The head of the United Nations’ nuclear watchdog warned Wednesday that a projectile strike near Iran’s Bushehr nuclear power plant risked crossing the “reddest line” of nuclear safety, as fighting between the U.S., Israel and Iran intensifies.
Concerns Over Nuclear Facility
A direct hit on an operating nuclear reactor like Bushehr could trigger a severe radiological incident, according to International Atomic Energy Agency Director General Rafael Grossi. Yet, a recent strike caused no apparent damage to the plant’s core systems.
Grossi stated, “An accident on an operating nuclear power plant would be something very, very serious,” and added, “What we have is the reddest line of all that you have in nuclear safety.” He also noted, “The possibility of dispersion in the atmosphere of radioactivity is very high if you get to the core of the reactor.”
The projectile struck part of the Bushehr nuclear power plant complex in recent days, marking the closest known impact on an operating reactor since the conflict began. The cause of the strike and the responsible party remain unclear.
Grossi indicated the impact hit a smaller structure within the facility—possibly a laboratory or auxiliary building—and did not affect the reactor itself or cause any reported casualties. He explained that nuclear power plants include administrative buildings and support infrastructure beyond the reactor core, increasing the chance of a strike hitting the site without directly damaging the reactor.
The agency has not conducted an on-site inspection, as “independent” verification requires physical presence, but available imagery suggests the damage is not significant. However, Grossi stressed the risks would be far more severe if the reactor were struck.
Unlike other nuclear facilities, an operating reactor contains a live core undergoing nuclear fission, meaning a direct strike could release large amounts of radioactive material into the environment.
Grossi stated there is broad international understanding that nuclear power plants should not be targeted during conflict. Iran blamed the United States and Israel for the strike, though this claim has not been independently verified. U.S. Officials have not confirmed involvement, and Israel’s military said it was not aware of any such strike.
