Japan nuke plant reaches cold shutdown
Tokyo - Japan's prime minister has announced that the tsunami-devastated Fukushima Daiichi nuclear power plant has reached a "cold shutdown" and is no longer leaking substantial amounts of radiation.
Prime Minister Yoshihiko Noda's announcement on Friday marks a milestone nine months after the March 11 tsunami sent three reactors at the plant into meltdowns in the worst nuclear crisis since Chernobyl.
But experts noted that the plant remains vulnerable to more problems and will take decades to decommission the plant.
The crisis displaced about 100 000 people.
Officials are to start discussing allowing some residents to return to less contaminated areas. A 20km zone around the plant is expected to remain mostly off-limits for years.
