Ukrainian engineers and construction workers are carrying out temporary repairs of the Chornobyl site’s New Safe Confinement (NSC) that was severely damaged in a drone attack earlier this year, Director General Rafael Mariano Grossi of the International Atomic Energy Agency (IAEA) said today.

The drone strike on 14 February pierced a big hole through the roof of the large confinement structure built to prevent any radioactive release from the reactor destroyed in the 1986 accident and protect it from external hazards. It took several weeks to completely extinguish the fires and smouldering caused by this strike.

The IAEA team based at the Chornobyl plant in northern Ukraine visited the NSC in recent days to discuss ongoing efforts by the site to assess the building’s structural integrity following the attack almost three months ago and to observe repairs of the inner and outer cladding to prevent water ingress.

“Immediately after the drone strike Ukrainian emergency personnel rushed to contain and eventually put out the fires. The site is now focusing its efforts on assessing the full extent of the damage while also carrying out short-term repairs. It is clear that the confinement structure – constructed at huge expense and with major international support – suffered extensive damage,” Director General Grossi said.

The Director General reiterated, however, that there has not been any radioactive release as a result of the damage, and that the NSC is able to continue to perform its protective function.

At Ukraine’s Zaporizhzhya Nuclear Power Plant (ZNPP), the IAEA team has continued to hear explosions in the distance every day over the past week, a constant reminder of the potential dangers facing nuclear safety and security.

The IAEA team has conducted walkdowns across the site to observe site activities, visiting all Emergency Control Rooms of the six reactors, the safety systems of unit 4, and the two fresh fuel storage facilities.

At Ukraine’s three operating nuclear power plants (NPPs) – Khmelnytskyy, Rivne and South Ukraine – three of their total of nine reactors remained shutdown for maintenance and refuelling outages.  

At the South Ukraine NPP, the IAEA team reported about many air raid alarms over the past week. The team was informed by the site that six drones were detected at a distance of 1.5 km from the plant in the night of 25 April, coinciding with the sound of military activity that appeared to be coming from an attempt to shoot them down.

At the Khmelnytskyy NPP, the IAEA team members were required to shelter on the morning of 30 April due to an air raid alert.

As part of the IAEA’s medical assistance programme for Ukraine, 200 boxes of influenza medication were delivered to the National Research Centre for Radiation Medicine of the National Academy of Medical Sciences of Ukraine (NRCRM), funded by Japan.

For the second year in a row, the IAEA has been invited to collaborate with the G20 on work related to nuclear power. The cooperation with the G20 (Group of Twenty) resumed under the presidency of South Africa at meetings this week in Cape Town, kicking off with a side event hosted by the IAEA and South Africa on the role of nuclear energy in clean energy transitions, as one of the technology dialogues that the presidency is featuring throughout the yearlong process.

Building on its first-ever collaboration on nuclear power with the G20 in 2024 under the presidency of Brazil, the IAEA engagement this year will include publications tailored to inform the group on topics such as the prospects for nuclear power in Africa and repurposing coal-fired plants with nuclear power such as small modular reactors (SMRs),  as well as participation in the G20 Ministerial Meeting on Energy, set for 23-26 September.

“At a time when energy access and security of supply are issues of global concern, the role of nuclear energy in low carbon, resilient and affordable energy systems remains indispensable,” IAEA Director General Rafael Mariano Grossi said. “Continuing the work that the IAEA began under the presidency of Brazil, we are now looking forward to working with South Africa.”

The first African country to assume the G20 presidency, South Africa is pursuing an Africa-wide approach emphasizing energy security, a just and inclusive clean energy transition and regional energy cooperation. While South Africa remains the only country on the continent to have nuclear power and aims to expand its programme, several African countries have expressed interest in or are embarking its introduction. Egypt is building four large reactors, and other countries such as Ghana and Kenya are working with the IAEA to establish the necessary infrastructure for a nuclear power programme, with a particular interest in SMRs.

