The International Atomic Energy Agency director general, Rafael Grossi, said the team was scheduled to arrive at the site later this week.
In a tweet, he emphasized the importance of safeguarding Ukraine’s and Europe’s largest nuclear plant.
Since March, Russian invaders have held the nuclear reactor.
Fighting in the area has raised international concerns for the site’s security, which is located in the southeast of Ukraine.
Russia and Ukraine have both been blamed for bombarding the region.
On Thursday, when the plant was momentarily cut off from Ukraine’s power grid and its backup generators came in to provide it with electricity, Ukrainian President Volodomyr Zelensky warned that Europe was “one step away” from a radioactive calamity.
It was the first time in the plant’s history that electricity was lost, he claimed, since flames had charred the overhead electrical wires.
Both Ukraine and Russia claimed the other was responsible for the attacks that led to the destruction. There was no way for the BBC to know for sure who was to blame.
The facility was taken over by the Russian military in early March, but it is still being run by Ukrainian personnel despite the challenging circumstances.
It is significant that the IAEA will be permitted to examine the site since the Kremlin has previously indicated that it would only allow foreign inspectors to tour the complex.
The Ukrainian government initially opposed an IAEA mission to Zaporizhzhia for concern that it would give Russia’s takeover of the nuclear facility more legitimacy.
“In or around the Zaporizhzhia nuclear power plant, a new event occurs almost daily. To waste any more time would be disastrous “the head of the IAEA said.
Experts think the plant’s sturdy walls make shelling around it less of a threat.
It poses serious risks if its electrical source is interrupted. If the electricity to the nuclear reactors and backup generators suddenly went out, the pumps cooling the hot reactor core would stop working, and the fuel within would begin to melt.
