Chernobyl shelter safely placed over exploded reactor

CTV News Channel: 'They're heroes' CTV's Dan Riskin reports on a giant shelter being built over the site of Chernobyl in order to prevent further deadly radiation leaks.

CHERNOBYL, Ukraine - A massive shelter has finally been installed over the exploded reactor at the Chernobyl nuclear plant, one of the most ambitious engineering projects in the world.

The half-cylinder-shaped shelter began being moved toward the reactor on a system of hydraulic jacks two weeks ago and reached its destination Tuesday, a significant step toward liquidating the remains of the world's worst nuclear accident, 30 years ago in what is now Ukraine.

Workers will now begin dismantling unstable parts of the original cover, the so-called sarcophagus, which was built over the reactor shortly after the explosion to contain radiation.

The new shelter is 275 metres (843 feet) wide and 108 metres (354 feet) tall and cost 1.5 billion euros, according to the European Bank for Reconstruction and Development.
