Chernobyl shelter safely placed over exploded reactor

Ukraine on Tuesday installed the world's largest movable metal structure over the Chernobyl nuclear power plant's doomed fourth reactor to ensure the safety of future generations across Europe.

The giant arch's height of 108 meters made it taller than New York's Statue of Liberty while its weight of 36,000 tons is three times heavier that the Eiffel Tower in Paris.

The $1.6-billion structure had been edged into place over an existing crumbling dome that the Soviet Union built in haste when disaster struck three decades ago on April 26.
