A view of empty houses in the deserted town of Pripyat near the closed Chernobyl nuclear power plant Ukraine Tuesday, Nov. 27, 2012. Workers on Tuesday raised the first section of a colossal arch-shaped structure that is eventually to cover the exploded reactor at the Chernobyl nuclear power station. Project officials on Tuesday hailed the raising as a significant step in a complex effort to liquidate the consequences of the world's worst nuclear accident, in 1986. (AP Photo/Efrem Lukatsky)
