Ukraine announces the shutdown of the last operating reactor at the Zaporizhia nuclear power plant

"Today, September 11, 2022, during the night at 03:41 (01:41 GMT) unit number 6 of the (power plant) was disconnected from the power grid," according to a statement from Ukrainian operator Energoatom. “Preparations are underway for its cooling,” adds the operator.

According to Energoatom, a cold shutdown is "the safest state" for the reactor, which for three days had been the only one to produce the electricity needed to cool the nuclear fuel and to ensure the safety of the site.

The decision to shut it down was taken when the site's external power supply was restored "last night" with one of the transmission lines.

“In the event of further damage to the transmission lines connecting the site to the electrical system – the risk of which remains high – the internal needs (of the site) will have to be provided by generators running on diesel,” warns Energoatom.

In its statement, Energoatom reiterates its call for the establishment of a demilitarized zone around the plant, the only way according to the operator to ensure its security.

Ukraine and its allies have expressed growing concerns about the safety of the Zaporizhia plant. For weeks, confusion has reigned around the site of the power plant, hit by multiple strikes for which kyiv and Moscow accuse each other.

On Friday, the International Atomic Energy Agency (IAEA) reported a "total water and electricity cut" in the Ukrainian city of Energodar (south), where the Zaporizhzhia nuclear power plant is located. , a situation that "compromises the safety of operations".

"It is totally unacceptable. It cannot continue," said the director general of this UN agency, Rafael Grossi, in a press release, calling for "immediately to cease the bombardments in the area".
