Ukraine says power has been restored to Chernobyl plant

Ukraine says it has restored a broken power line to the Chernobyl power plant, which in 1986 was the site of the world's worst nuclear disaster. The plant is currently held by Russian troops. 

Energy Minister Herman Halushchenko said that "heroes" from the national power grid company managed to restore the connection. The power is used to run pumps that keep spent nuclear fuel cool to prevent radiation leaks.

Ukraine said Wednesday that power had been cut to the site and that there was enough diesel fuel to run on-site generators for 48 hours. The International Atomic Energy Agency played down concerns, saying it saw little risk of the pools containing the spent fuel overheating even without electricity.
