‘It can’t go on like this’: Power restored to Ukrainian nuclear plant but situation untenable, says IAEA

External power has been restored to Ukraine’s Zaporizhzhya Nuclear Power Plant (ZNPP) two days after it
experienced a complete blackout amid Russian shelling, the UN’s
International Atomic Energy Agency (IAEA) said on Saturday. Both of the
plant’s external power lines, a 750kV line and a 330kV back-up line, were
repaired on Friday, re-establishing power to the plant’s six reactors by
10pm.

The reactors have been shut down, although reactors 5 and 6 are in
semi-hot shutdown to provide steam to the site, and arrangements are being
made to further heat-up units 5 and 6 to achieve a “hot shutdown”
state. The other four units in Europe’s biggest nuclear plant remain in
cold shutdown. Ukrainian staff have operated the plant under Russian
occupation since March. The IAEA has had four experts embedded among the
Ukrainian staff since 5 September. It rotated a new team in on Thursday.


Last week, shelling damaged the last two high-voltage lines
connecting ZNPP to the country’s grid, putting it in full blackout mode and
necessitating the activation of all 20 of its diesel back-up generators.
The IAEA said the lines were damaged some 50-60 kilometres from the plant
in Ukrainian-controlled territory.

“The repeated power outages all too clearly demonstrate the extremely serious nuclear safety and security
situation this major nuclear power plant is facing,” said IAEA director
general Rafael Mariano Grossi. He continued: “So far, the brave staff of
the Zaporizhzhya Nuclear Power Plant have always managed to maintain the
safe operation of the six units. But it can’t go on like this. I have
repeatedly called for the urgent establishment of a nuclear safety and
security protection zone around the Zaporizhzhya Nuclear Power Plant to
prevent a nuclear accident. We can’t afford to lose any more time. We must
act before it is too late.”
