Water, Water, Everywhere, But Not Enough To Waste

There's also a thriving local grocery co-op; a busy farmer's market; even a classy restaurant — Claire's — where almost anything you eat grew or grazed on land nearby.

Explainers: Inside Japan's Nuclear Crisis

Plutonium In Fuel Rods: Cause For Concern?

Some outside experts are particularly concerned about high levels of plutonium in one of the damaged Japanese reactors. About 6 percent of the fuel rods in reactor No. 3 at the Fukushima Dai-ichi power plant are made from so-called "mixed-oxide" (MOX) fuel, which contains plutonium as well as uranium.
