Tepco released some post-earthquake  informations about the situation of the Fukushima Daiichi Nuclear Power Station after the earthquake off the coast of Fukushima Prefecture that occurred around 5:59 am today, November 22.

“At Fukushima Daiichi Nuclear Power Station, at 6:06 am after the earthquake occurred. As a precaution, contaminated water transfer from the reactor building basements was stopped after the quake. It was restarted at 3:19pm.

Similarly, the Reverse Osmosis desalination system was stopped at 6:17 am, and restarted at 3:44 pm. The cesium adsorption system was stopped at 6:23 am, and restarted at 4:47 pm. Other water treatment systems were stopped at 6:12 am and restarted at 4:20 pm.

Since we confirmed that there was no abnormality after the earthquake, we resumed operation.

Also, we patrolled each Unit 1 to 6 equipments, our patrol was completed by 4:06 pm and we confirmed the following troubles:

– Damages to the south side silt fences of Units 1 to 4 and the north side silt fences of 5 and 6 units on the port, these are used to try to keep small radioactive debris from leaving the port.

– A puddle (about 2 m × 3 m) was found near the common spent fuel pool, thought to be caused by sloshing of the pool during the quake.

We will carry out the restoration work as soon as preparations are completed.”

Tepco did not mention anything about the storage tanks up on the hill. Those aging bolt together tanks, still partially in use, containing contaminated water, are a major concern, being the most vulnerable to be damaged by an earthquake.

According to JMA (Japan Meteorological Agency), they observed over 85 aftershocks by 11:00 AM (JST) of 11/23/2016, out of which 7 quakes of seismic intensity over 3. They warn the same level of the earthquake (M7.4) may happen again this week, with possible Tsunami.
