"TOKYO -- The temperature fell to minus 8.7 degrees Celsius on Sunday morning near Japan's crippled nuclear power plant, causing water pipes and valve seals to rupture, leaking tons of water."
"Workers at the Fukushima Daiichi nuclear plant discovered Sunday that the damaged pipes spilled nearly eight tons of water from 14 locations. Two additional water leaks were discovered today, according to plant operator Tokyo Electric Power Company.
The leaked water included radioactively contaminated water that has been purified, TEPCO said, adding the contamination level is low. The leaks have not spilled out of the plant or flowed into the ocean, the company said."
