Impact of Japan Earthquake on Nuclear Power Plants: Fukushima Daiichi and Fukushima Daini

12 March 2011 Geoff Zeiss

Incidents stipulated in Article 15, Clause 1 of the Act on Special Measures Concerning Nuclear Emergency Preparedness have been reported by TEPCO for both Fukushima Daiichi and Fukushima Daini nuclear power plants.

This is the status of Fukushima Daiichi and Fukushima Daini Nuclear Power Plants as of 10:00 am March 12 Japan Time (08:00:00 p.m. Friday March 11 Eastern Time) reported by TEPCO.

Below is major impact to TEPCO’s facilities due to the Miyagiken-Oki
Earthquake that occurred yesterday at 2:46PM.

[Nuclear Power Station]

Fukushima Daiichi Nuclear Power Station:
  Units 1 to 3: shutdown due to earthquake
  Units 4 to 6: outage due to regular inspection
* The national government has instructed evacuation for those local
residents within 10km radius of the periphery.
* Measurement of radioactive material (Iodine, etc.) by monitoring car
indicates increasing value compared to normal level. One of the
monitoring posts is also indicating higher than normal level. We will
continue monitoring discharge of radioactive material from exhaust stack
and discharge canal, etc.
* Considering the increasing pressure with in the reactor containment
vessel of Unit 1, the national government has instructed us to
implement measures to reduce the pressure of the reactor containment
vessel (partial discharge of air containing radioactive materials) in
order to fully secure safety.

Fukushima Daini Nuclear Power Station:
  Units 1 to 4: shutdown due to earthquake
* The national government has instructed evacuation for those local
residents within 3km radius of the periphery and indoor standby for those
local residents between 3km and 10km radius of the periphery.
* At present, we have decided to prepare implementing measures to reduce
the pressure of the reactor containment vessel (partial discharge of air
containing radioactive materials) in order to fully secure safety.
These measures are considered to be implemented in Units 1 to 4 and
accordingly, we have reported and/or noticed the government agencies
concerned.
