Finnish Company Claims Its Copper Canisters Can Store Nuclear Waste for 100,000 Years

While the fate of America's Yucca Mountain appears to be sealed, Finnish company Posiva is moving forward with a cutting-edge nuclear waste storage facility that it claims will safely store radioactive waste in drums deep in the ground for 100,000 years. While challenges abound, a green light from the Finnish government expected by 2012 will make the site on Finland's Olkiluoto Island the first permanent nuclear waste repository in the world, opening the door for more to follow.

Robo-Sub Searches For Illegal Nuclear Waste in Mafia Shipwreck

Is the Mafia dumping radioactive waste in the ocean? One robot aims to find out

To scope out a suspected Mafia shipwreck that may hold nuclear material, Italian authorities sent in the robot.

A remote-controlled sub began filming a sunken vessel off Italy's southern coast over the weekend. That shipwreck may represent just one of 30 ships deliberately sunk in a rather sociopathic act of nuclear waste dumping.

Using Nano-Geometry to Create Better Concrete

Nano-treated concrete could endure for millennia, and provide a solution for very-long-term nuclear containment

The use of concrete dates back to ancient Rome, and the recipe hasn't changed much since then. Neither have some of concrete's drawbacks. In particular, the slow deformation known as "concrete creep" has afflicted structures from the Pantheon to the Pentagon. But MIT scientists believe they have solved the mystery of concrete creep, and thus opened the door to structures that will last tens of thousands of years.

Powering Cars With Toxic Waste

Scientists invent a uranium-eating molecule that could help turn nuclear junk into fuel

With global warming grabbing headlines, carbon-free nuclear power is gaining popularity—and with it, concerns over what to do with the spent uranium fuel. The largest long-term burial project, Yucca Mountain, has stalled, and even though uranium’s first trip through a reactor extracts only 5 percent of its energy, power plants in the U.S. don’t reprocess fuel. This is mainly because the most common form of uranium, an ion called uranyl, is extremely difficult to extract from the spent fuel rods. But a new Pac-Man-like molecule could change that.
