Fukushima Daiichi nuclear disaster

A) Introduction

Hello! Today’ blog is about one of the well-known nuclear disasters happened in 2011. It was the Fukushima Daiichi nuclear disaster, which occurred in Japan and the pictures shown above was the incident.

B) Brief summary of this disaster:

1. This disaster happened on March 11, 2011. In Chinese, we addressed it ‘福島第一原子力発電所事故’.

2.The significance of this accident was because there a number of equipment  failures, nuclear meltdowns, and releases of radioactive materials. This event happened after Tohoku earthquake and tsunami.

3. INES (International Nuclear Event Scale) rated this outcome as level 7.

4. Sadly, there were some injuries and casualties found afterwards.

C) Reactors

Reactors played a big role before this disaster. They were either destroyed or under operator after the accident.

–Reactors 1 – 6: Boiling water reactor (types), general electric, Toshiba, Hitachi (suppliers)

– Reactor 1: a. damaged after the incident b. supplied by Genetic Electric c. built with Mark I type (light bulb torus) containment structures d. constructed in 1967 e. a 460 MW electric power

-Reactor 2: a. supplied by Genetic Electric b. shutdown after the incident c. built with Mark I type (light bulb torus) containment structures d. constructed in 1969 e. a 784 MW electric power

-Reactor 3: a. supplied by Toshiba b. damaged after the incident c. built with Mark I type (light bulb torus) containment structures d. constructed in 1970 e. a 784 MW electric power

-Reactor 4: a. supplied by Hitachi b. shutdown after the incident c. built with Mark I type (light bulb torus) containment structures d. constructed in 1973 e. a 784 MW electric power

-Reactor 5: a. supplied by Toshiba b. damaged after the incident c. built with Mark I type (light bulb torus) containment structures d. constructed in 1972 e. a 784 MW electric power

-Reactor 6: a. supplied by Genectic Electric b. shutdown after the incident c. built with Mark II type (light bulb torus) containment structures d. constructed in 1973 e. a 1100 MW electric power

-Reactor 7,8: Cancelled after incident occurred b. planned to rebuild in 2016 (reactor 7), rebuild in 2017 (reactor 8)

D) Causes and effects / advantages / disadvantages / solutions ( recommendations)

– Video haring: Some people said this incident is a man-made disaster. Why so?

-Disadvantages for having nuclear power plant: would be the constant argument on the safety standards of nuclear power plants (From this event: the more nuclear power plants are built, the higher the probability of a disastrous failure somewhere in the world)

-Some lessons learn from this incident:

Lesson 1: continued health monitoring

Lesson 2: keep on the effective, long-term cooperation

E) Opinions and comments

Picture sharing: Personally and honestly, I did not want to to see such event like the above picture happen again. Burning and destruction not only cause people’s lives, also wasting money and time to rebuild. I do not care if it is man-made because the accident had occurred already. Be brief, I hope we have a safe industry.
