The flow of radioactive water leaking into the Pacific Ocean from the crippled Fukushima Daiichi nuclear power plant has stopped following the injection of a chemical agent, a TEPCO spokesman said late this afternoon.

The details are still sketchy. Both Time (via The AP) and Dow Jones had bare bones briefs that were little more than restatements of the original story from The Kyodo news agency, which broke the news.

CNN, which originally had just a breaking news banner, ran a longer story that dealt with some of the background of the leakage, and provided some startling statistics, including this one: "Overall, the dump equates to about 3 million gallons, noted Gary Was, a nuclear engineering professor from the University of Michigan."  (This figure refers to both the leak and radioactive water purposely leaked into the ocean).

Reuters also ran a longer piece (and the only bylined one of the bunch), which pointed out, once again, that Japan is trying to contain the worst nuclear crisis since Chernobyl. Both The New York Times and The Huffington Post ran the Reuters piece.

To stop the leak, which was discovered on Saturday, TEPCO injected 400 gallons of "water glass" (sodium silicate).  Previously Japanese and U.S. official had considered using resin, robots and even a giant tarp to stop the flow of radioactive water.
