix the World Bank Group can offer developing countries to achieve their ambitions. Importantly, nuclear delivers baseload power, which is essential to building modern economies,” said World Bank Group President Ajay Banga. “Our partnership with the IAEA marks an important step, and I’m grateful to Rafael for his personal commitment and leadership in making this possible. Together, we’ll deepen our expertise, support countries that choose nuclear, and ensure that safety, security, and sustainability guide every step forward.”

“Today’s agreement is a milestone and the result of a year of joint work since President Ajay Banga kindly invited me to the World Bank Group Executive Board in Washington in June of last year,” IAEA Director General Grossi said. “This landmark partnership, yet another sign of the world’s return to realism on nuclear power, opens the door for other multilateral development banks and private investors to consider nuclear as a viable tool for energy security and sustainable prosperity. Together, we can help more people build a better future.”

Under the memorandum of understanding signed today, the IAEA will work with the World Bank Group in three key areas:

  • Build knowledge related to the nuclear field: Expand the World Bank Group’s understanding of nuclear safety, security, safeguards, energy planning, new technologies, fuel cycles, reactor lifecycles, and waste management.
  • Extend the lifespan of existing nuclear power plants: Support developing countries in safely extending the life of existing nuclear reactors-one of the most cost-effective sources of low-carbon power-as many global reactors near the end of their original 40-year design life.
  • Advance SMRs: Accelerate the development of small modular reactors (SMRs), which offer flexible deployment, lower upfront costs, and potential for wide adoption in developing economies.

Thirty-one countries currently operate nuclear power plants, which combined produce about 9% of the world’s electricity, amounting to almost a quarter of all low-carbon power globally. More than 30 other countries, most of them in the developing world, are considering or already embarking on the introduction of nuclear power and are working with the IAEA to develop the necessary infrastructure to do so safely, securely and sustainably.

“SMRs have great potential to cleanly and reliably power progress and fight poverty, but financing remains a roadblock,” Director General Grossi said. “Today’s agreement is a crucial first step to clearing that path.”

The International Atomic Energy Agency (IAEA), in collaboration with over 75 countries and 10 international organizations, successfully concluded a 36-hour simulation that tested global readiness and response mechanisms to a severe nuclear emergency scenario at Romania’s Cernavodă Nuclear Power Plant. The ConvEx-3 (2025) exercise began on 24 June and concluded today, 25 June, at about 17:45 CEST.

Such exercises are held every three to five years and are based on simulated events hosted by IAEA Member States.

The exercise simulated a significant release of radioactive material, prompting participating nations and organizations to engage in real-time decision-making, information exchange, public communication and coordination of protective actions, including medical response and cross-border logistics.

“The ConvEx-3 (2025) demonstrated the strength of international cooperation in nuclear emergency preparedness,” said Carlos Torres Vidal, Director of the IAEA’s Incident and Emergency Centre. “By working together in realistic scenarios, we enhance our collective ability to protect people and the environment.”

Key innovations in this year’s exercise included:

  • Enhanced regional collaboration: Recognizing the transboundary impact of severe nuclear accidents, neighbouring countries Bulgaria and the Republic of Moldova coordinated protective measures to ensure harmonized responses across borders.
  • Integration of nuclear security scenarios: The simulation incorporated physical protection challenges and cyber security threats, reflecting evolving risks.
  • Advanced crisis communication testing: An expanded social media simulator was utilized to assess and improve public information strategies.
  • Deployment of international assistance missions: Expert teams from Bulgaria, Canada, France, Lithuania, Moldova, Sweden and the United States of America conducted joint operations, including aerial and land-based radiation monitoring, under the IAEA’s Response and Assistance Network (RANET).

The exercise emphasized the importance of timely information sharing, accurate assessment and prognosis, and effective public communication during nuclear emergencies.

ConvEx-3 exercises are conducted every three to five years to evaluate and strengthen the emergency response frameworks established under the Convention on Early Notification of a Nuclear Accident and the Convention on Assistance in the Case of a Nuclear Accident or Radiological Emergency.

In the coming weeks, the IAEA will compile feedback from all participants to identify best practices and areas for improvement, contributing to the continuous enhancement of global nuclear emergency preparedness. The final report will guide preparations for the upcoming International Conference on Nuclear and Radiological Emergencies (EPR 2025) to be held this December in Riyadh, Saudi Arabia.

The International Atomic Energy Agency (IAEA) conducted its first-ever management systems advisory service in the Kingdom of Saudi Arabia from 19 to 22 May 2025.

