The International Atomic Energy Agency has announced concrete measures that must be implemented in an effort to avoid “a catastrophic incident” at the Russia-controlled Zaporizhzhia nuclear power station in Ukraine.

IAEA director-general Rafael Grossi told the United Nations Security Council on Tuesday (30 May) that the measures are needed to help ensure nuclear safety and security at the six-unit Zaporizhzhia – the largest nuclear station in Europe – to prevent a dangerous release of radioactive material and ensure the integrity of the facility.

Grossi said there should be “no attack of any kind from or against the station”, in particular targeting the reactors, spent fuel storage, other critical infrastructure or personnel.

Zaporizhzhia, in the south of Ukraine close to the frontline, should not be used as storage or a base for heavy weapons such as multiple rocket launchers and tanks, or for military personnel that could be used for an attack from the facility.
