Breach in Reactor Suspected at Japanese Nuclear Plant

Officials in Japan have increased the radius of evacuation from around the Fukushima nuclear power plant after workers' feet were burned by water with 10,000 times more radioactive contamination than normal. That could mean a breach in the containment vessel of Reactor Number 3 and a release of plutonium as well as uranium. William Tobey, former deputy administration of the National Nuclear Security Administration, is now at Harvard's Kennedy School of Government.
