Is Japan almost out of the red zone? The executive director of the U.S. Nuclear Regulatory Commission announced Monday that Japan's nuclear disaster is "on the verge of stabilizing," even while Japanese workers had to temporarily halt relief efforts at one reactor. "The fact that offsite power is close to being available for use by plant equipment is the first optimistic sign that things could be turning around," said U.S. official Bill Borchardt. Fukushima Daiichi's fifth and sixth power units have been restored and connected to diesel generators. TEPCO officials announced that Units 1 and 2 should be up and running by the end of Monday, and Units 3 and 4 in the next couple of days.
