US Energy Secretary Chris Wright described Iran's lack of transparency toward the IAEA as unacceptable at the IAEA's 70th General Conference in Vienna, the capital of Austria. Wright said Iran had been given sufficient time to fulfill its obligations and should not develop or acquire nuclear weapons.
Wright called on Iran to fully cooperate with the IAEA, fulfill its safeguards obligations and provide the access necessary for the agency to carry out its mandate. He recalled that the IAEA Board of Governors had taken the necessary step to refer Iran's failure to meet its obligations to the United Nations Security Council.
Wright also addressed the US nuclear energy goals, saying the Trump administration aims to add 300 gigawatts to the country's nuclear power capacity by 2050.
Grossi warns of nuclear arms proliferation
IAEA Director General Rafael Grossi also spoke at the conference about the global risk of nuclear arms proliferation. Grossi said the Treaty on the Non-Proliferation of Nuclear Weapons remained the cornerstone of the global nuclear nonproliferation regime, adding that a world with more nuclear weapons and more countries possessing them would not be safer.
Grossi said inspections of Iran's nuclear program had deteriorated in 2026. He said inspectors had been forced to withdraw and noted that no field verification activity had been carried out in Iran for more than six months, except for an inspection conducted at the Bushehr Nuclear Power Plant in June.
Grossi said continuity of knowledge about Iran's stockpile of uranium enriched to up to 60 percent had not been maintained for more than a year. He said the inability to account for nuclear material and access facilities for verification purposes had caused serious nuclear proliferation concerns. Grossi called for a return to diplomacy and negotiations.
Grossi also announced that outstanding safeguards issues concerning Syria's nuclear activities from the period of the ousted Assad regime had been resolved. He said this progress had been achieved through Syria's transparency and cooperation.
Likhachev raises attacks on nuclear facilities
Alexey Likhachev, director general of Rosatom, also spoke at the conference. Likhachev claimed that nuclear facilities were being attacked almost every day and said their security must be an absolute priority regardless of their location.
Claiming that the Ukrainian military had been regularly attacking Russian nuclear power plants, Likhachev said attacks on the Russian-controlled Zaporizhzhia Nuclear Power Plant and the area where it is located had increased in recent months. Likhachev said tankers carrying diesel fuel needed for the plant's nuclear safety had been attacked last Friday.
Likhachev said the IAEA should not limit itself to recording the attacks and should clearly identify those responsible.
In addition to speeches by Grossi, Wright and Likhachev, the IAEA's 70th General Conference featured remarks on various topics.