The side event opened with special remarks from Kgosientsho Ramokgopa, Minister of Electricity and Energy of South Africa. Delegates from the G20 Energy Transitions Working Group (ETWG) attended the event, which discussed the state of nuclear power in South Africa as well as the IAEA’s outlook on nuclear power and a description of the upcoming publications that the IAEA will publish as part of its G20 collaboration this year. A session on nuclear power project financing issues followed, with panellists from the IAEA, the International Energy Agency, France and South Africa discussing ways to unlock financing for nuclear power projects and pave the way for faster deployment.

“In the wake of the world aiming to reach net zero by 2050, there has been a return to realism where it is globally accepted that nuclear technology has a huge role to play in the energy mix as a key source to ensure countries achieve their energy security, energy sovereignty, and energy justice in the transition,” said Minster Ramokgopa. “The expansion of the nuclear programme gives South Africa energy security and sovereignty that enables the country to move its economy into a digital era, engage in new research frontiers and take its rightful place amongst leading nations.”

During the event, delegates from G20 members and invited countries delivered remarks from the floor and offered their national perspectives.

“Italy is working to relaunch the use of sustainable nuclear energy, in its net zero emissions path by 2050. We have created the National Platform for Sustainable Nuclear involving R&D centres and industrial capabilities and nowadays our Government is strongly committed to work on enabling a favourable legislative and regulatory framework aimed at promoting the use of safe and innovative nuclear at the national level, including small modular reactors and Generation IV advanced modular reactors,” said Alberto Pela, Head of Delegation and Senior Advisor on International activities at the Department of Energy of the Ministry of Environment and Energy Security of Italy.

The United Arab Emirates, an invited country, recently began operating four large nuclear power reactors.

“In the UAE, nuclear energy is more than a power source — it’s a cornerstone of our clean, safe, and sustainable energy future,” said Nawal Yousif Alhanaee, Director of the Future Energy Department at the UAE’s Ministry of Energy and Infrastructure. “With the Barakah Nuclear Energy Plant meeting up to 25 per cent of our electricity needs, we affirm our commitment to a carbon-free tomorrow powered by peaceful and reliable nuclear technology.”

The IAEA training also helps to harmonize data collection methods, so that data collected in the Galapagos is comparable to data gathered by monitoring programs around the world which helps to develop policy measures.   

“Worldwide, NUTEC Plastics partners and members of its Global Marine Monitoring Network are working in a wide variety of marine and coastal environments, so monitoring protocols will vary accordingly,” said Carlos Alonso-Hernandez, an IAEA research scientist and technical officer for NUTEC. “Harmonizing these protocols enables us to compare data globally, which gives countries the whole picture of microplastic pollution.”

“To achieve sustainable development and prosperity, the world needs an abundance of clean, reliable and sustainable energy,” Director General Grossi said.

With World Bank President Banga, Director General Grossi shared the IAEA’s perspective on nuclear energy and said the IAEA stands ready, upon request, to provide technical support to MDBs, particularly on nuclear infrastructure development including nuclear safety, security and safeguards.

The World Bank and other MDBs currently do not contribute financing to nuclear power new build projects, although some MDBs have provided lending for upgrades to existing nuclear power reactors or their decommissioning.

Director General Grossi said that financing nuclear power would better align MDBs with the “new global consensus” forged at COP28 in Dubai, where the world called for accelerating the deployment of nuclear power along with other zero emission energy technologies to achieve deep and rapid decarbonization.

In addition, the Director General spoke at two high-profile think-tank events organised by the Council on Foreign Relations and Carnegie Endowment for International Peace respectively, answering questions on Iran’s nuclear programme, North Korea’s nuclear activities, the renewed worldwide momentum for nuclear energy and other current issues.

Update 288 – IAEA Director General Statement on Situation in Ukraine

IAEA experts based at Ukraine’s Zaporizhzhya Nuclear Power Plant (ZNPP) were required to stay indoors yesterday morning after hearing loud bursts of gunfire from near the main administrative building where their office is located, Director General Rafael Mariano Grossi said.

