In a statement released by the IAEA, Mr. Grossi said he had been informed by Ukrainian authorities that, although regular staff continue to operate the Zaporizhzhya Nuclear Power Plant, any action of plant management – including measures related to the technical operation of the six reactor units – requires prior approval by the Russian commander of the Russian forces that took control of the site last week.
Mr. Grossi said that this development contravenes one of the seven pillars of nuclear safety and security that he outlined at a meeting of the IAEA’s Board of Governors on 2 March: that “operating staff must be able to fulfil their safety and security duties and have the capacity to make decisions free of undue pressure”.
Communication severely restricted
Ukraine’s nuclear regulator has informed the IAEA that it is having major problems communicating with staff operating Zaporizhzhya, due to Russian forces at the site switching off some mobile networks and blocking the internet. Some mobile phone communication is understood to still be possible, albeit with poor quality, but fixed phone lines, as well as e-mails and fax, are reportedly no longer functioning.
The IAEA noted that this situation contravenes another of its seven indispensable pillars of nuclear safety, that there must be “reliable communications with the regulator and others”.
“I’m extremely concerned about these developments that were reported to me today”. Said Mr. Grossi. “Just a few days after I presented the seven main elements of nuclear safety and security to the IAEA Board, several of them are already being compromised. In order to be able to operate the plant safely and securely, management and staff must be allowed to carry out their vital duties in stable conditions without undue external interference or pressure”.
“The deteriorating situation regarding vital communications between the regulator and the Zaporizhzhya NPP is also a source of deep concern, especially during an armed conflict that may jeopardize the country’s nuclear facilities at any time”, continued the Director-General. “Reliable communications between the regulator and the operator are a critical part of overall nuclear safety and security”.
Radiation levels normal
Despite the communication issues, the regulator was able to provide updated information about the operational status of the Zaporizhzhya NPP to the IAEA, and to confirm that radiation levels there remained normal.
Operational teams at the plant are now rotating in three shifts but, the regulator added, the availability and supply of food is limited, which is having a negative impact on staff morale.
Chernobyl and Mariupol safety fears
Responding to reports that the technical staff and guards at the site of the Chernobyl nuclear accident site have not been rotated since 23 February, Mr. Grossi called on the Russian forces controlling the site to allow them to be relieved by other colleagues and rest, in order to carry out their jobs safely and security.
The Ukraine regulator has informed the IAEA that communication with Chernobyl is currently limited to emails.
In another worrying development, the regulator said that all communications have been lost with the enterprises and institutions in the port city of Mariupol that use category 1-3 radiation sources, and there is no information about their status. Such radioactive material, warned the IAEA, can cause serious harm to people if not secured and managed properly.

The accident at the Chernobyl nuclear power plant on 26 April 1986 was one of the most serious nuclear accidents ever.
