Fukushima Reactors Stable After 7.3 Magnitude Quake

Fukushima Reactors Stable After 7.3 Magnitude Quake

A 7.3 magnitude earthquake struck Japan overnight, triggering tsunami warnings across the island nation. The warnings were lifted soon after and the quake caused very little damage.
We’ve got out eyes on the situation at Fukushima Daiichi, and things there look quiet according to ABC News: “No damage has been reported at monitoring posts and water treatment facilities at the reactors … All the workers were moved to higher ground on the site and told to stay inside after the tsunami warning.”http://safetyfirst.nei.org/japan/fukushima-reactors-stable-after-7-3-magnitude-quke/

12/7 Japan Earthquake - No Nuclear Plant Damage Reported

At 5:18 PM Tokyo time on December 7, a magnitude 7.3 (Richter) / 4 (Japanese intensity scale) earthquake occurred in roughly the same region as the Great Tohoku quake.  All tsunami warnings were lifted a short time ago as this report is written (7:40 PM Tokyo time, 5:40 AM Eastern time US) and only a one meter tsunami was observed in some locations. 

Tokyo Electric Power Company has released the following statement about the quake, relative to the Fukushima Daiichi and Fukushima Daini nuclear power plants:

Announcements

At around 5:18 PM on Friday, December 7, an earthquake (seismic intensity of 4) occurred in Hamadori region in Fukushima Prefecture. The conditions of the nuclear power stations are as follows.

Fukushima Daiichi Nuclear Power Station
There has been no problem found with the monitoring post data, Units 1-6 main plant parameters, reactor water injection system, accumulated water transfer, water treatment facility and other facilities. Currently, no injury has been reported due to the earthquake. The maximum acceleration observed in the power station was 26.2 Gal (horizontal direction) at the foundation ground in Unit 6 Reactor Building.

Fukushima Daini Nuclear Power Station
The maximum acceleration observed in the power station was 26.0 Gal(vertical direction) at the foundation ground in Unit 1 Reactor Building.
The fluctuation of the monitoring post readings is being maintained within the range of normal fluctuation before and after the earthquake and currently no radiation impact to the outside of the power station has been reported due to the earthquake. No injury has been reported due to the earthquake.

We will continue investigating the conditions of the equipments/facilities in the power stations.

Tohoku Electric Power is investigating all conditions at Onagawa Nuclear Station but as of now reports no damage.