The IAEA Management Systems Advisory Service (IMSAS) was established to support newcomer countries in developing robust and effective nuclear infrastructure, in response to findings from the Agency’s Integrated Nuclear Infrastructure Review (INIR) missions that highlighted inconsistencies in the implementation of management systems among countries embarking on new nuclear power programmes.

As part of the IAEA’s broader commitment to support countries in introducing nuclear power in their energy mix, IMSAS helps nuclear organizations develop and maintain management systems appropriate to the current phase of the nuclear power programme. A management system is a set of interrelated or interacting elements — including organizational structure, responsibilities, resources, and processes — established to achieve organizational objectives in an efficient and effective manner.

Saudi Arabia is embarking on a nuclear power programme as part of its strategy to transition towards a diversified energy sector and building national capabilities in advanced energy technologies, all as part of its Vision 2030. In support of this plan, Saudi Arabia is following the IAEA’s Milestones Approach and actively cooperates with the IAEA through a coordinated Integrated Workplan to support its nuclear infrastructure development.

In November 2024, Duwayhin Nuclear Energy Company (DNEC), which is designated as the owner/operator for the first nuclear power plant, requested the IAEA to conduct the IMSAS mission to review whether the current management system in DNEC is appropriate and adequate to support its current and planned activities.

During its review, the IMSAS team – comprised of four external experts from Hungary, Sweden, the United Kingdom and the United States of America, as well as three IAEA staff members – reviewed documentation and conducted technical discussions with the DNEC in Riyadh.

“The IMSAS team found that DNEC has a well-developed management system that effectively supports the organization in carrying out its current and future activities. We commend DNEC on the efforts undertaken to date to develop its management system, which will help support the safe and effective implementation Saudi Arabia’s nuclear power programme,” said Liliya Dulinets, Section Head of the IAEA Nuclear Infrastructure Development Section.

In its draft final report, issued at the closing session, the mission team identified four good practices by DNEC. These included the development of its management system using a structured, project-based approach that ensures effective planning and coordination; the clear documentation of governance and management frameworks, which provides staff with a solid understanding of roles and responsibilities; and the transition to a fully electronic management system to enhance accessibility and usability.

Two recommendations and four suggestions were also noted. These included opportunities for improvement related to enhancing the consistency of the management system documentation, formalizing the approach to process development, and elevating the level of ownership of the management system within the organization.

“Our objective in requesting the mission was to have the IAEA conduct a cold-eye review of how we manage our day-to-day operations, particularly our management system,” said Khalid Al Gazlan, DNEC CEO. “The results of the mission were excellent, and the recommendations and suggestions provided will greatly support our continuous improvement efforts. We remain committed to cooperating with the IAEA through the Integrated Work Plan across all phases of our project, to ensure the establishment of a competent Owner-Operator; we thank the IAEA and the IMSAS team for this constructive and productive mission. This mission was a testament that the Kingdom is moving confidently towards building a sustainable civil nuclear program, supported by national competencies and strong international partnership.”

The final mission report will be provided to DNEC within three months.

About IMSAS

IMSAS was established to support the review of management systems in countries embarking on new nuclear power programmes. It provides a structured approach for the self-assessment of the management systems of the regulatory body and owner/operator organization, as well as an independent review conducted by IAEA and international experts.

IMSAS missions help organizations develop and maintain effective management systems consistent with the current phase of the nuclear power programme. It assists these organizations in aligning their management systems with IAEA standards and international good practices to support the implementation of current and planned activities. Additionally, IMSAS enables the identification of strengths and weaknesses through a combination of self-assessment and independent review, providing recommendations for improvement and highlighting good practices.

The IAEA offers its Member States a wide array of review services. For the introduction of nuclear power, the Agency’s peer review service include, for example, the Integrated Nuclear Infrastructure Review (INIR) and the Stakeholder Engagement Advisory Service for Nuclear Power Programmes (SEAS).

Update on Developments in Iran (6)

Source: International Atomic Energy Agency (IAEA) –

Director General Rafael Mariano Grossi has welcomed today’s announcements regarding the situation in Iran and stressed the need for a resumption of the IAEA’s indispensable safeguards verification work in the country following a 12-day military conflict that severely damaged several of its nuclear sites.

In a letter to Iranian Foreign Minister Dr Abbas Araghchi, Director General Grossi also proposed that they meet soon.

“Resuming cooperation with the IAEA is key to a successful diplomatic agreement to finally resolve the dispute over Iran’s nuclear activities. I’ve written to Foreign Minister Araghchi stressing the importance of us working together and proposing to meet soon,” he said.

