Fukushima Daiichi Unit 3 is not going to explode

Steam heat? What is happening at Fukushima Daiichi?

Beginning on Monday December 30, 2013, the Internet has been flooded with conjecture claiming that Fukushima Daiichi Unit 3 is ready to explode. Fairewinds Energy Education has been inundated with questions about the very visible steam emanating from Fukushima Daiichi Unit 3. Our research, and discussions with other scientists, confirms that what we are seeing is a phenomenon that has been occurring at the Daiichi site since the March 2011 accident.

It is winter and it is cold through out much of the northern hemisphere. Hot water vapor has been released daily by each of the four Fukushima Daiichi nuclear power plants since the accident. We believe that is one of the reasons TEPCO placed covers over Daiichi 4 and 1. Sometimes the steam [hot water vapor] is visible and sometimes it is not. If you have been outside on a cold winter day, you have personally experienced that phenomenon when you see the breath you exhale form a cloud in the cold air. The technical explanation is that hot water vapor becomes visible when it comes in contact with cold air and condenses. During the winter months in the Fukushima Prefecture, the sea air is cold and moist, thus forming the ideal conditions to see the released steam.
