Japanese nuclear plant continues its radioactive spill into oceanBy Julie Makinen and Thomas H. Maugh II, Los Angeles Times

Reporting from Tokyo and Los Angeles— Workers at the Fukushima Daiichi nuclear power plant failed for a second day to stem the flow of radioactive water into the ocean as plastic injected into the leak Sunday failed to form a plug.
Workers had discovered an 8-inch crack in a concrete channel at the lower levels of reactor No. 2 where radioactive water had been accumulating after it had been sprayed onto the reactor to cool it. The crack was spewing the contaminated water into the ocean, which may explain the high levels of radioactivity detected offshore near the plant.
On Saturday, workers attempted to pump concrete into the crack to seal it, but the concrete would not set before it was washed away by the flow of seawater.
On Sunday, engineers attempted to plug the leak with a mixture of sawdust, shredded paper and a polymer or plastic that expanded to 500 times its normal size when exposed to water. They had then hoped to pour concrete on top of the polymer to form a permanent seal, but the polymer did not form a plug either, and as of Sunday night, water was continuing to flow into the ocean.
Radiation levels in the water are an estimated 1,000 millisieverts per hour, a high but not immediately lethal dose.<snip>
