Lol... This is from one of the comments below the article (I did not write this):

"Feet? Degrees Fahrenheit? This is so funny. How many feet wide is your nuclear reactor core? How many stones does it weigh? Surely this must be a joke.

The article is laden with namedropping but has no information at all on all crucial points such as the actual explosion. That anyone takes this seriously escapes me.

And, seriously? Measurements in body part lengths? Any engineer who went to school must have learned the proper system. I seriously doubt this article is genuine."

I kind of agree. Japanese reactors do not use feet or retarded Fahrenheit scale. If you write a scientific article, use a proper scale and SI standard of measurements in order to be taken seriously (hint, hint, nudge, nudge).
