MECHANICSVILLE, Va. — I woke up with the news of the explosion at the Fukushima Daiichi nuclear plant in Okuma, Fukushima Prefecture, Japan, and cooling troubles at the nearby Fukushima Daini nuclear plant in Tomioka (also in Fukushima Prefecture).
So far there has only been small-scale releases of radioactive materials—not as much as had been released in the Three Mile Island incident 1979.
According to Tokyo Electric Power Co. (TEPCO), which operates the plant, the explosion at Fukushima Daiichi reactor No. 1 was a hydrogen explosion which destroyed an outer wall and collapsed the roof of the building that housed the reactor. While the reactor’s containment shell remains intact, there remains a risk of a complete meltdown—and even greater disaster.
For those of you worried about the potential for radioactive fallout reaching your homes in North America, I offer this service (until something better comes along or the crisis ends): I will generate and post surface and upper-level weather maps for you to see the pressure and wind fields across the North Pacific Ocean. These will be posted without comment, so it is up to you to find someone who can help you make sense of them.
