Thursday Update

From NEI’s Japan Earthquake launch page:

UPDATE AS OF 11:30 A.M. EDT, THURSDAY, APRIL 7:
A 7.1 magnitude aftershock in northeastern Japan today caused no damage to nuclear power plants in the area, the Nuclear and Industrial Safety Agency reported. Plant employees at the Fukushima Daiichi, Fukushima Daini and Onagawa plants were evacuated for safety after the tremor, which struck at 11:32 pm JST.

Two of the three electric power lines that supply the Onagawa site were down, officials said, but operations at the plant’s three reactors were continuing as normal with power from the remaining line. There was no change in radiation levels near the plant.

The reactors at the three sites had been shut down since the magnitude 9.0 earthquake on March 11.

There were no damages reported at the Fukushima Daiichi and Daini plants. At Daiichi, where engineers have been working to cool reactors since the March 11 earthquake, fresh water injection continued.