IAEA inspectors have remained in Iran throughout the conflict and are ready to start working as soon as possible, going back to the country’s nuclear sites and verifying the inventories of nuclear material – including more than 400 kg of uranium enriched to 60% – which they last verified a few days before the Israeli air strikes began on 13 June.

Even though the conflict interrupted safeguards inspections in the country, the IAEA has been closely monitoring the impact of the military strikes on Iranian nuclear sites at Arak, Esfahan, Fordow and Natanz as well as the possible consequences for human health and the environment, based on relevant information received from Iran’s Nuclear Regulatory Authority.

“As I have repeatedly stated – before and during the conflict – nuclear facilities should never be attacked due to the very real risk of a serious radiological accident,” Director General Grossi said.

“During these attacks, we have seen extensive damage at several nuclear sites in Iran, including its uranium conversion and enrichment facilities. Our assessment is that there has been some localized radioactive as well as chemical release inside the affected facilities that contained nuclear material – mainly uranium enriched to varying degrees – but there has been no report of increased off-site radiation levels,” he said.  

Still, the IAEA is aware of concerns in the region regarding any radiological consequences as a result of the strikes on nuclear facilities.

“Based on the data available to us, the IAEA can provide assurances that there has been no radiological impact to the population and the environment in neighbouring countries. Crucially in terms of nuclear safety, Iran’s research and power reactors were not targeted,” Director General Grossi said.

In addition to the detailed assessment that Director General Grossi provided to the IAEA Board of Governors on Monday, the IAEA has identified additional impact points at nuclear sites at Fordow and Natanz as a result of strikes carried out before today’s announcements on the situation in Iran.

Regarding the additional strikes to Fordow that were reported early on Monday – after the U.S. bombing of the facility early on Sunday – the IAEA assesses that access roads close to the underground facility and one of its entrances were hit.

At Natanz, the IAEA has identified two impact holes from the U.S. strikes above the underground halls that had been used for enrichment as well as for storage. Based on its knowledge of what these halls contained, the IAEA assesses that this strike may have caused localized contamination and chemical hazards.

Advancing Cancer Care in Niger

Source: International Atomic Energy Agency (IAEA) –

In May 2025, IAEA Director General Rafael Mariano Grossi visited Niger’s only radiotherapy centre, CNLC, in Niamey, accompanied by Minister of Public Health Garba Hakimi, Shaukat Abdulrazak, Director of the IAEA’s Division for Africa, and other senior government officials.

Cancer is a growing healthcare challenge in Niger, with over 11 000 new cases and more than 8800 cancer related deaths reported in 2022. Radiotherapy — a treatment needed in nearly half of all cancer cases — remains in short supply in the country, and even those who can afford access to it are let down by out-of-date equipment.  

Through its Rays of Hope initiative, the IAEA is supporting efforts to strengthen radiotherapy services in Niger, aiming to expand access to cancer care where it is needed most. 

Through the initiative, the IAEA supported Niger in establishing a new cancer treatment facility with state-of-the-art equipment including medical linear accelerator (LINAC), a computed tomography-simulator, an advanced treatment planning system, dosimetry equipment and related accessories.  

The new equipment will help expand services for radiotherapy at Niger’s only public radiotherapy centre, which serves a population of 24 million people. Medical professionals will be able to treat tumours more accurately through the country’s new equipment, while sparing normal tissues and critical organs. More Nigerien cancer patients can also be treated locally without having to travel abroad for care. 

“The presence of this machinery in our country will significantly enhance the quality of life for the people of Niger, as it will lead to a considerable decrease in treatment costs and medical evacuations”, said Abdourahamane Tchiani President of Niger.

The International Atomic Energy Agency (IAEA) and Romania will launch tomorrow, 24 June, the world’s largest and most complex international nuclear emergency exercise, simulating a severe accident at Romania’s Cernavodă Nuclear Power Plant.

Such exercises are held every three to five years and are based on simulated events hosted by IAEA Member States.

Over two days, more than 75 countries and 10 international organizations will take part in the ConvEx-3 (2025)—a full-scale exercise designed to test global readiness for a nuclear or radiological emergency with cross-border consequences. Participation will occur both on-site in Romania and remotely from other countries.

As nuclear use expands globally, its success hinges on strong safety standards and constant vigilance, said IAEA Director General Rafael Mariano Grossi. “This exercise is a clear demonstration of the international community’s commitment to protect people and the environment by working together, across borders and systems, when every minute counts.”

