In brief
In Vienna on 10 November, the International Atomic Energy Agency launched its 15th Symposium on International Safeguards, gathering about 1,000 attendees from 100 countries. Spearheaded by Deputy Director General Massimo Aparo, the conference underscored the need for resilience and innovation in verification methods amid fast‑moving technology and shifting geopolitics, while highlighting new data acquisition tools and the first complete cycle of the COMPASS capacity‑building initiative.
The International Atomic Energy Agency opened its 15th Symposium on International Safeguards in Vienna on 10 November, drawing roughly 1,000 participants from more than 100 countries. The meeting aimed to examine how newer technologies and changing global dynamics affect the integrity of nuclear safety, management, and its potential climate benefit.
Massimo Aparo, the agency’s deputy director general and head of the Department of Safeguards, emphasized that the world’s operating environment is in flux, demanding greater resilience and innovation. “Our operating environment is undergoing significant changes that are testing our resilience and challenging us to be more innovative,” Aparo said, calling on policymakers, industry members, civil society, and safeguarding professionals to uphold a robust system.
At a time when atmospheric greenhouse‑gas concentrations are climbing, the agency framed the safety of nuclear energy as a key factor for reliable, low‑emission electricity. By improving safeguards, the IAEA hopes to make nuclear technology a more trusted contributor to the global shift away from fossil fuels.
The symposium showcased how technology is tightening oversight. In 2025 alone, the IAEA performed almost 3,000 in‑field verifications across 191 states, collected nearly 1,000 material samples, and maintained around 1,400 surveillance cameras. More than 2,800 commercial satellite images were analyzed, and the agency verified more than 24,000 material seals. These figures illustrate the scale of the monitoring apparatus that supports nuclear transparency.
Central to the workshop was the first regular cycle of COMPASS – the Comprehensive Capacity‑Building Initiative. The program, which finished its inaugural cohort this year, brings inspectors and technical staff together for specialized training, peer study, and practice in field activities. Aparo noted that the initiative has helped standardize inspection techniques worldwide and improves the ability of countries to maintain sound safety protocols.
Another significant theme was the collaboration between nuclear operators, regulators, and the IAEA to embed safeguards into early design phases of nuclear reactors. This proactive partnership seeks to lower the probability of misuse and streamline the approval process for new facilities, thereby reducing political friction and boosting confidence in a clean energy source.
Participants also examined how geopolitical tensions can affect safeguard operations. Rapid advances in nuclear technology, including small modular reactors and thorium fuel cycles, introduce new verification challenges. The IAEA’s approach involves integrating emerging sensors and analytical tools into inspection workflows, ensuring that safeguards keep pace with the technology’s evolution.
Throughout the day, experts highlighted how resilient safeguards guard against sabotage, proliferation, and accidental release, all of which could undermine the environmental benefits of nuclear power. By emphasizing shared responsibility, the agency stressed that the entire international community must commit to maintaining a trustworthy system.
In closing remarks, Aparo underscored that safeguarding is “a shared responsibility” in a changing world. He called for continued investment in monitoring equipment, capacity building, and open dialogue among all stakeholders to guarantee that nuclear energy can safely contribute to climate mitigation goals.
As the world grapples with limiting global warming to well below 2 °C, the IAEA’s efforts to refine verification processes represent a step toward ensuring that nuclear power supplies reliable, low‑carbon electricity without compromising security or environmental safety.
