Japan Raises Possibility of Breach in Reactor Vessel

So Some of the Japanese Nuclear guys, believe a Containment vessel has been breached, this is not good for anybody.
If the bottom has cracked (From the earthquake) that means that all the water they have been pumping into it has been leaking into the ground, this would devastate the area for decades; ground water, soil, everything will be contaminated.
If it's the top, then we have Radioactive steam spewing into the atmosphere!
Does it get ant better than this?

The development, described at a news conference by Hidehiko Nishiyama, deputy director-general of the Japan Nuclear and Industrial Safety Agency, raises the possibility that radiation from the mox fuel in the reactor — a combination of uranium and plutonium — could be released.

One sign that a breach may have occurred in the reactor vessel, Mr. Nishiyama said, took place on Thursday when three workers who were trying to connect an electrical cable to a pump in a turbine building next to the reactor were injured when they stepped into water that was found to be significantly more radioactive than normal in a reactor. The No. 3 unit, the only one of the six reactors at the site that uses the mox fuel, was damaged by a hydrogen explosion on March 14. Workers have been seeking to keep it cool by spraying it with seawater along with a more recent effort to restart the reactor’s cooling system.