“Hosting ConvEx-3 is both a responsibility and an opportunity for Romania,” said Cantemir Ciurea-Ercău, President, National Commission for Nuclear Activities Control (CNCAN). “Two decades after we hosted the first ConvEx-3, we are proud to again contribute to strengthening global nuclear emergency preparedness. In today’s interconnected world, effective preparedness must transcend borders—this exercise reflects our shared commitment to safety, cooperation and transparency.”

Romania, bordering five countries, last hosted such an exercise in 2005. Cernavodă is the country’s only nuclear power plant, situated roughly 160 kilometres east of Bucharest, close to the Black Sea. During the 36-hour exercise, participants will simulate real-time decisions, emergency communications and international coordination under the Convention on Early Notification of a Nuclear Accident (Early Notification Convention) and the Convention on Assistance in the Case of a Nuclear Accident or Radiological Emergency (Assistance Convention). These will include protective actions such as simulated evacuation and iodine distribution, public outreach and communication, medical response coordination, and the management of food and trade restrictions based on radiological assessments.

The IAEA will activate its Incident and Emergency Centre (IEC) and test critical tools like the Unified System for Information Exchange (USIE), a secure platform for designated contact points from IAEA Member States, and the International Radiation Monitoring System (IRMIS) platform. Member States will also activate their national emergency centres, request or offer assistance, share monitoring data, and coordinate cross-border protective actions and messaging to their populations.

The ConvEx-3 (2025) was developed by SNN Nuclearelectrica and CNCAN, with international coordination by the Inter-Agency Committee on Radiological and Nuclear Emergencies (IACRNE), which includes the World Health Organization, World Meteorological Organization, European Commission, Food and Agriculture Organization of the United Nations, INTERPOL and others.

About Convention Exercises

Convention Exercises, or ConvEx, are held to test the operational arrangements of the Early Notification Convention and the Assistance Convention.  The goal is to evaluate and further improve the international framework for emergency preparedness and response. ConvEx are prepared at three levels of complexity:

  • ConvEx-1 is designed to test emergency communication links with contact points in Member States that need to be available 24 hours a day, seven days a week, and to test the response times of these contact points.
  • ConvEx-2 is designed to test specific parts of the international framework for emergency preparedness and response, for example to rehearse the appropriate use of communication procedures; to practice procedures for international assistance; and to test the arrangements and tools used for assessment and prognosis in a nuclear or radiological emergency.
  • ConvEx-3 is a full-scale exercise designed to evaluate international emergency response arrangements and capabilities for a severe nuclear or radiological emergency over several days, regardless of its cause.

Photos from the ConvEx-3 will be made available here.

Update on Developments in Iran (5)

Source: International Atomic Energy Agency (IAEA) –

The International Atomic Energy Agency (IAEA) can confirm that the Iranian nuclear sites of Fordow, Natanz and Esfahan have been hit, following U.S. aerial attacks overnight, Director General Rafael Mariano Grossi said today.

Based on an analysis of the information available to it, the IAEA assessed that there has been extensive additional damage at the sprawling Esfahan site, which had already been struck several times by Israel since it began targeting Iran’s nuclear facilities on 13 June, Director General Grossi said.

The IAEA had previously reported that several buildings at the Esfahan complex were damaged, some of which may have contained nuclear material.

“The latest attacks early this morning damaged other buildings in Esfahan. In addition, we have established that entrances to underground tunnels at the site were impacted,” Director General Grossi said.

The extent of damage to the Fordow uranium enrichment facility – built deep inside a mountain in central Iran – was not immediately possible to assess in view of its underground location and the penetrating nature of the bombs used.

“It is clear that Fordow was also directly impacted, but the degree of damage inside the uranium enrichment halls can’t be determined with certainty,” Director General Grossi said.

Iran’s other enrichment site, Natanz, which has previously been extensively damaged, was again attacked during the strikes last night with ground-penetrating munitions.

The Director General said the IAEA has been informed by the Iranian regulatory authorities that there has been no increase in off-site radiation levels after the latest attacks on the three Iranian nuclear sites.

Director General Grossi stressed the paramount importance of the countries involved urgently embarking on a diplomatic path aimed at ending the hostilities.

This would also enable the IAEA to resume its crucial verification activities in Iran, including of its stockpile of more than 400 kg of highly enriched uranium, which Agency inspectors last verified a few days before the military conflict began.

“We need to try to go back to the negotiating table as soon as possible. We have to allow the IAEA inspectors to return. The IAEA is ready to play its indispensable role in this process. We have been talking to Iran, we have been talking to the United States. We have to work for peace,” Director General Grossi said.
