Japan's Fukushima nuclear plant operator says another tank leaked toxic water

(Reuters) - The operator of Japan's crippled Fukushima nuclear plant said on Thursday another tank holding highly contaminated water overflowed, probably sending the liquid into the Pacific Ocean, in the second such breach in less than two months.

Tepco said the water that leaked contained 200,000 becquerels per liter of beta-emitting radioactive isotopes, including strontium 90. The legal limit for strontium 90 is 30 becquerels per liter.

About 430 liters (113 gallons) of water spilled over a period of as much as 12 hours after a worker misjudged how much could be held by the tank, which is tilting because of an uneven location, Tepco spokesman Masayuki Ono told reporters.
