The World Holds Its Breath Over Bushehr

Four times in recent weeks, projectiles have struck near Iran’s Bushehr nuclear power plant, and four times the world has narrowly avoided a catastrophe that would dwarf every other consequence of the current Middle East conflict. The latest incident, reported to the International Atomic Energy Agency on April 4th, killed a member of the plant’s security staff and sent shockwaves and fragments into an on-site building. No increase in radiation levels was detected, but the margin for comfort grows thinner with each strike.

Rafael Grossi, the IAEA’s director general, described himself as “deeply concerned,” which in the measured language of nuclear diplomacy is roughly equivalent to alarm. He has repeatedly emphasised that nuclear power plant sites must never be attacked, warning that auxiliary buildings contain vital safety equipment. A previous strike on March 18th destroyed a structure just 350 metres from the reactor itself.

Grossi has invoked the agency’s seven pillars for nuclear safety in armed conflict, a framework first developed in the shadow of the war in Ukraine. The pillars cover everything from the physical integrity of reactor buildings and the continuity of off-site power supply to the freedom of operating staff to make decisions without undue pressure. In the current environment, several of these conditions are under severe strain.

The implications extend beyond Iran. As Grossi reminded IAEA board members in Vienna, many countries in the region that have come under military attack operate nuclear power plants and research reactors. A miscalculation at Bushehr would not be a local tragedy; it would be a global one. The fact that the world is discussing it in terms of “fortunately, no radiation was detected” is itself a measure of how perilously close to the edge this conflict has already taken humanity.
