Don't worry, folks! The crisis at Japan's Fukushima Dai-ichi nuclear power plant should be "over by the end of the year," according to a timeline from plant operator Tepco. "Over," in this case, means that the reactors will be cooled. (Radiation leaks will be "reduced" in three months.) Once "cold shutdown" is achieved, the reactors will be entombed in concrete and contaminated soil will be cleaned up; right now, Tepco is taking readings at the damaged plant through the use of remote-controlled robots.
