More trouble brewing at the Fukushima-1 nuclear complex. You know, if you keep pouring water into a container it tends to fill and overflow:

UPDATE, Thursday, June 2, 2011. Concern is growing that radioactive water in the reactor buildings and other facilities at Fukushima Daiichi may again be released into the ocean. Water levels have been rising, partly as a result of continued pumping of water for cooling and partly as a result of heavy rains last weekend from Typhoon Songda, which fortunately only grazed the Fukushima site. A Tepco spokesman said today that radioactive water could begin to overflow trenches within 5-7 days.
