KYIV, Ukraine—Europe’s largest nuclear plant has been reconnected to Ukraine’s electricity grid, allowing engineers to shut down its last operational reactor in an attempt to avoid a radiation disaster amid the fighting in the area.
The six-reactor Zaporizhzhia Nuclear Power Plant lost its outside source of power a week ago after all its power lines were disconnected because of shelling. It was operating in “island mode” for several days, generating electricity for crucial cooling systems from its only remaining operational reactor.
