Russian President Vladimir Putin on Wednesday ordered his government to take control of Ukraine's Zaporizhzhia nuclear power plant, Europe's largest, as the U.N. nuclear watchdog warned that the power supply to the site was "extremely fragile."
However, the boss of Ukraine’s state energy agency announced he was taking over the Zaporizhzhia nuclear power plant (ZNPP), which has become a focus of international concern due to the possibility of a nuclear disaster after shelling in the area for which Moscow and Kyiv have blamed each other.
Russia captured the Zaporizhzhia plant in March shortly after invading Ukraine, but Ukrainian staff have continued to operate it.
The plant is located in the southern Ukrainian region also called Zaporizhzhia, one of four regions that Putin formally incorporated into Russia on Wednesday in a move condemned by Kyiv as an illegal land grab.
"The Zaporizhzhia nuclear plant is now on the territory of the Russian Federation and, accordingly, should be operated under the supervision of our relevant agencies," RIA news agency quoted Deputy Foreign Minister Sergei Vershinin as saying.
Putin later signed a decree that designated the ZNPP "federal property."
"The government will ensure that the nuclear facilities at the plant... are integrated as federal property," the executive order said.
Russia's nuclear power operator Rosenergoatom said it would conduct an assessment of how to repair damage to the plant's infrastructure and would transfer all the existing Ukrainian employees to a new Russian-owned organization.
"The new operating organization is designed to ensure the safe operation of the nuclear power plant and the professional activities of the existing plant personnel," it said in a statement.
Ukraine says it's taking control
Meanwhile, the head of Ukraine's state nuclear energy company said he was taking charge of the ZNPP and he urged workers there not to sign any documents with its Russian occupiers.
"All further decisions regarding the operation of the station will be made directly at the central office of Energoatom," Petro Kotin said in a video address posted on the Telegram messaging app.
"We will continue to work under Ukrainian law, within the Ukrainian energy system, within Energoatom," Kotin said.
His comments followed the brief detention by Russian forces last weekend of the ZNPP's Ukrainian director Ihor Murashev. The International Atomic Energy Agency (IAEA) later said that Murashev had been released but would not return to his old job.
Energoatom said earlier Wednesday, after the plant's operating company was moved to Moscow, that Russia was "creating pseudo-enterprises with the names of Ukrainian companies."
"It's just a pity that they are trying to involve Ukrainian nuclear professionals, who have been heroically working under ... occupation for more than seven months" at the Zaporizhzhia plant, it said on social media.
IAEA chief Rafael Grossi is currently in Ukraine for further consultations on "agreeing and implementing a nuclear safety and security protection zone around the ZNPP as soon as possible," the U.N. agency said.
Grossi on Wednesday reiterated his concerns about the power supply to the plant.
"The situation with regards to external power continues to be extremely precarious. We do have at the moment external power but it is, I would say fragile. There is one line feeding the plant," he told the Energy Intelligence Forum in London via a telephone link.
Grossi is also due to visit Moscow this week, and Russia's state-owned TASS news agency said he might also visit the ZNPP after traveling there last month with a team to inspect damage caused by shelling in the vicinity.
Before Russia's invasion, the plant produced about one-fifth of Ukraine's electricity and nearly half the energy generated by the country's nuclear power facilities.
