Here is the latest update from the NEI’s Japan launch page:
UPDATE AS OF 9:15 P.M. EDT, THURSDAY, MARCH 17:
Tokyo Electric Power Co. said it hopes to activate the cooling system for Fukushima Daiichi reactor 2 “as early as Friday night” (Japan time). The company said it could restore power from the electric grid to reactor 2 by Thursday night (U.S. time).
The International Atomic Energy Agency reported that TEPCO completed connecting electrical cable from a makeshift transformer to reactor 2 at 4:30 A.M. EDT. Engineers were waiting to complete spraying sea water into the reactor 3 fuel pool before they restore power through the cable to the reactor 2 cooling system.
TEPCO says that if it can provide power supply to the other reactors, it could begin restoring some cooling functions. The company said that after fire trucks injected water into reactor 3’s fuel pool, radiation levels at the plant’s west gate dropped from 31 millirem per hour to 29 millirem per hour at 10:00 A.M. EDT.
NEI is trying to filter out as much “noise” as possible from these updates so you can trust that the content is based on the best possible information. Remember that Japan is at least 13 hours ahead of the United States, so things happening on Friday morning there are happening on Thursday evening here.