The ZNPP informed the IAEA staff members that a nearby “drone threat” had made it necessary to postpone the team’s planned activities at the site, the latest incident highlighting persistent risks to nuclear safety and security during the military conflict.

The IAEA team remained in the administrative building after the plant-wide shelter order was announced.

In addition, the IAEA team has continued to hear explosions and gunfire at varying distances from the plant almost every day during the past week.

“What was once virtually unimaginable – evidence of military action in the vicinity of a major nuclear facility – has become a near daily occurrence and a regular part of life at Europe’s largest nuclear power plant. From a nuclear safety perspective, this is clearly not a sustainable situation. The IAEA remains committed to doing everything we can to prevent a nuclear accident during this tragic war,” Director General Grossi said.

Despite the regular sound of military activities in the area, the IAEA experts have continued to conduct walkdowns across the plant to monitor and assess nuclear safety and security. In recent days, for example, the team visited the ZNPP’s low-level solid radioactive waste storage facility, as well as other installations at the sprawling industrial site.

In meetings earlier this week, the experts discussed with the ZNPP the staffing situation at the plant as well as various maintenance activities, including to some of the safety systems.

At Ukraine’s other nuclear power plants (NPPs) – Khmelnytskyy, Rivne and South Ukraine – IAEA teams have also continued to monitor nuclear safety and security. All three plants are still producing electricity, although some units are in planned outage while others occasionally have to reduce output.

At the Khmelnytskyy NPP, for example, one reactor remained in outage for maintenance and refuelling, while the power production of the second unit was reduced at the request of the grid operator for 36 hours earlier this week. At the Rivne NPP, a second unit was placed in outage for maintenance and refuelling, while the power production of a third was reduced at the request of the grid operator for a few days this week.

The South Ukraine NPP also experienced power variations this week. The IAEA team at the plant was informed that seven drones were detected 2 km east of the site on 17 April, also a frequent occurrence during the conflict. Likewise, the teams – particularly at the Chornobyl site and the South Ukraine NPP – have continued to hear air raid alarms most days.

The IAEA teams at the Rivne, South Ukraine and Chornobyl sites all rotated over the past week.

As part of the IAEA’s technical nuclear safety and security assistance to Ukraine, the Hydrometeorological Centre and the Hydrometeorological organizations of the State Emergency Services of Ukraine received radiation detection and measurement equipment, and associated reference sources procured with funding from Austria and the United States. It was the 131st delivery organized by the IAEA since the start of the conflict.

The IAEA team based at Ukraine’s Zaporizhzhya Nuclear Power Plant (ZNPP) today examined the area near the plant’s training centre where a drone was reportedly shot down and crashed, once again underlining potential risks to nuclear safety during the military conflict, Director General Rafael Mariano Grossi said.

The IAEA requested access to the purported crash site after receiving information from the ZNPP that the incident had occurred on Wednesday afternoon, local time. The crash sparked a fire that ignited surrounding vegetation but caused no casualties nor structural damage to the training centre itself, which is located just outside the site perimeter, the ZNPP added.

At the impact site, the IAEA team observed white ash covering a small area and was shown what the ZNPP identified as the remains of a drone, including four small electric motors still lying on the ground. Plastic fragments, apparently parts of the body of a drone, were also visible.

The latest incident came a few months after a similar report about a drone incident near the same training centre for the ZNPP. In February 2025, a drone attack caused significant damage to the New Safe Confinement structure at the Chornobyl site in northern Ukraine. There are also frequent reports of drones detected near Ukraine’s other nuclear sites.

“Any attempt to target a nuclear site with drones can have serious consequences. Whilst offensive drones may be relatively small, they can have serious implications for nuclear safety, for example by causing fires or structural damage. I continue to call for utmost military restraint near all nuclear facilities,” Director General Grossi said.

Frequent air raid alarms, the regular sound of explosions nearby and the presence of drones are continuing to highlight the dangers facing Ukraine’s main nuclear sites during the military conflict, Director General Rafael Mariano Grossi of the International Atomic Energy Agency (IAEA) said today.

