NOVA: Building Chernobyl's Mega Tomb In 1986, in the heart of the Ukraine, the Chernobyl nuclear reactor exploded, releasing 400 times more radiation than the Hiroshima Bomb. It was the world's worst nuclear disaster. Thirty workers died. 50,000 people fled the nearest city. And radioactive fallout made an area larger than Long Island a no-go zone. Hastily, a so-called ""sarcophagus"" was built to contain the radioactive materials that lingered at the site after the explosion. But thirty years later, the sarcophagus is crumbling, and another disaster at Chernobyl looms.
Now, an international team of engineers is racing the clock to assemble one of the most ambitious superstructures ever built… an extraordinary 40,000 ton, 1.5 billion dollar mega dome to entomb the crumbling remains of the Chernobyl nuclear reactor. Battling arctic winter weather - and lethal radiation - this is the inside story of the epic race to build Chernobyl's MegaTomb.
VIDEO USAGE RIGHTS
Why the AV version? Because it provides additional usage options for PBS videos. AV versions come with limited performance rights so they can be shown in classrooms, at PTA meetings, during after school programs, and transmitted on a closed-circuit system within a building or on a single campus. They also can be enjoyed in admission-free public screenings, which also makes them ideal for use by library patrons and businesses involved in community clubs and organizations.
