Tokyo Electric Power Co (TEPCO) workers work on waste water tanks at Japan's Fukushima Daiichi nuclear plant in the town of Okuma, Fukushima prefecture in Japan on June 12, 2013.
Water in all its forms has caused trouble at the ruined Fukushima nuclear plant this week. They are reminders that the problems are far from over.
March 9, 2012 Though the immediate nuclear crisis in Japan has passed, the process of securing and stabilizing the radioactive materials from the melted-down reactors will be a long, expensive slog. Recovery workers will also need to decontaminate the area surrounding the plant.

September 13, 2011 Six months after the accident at the Fukushima nuclear plant, the Japanese government has declared eight areas near the reactors as potential no-go zones for the next two decades. Many residents remain homeless. Beyond the hot zone, many people have decided to stay, but are worried about elevated radiation levels.
September 12, 2011 Since Japan's nuclear accident in March, about 500 Japanese seniors have signed up to work at the dangerous plant. They say it's better that they risk their lives than the younger workers at a job that has been called courageous — and suicidal.