“The nuclear safety and security situation in Ukraine remains precarious. This is very clear from the daily reports of our teams on the ground. Military activities are still taking place in the vicinity of nuclear sites, putting their safety at constant risk. Our work to help prevent a nuclear accident is far from over,” Director General Grossi said.

The IAEA continues to monitor and assess nuclear safety and security at Ukraine’s five main nuclear facilities and deliver essential equipment and other technical assistance, including medical support.

At the Zaporizhzhya Nuclear Power Plant (ZNPP) over the past week, the IAEA team based at the site has heard explosions at varying distances almost every day, as well as occasional bursts of gunfire.

As part of regular walkdowns across the site, the team visited the turbine halls of two reactor units, where they were again denied access to the western parts of the halls. The team also visited the site’s water treatment facility where they confirmed the arrangements for the treatment of wastewater and observed the testing of an emergency diesel generator.

At the South Ukraine NPP, the IAEA team was informed that five drones were detected 2 km west of the site during the night of 11-12 April. From their residence, the team observed the drones and heard gunfire apparently aimed at repelling them.

At the Chornobyl site, the IAEA team visited the New Safe Confinement and received an update on its status following the mid-February drone attack that punched a hole in the structure. Radiation levels remained normal for the area and there had been no release of radioactive substances beyond the established limits.

Air raid alarms were heard on most days over the past week at these two sites, the IAEA teams reported.

Over the past week, the IAEA has organised five additional deliveries of equipment as part of its efforts to help ensure nuclear safety and security, bringing the total to 130 since the start of the conflict.

The Rivne NPP received two static test benches that had been refurbished and modernized in Germany, with funding from Norway. Plant staff also received training on the newly automated system. The benches are used to test the plant’s hydraulic shock absorbers, which reduce vibrations in coolant pumps, steam generators and other equipment essential for nuclear safety.

Other types of equipment were delivered to Chornobyl, the Centralized Dry Spent Nuclear Fuel Storage Facility and State Specialized Enterprise “Radon Association”, which manages radioactive waste. These deliveries were funded by the European Union, Denmark and Sweden. The Khmelnytskyy NPP received medical equipment supported with funding from Norway.

IAEA and International Experts Sample Treated Water within Fukushima Daiichi Nuclear Power Station Prior to its Release

The International Atomic Energy Agency (IAEA), along with experts from the People’s Republic of China, the Republic of Korea, the Russian Federation, and Switzerland, collected samples today of ALPS treated water that had been diluted with seawater ahead of its discharge into the sea at Japan’s Fukushima Daiichi Nuclear Power Station (FDNPS).

The activity is the latest mission carried out under the additional measures which focus on expanding international participation and transparency, allowing hands-on independent measurements of the concentration level of the ALPS treated water which TEPCO – operator of the FDNPS – began discharging in August 2023. In September 2024, the IAEA agreed with Japan to implement additional measures. Through additional measures, third parties can independently verify that water discharge levels are, and will continue to be, in strict compliance and consistent with international safety standards.

Today’s sampling was the first mission of the additional measures under the IAEA framework to sample the diluted water from the discharge facilities at the plant. It follows a mission in February when IAEA Director General Grossi joined the activities with experts from China, the Republic of Korea and Switzerland to collect seawater samples from a boat in the vicinity of FDNPS. It also builds on the first practical steps of the additional measures carried out in October last year when international experts conducted seawater sampling.

The experts from the China Institute for Radiation Protection, the Korean Institute for Nuclear Safety, the Institute of Natural Monopolies Research in Russia, and the Spiez Laboratory in Switzerland collected samples from the discharge vertical shaft and seawater pipe header where ALPS treated water is diluted with seawater before being discharged through a  one-kilometre-long tunnel into the sea. The samples were taken from the 12th batch of ALPS treated water to be discharged. Last week, the IAEA confirmed that the tritium level in the 12th batch was far below Japan’s operational limit.

