This is heartening news:
Japanese Earthquake Update (17 March 17:55 UTC)
Japanese authorities have informed the IAEA that engineers were able to lay an external grid power line cable to unit 2. The operation was completed at 08:30 UTC.
They plan to reconnect power to unit 2 once the spraying of water on the unit 3 reactor building is completed.
The spraying of water on the unit 3 reactor building was temporarily stopped at 11:09 UTC (20:09 local time) of 17 March.
The IAEA continues to liaise with the Japanese authorities and is monitoring the situation as it evolves.
If this is successful, the plant will be able to take over from the workers in cooling the fuel in the reactor.
