KYIV, Oct 2 – The Zaporizhia nuclear power plant (ZNPP), occupied by Russian troops, is preparing to once again use reactor unit 4 to generate steam for various safety functions at the facility, following repairs that put it out of action for several weeks, IAEA Director General Rafael Mariano Grossi has said.

"The ZNPP this week began transitioning it from cold to hot shutdown. Once this is done, the ZNPP plans to return unit 6 to cold shutdown. Unit 6 has been providing steam in hot shutdown since mid-August, after a water leak was detected in one of unit 4's four steam generators," the IAEA said in a report on its website.