The samples will be analysed by the IAEA laboratory, by laboratories in Japan and in the participating laboratories from China, Korea, Russia and Switzerland, all members of the IAEA’s Analytical Laboratories for the Measurement of Environmental Radioactivity (ALMERA) network, which were selected for their high level of expertise and analytical proficiency.

China is making remarkable progress in nuclear energy and is a strong supporter of the IAEA’s mission to ensure that nuclear technology serves peace and development, IAEA Director General Rafael Mariano Grossi said while meeting China’s Foreign Minister Wang Yi in Beijing. They also exchanged on China’s commitment to multilateralism and non-proliferation.

During a week-long visit to China, Mr Grossi has met with several high-level officials, signed agreements and visited nuclear and energy facilities and institutions as well as the prestigious Peking University.

Nuclear Energy and SMRs

China operates 58 civil nuclear reactors and has almost 30 new builds in progress. This represents nearly half of all power reactors currently under construction worldwide.

Mr Grossi began his visit at the Hainan Changjiang Nuclear Power Plant, which has some of the country’s most advanced nuclear technologies. This includes a high-pressurized water nuclear reactor and a commercial small modular reactor (SMR).

Later, Mr Grossi addressed nuclear power plant personnel and students from the region at a special event where a SMR user requirements document was presented. The document outlines the specific needs and expectations for SMRs, covering design, safety, licensing, and other relevant aspects.

“China is making strong progress in SMR deployment,” said Mr Grossi. “This event marks an important step toward safe and effective implementation.”

Meeting the new Chairman of the China Atomic Energy Authority (CAEA), Shan Zhongde, Mr Grossi added,  “China plays a leading role across the peaceful uses of nuclear science and technology — from power to medicine, food and more.”

Artificial Intelligence

Mr Grossi also discussed the use of artificial intelligence (AI) and innovative technologies with the President from China National Nuclear Corporation (CNNC), Shen Yanfeng, signing an arrangement with China Nuclear Power Engineering to apply AI and other innovative technology to boost performance at nuclear facilities.

Nuclear and the Energy Transition

Mr Grossi spoke with Liu Zhenmin, China’s Special Envoy for Climate Change about how China is investing in nuclear to help power its growing economy and decarbonize.

In 2020, President Xi Jinping pledged to start cutting CO2 emissions by 2030 and that China would become a carbon-neutral country by 2060.

During a visit to China’s State Power Investment Corporation (SPIC) on Friday, Mr Grossi also exchanged with SPIC Chairman Liu Mingsheng on clean, smart and innovative energy generation. SPIC owns a number of nuclear power plants under construction and in operation.

On the last day of his visit, Mr Grossi visited China Huaneng Group (CHNG) in Beijing, one of the largest state-owned electricity companies in China. CHNG has participated in projects such as the Shidao Bay and Hainan Changjiang Nuclear Power Plants.

“Huaneng Group is central to China’s energy transition — showcasing the value of a diversified low-carbon energy mix including nuclear,” he said.

Nuclear Safety and Security

As China expands its nuclear energy programme, the country continues to strengthen its cooperation with the IAEA in nuclear safety. On Wednesday, Mr Grossi met with Dong Baotong, the Administrator of the National Nuclear Safety Administration of China and agreed on increased cooperation between the IAEA and China in this area.

Energy, Health and Atoms4Food

China is supporting the IAEA’s initiatives to use nuclear techniques and technologies to help boost energy security, enhance global health and grow better food.

Mr Grossi met with the Director of China International Development Cooperation Agency (CIDCA) Luo Zhaohui to discuss these priorities.

While at CAEA, Mr Grossi signed a new Country Programme Framework with China and an arrangement with CAEA to strengthen education and training in the safe and peaceful use of nuclear technology via a Chinese university consortium at the authority.

He also discussed education during an exchange with China’s Education Vice Minister Xu Qingsen.

“The IAEA works closely works closely with Chinese universities — and we’ll do more — to train the next generation of professionals,” he said. Mr Grossi expressed his gratitude to China for its support to the IAEA Marie Skłodowska-Curie Fellowship Programme, which provides scholarships and internships to women master’s students studying STEM subjects.
