              FILE Volunteers work to clean the debris on a site where several houses were destroyed after a Russian attack at a residential area in Zaporizhzhia, Ukraine, Sunday, Oct. 9, 2022. Ukrainians are once again anxious and alarmed about the fate of a nuclear power plant in a land that was home to the world's worst atomic accident in 1986 at Chernobyl. The Zaporizhzhia nuclear plant, Europe's largest, has been occupied by Russian forces since early in the war, and continued fighting nearby has heightened fears of a catastrophe that could affect nearby towns in southern Ukraine or beyond.
