1,664 views 4 weeks ago

The explosion of Unit 3 was significantly different than that of Unit 1. Only the explosion of Unit 3 had vertical magnitude and a mushroom cloud. Here I outline the steam-explosion model, which is isomorphic to the explosion of Unit 3, mapping directly onto its physical phenomena.

Thorium, Safer Nuclear Energy Play

I've not studied thorium enough to be able to claim an informed opinion, but a number of credible experts believe it's a safer nuclear fuel than uranium without the potential for catastrophic meltdowns present with uranium-based fuels. Its advocates contend that because thorium does not produce plutonium as a byproduct, which is needed to produce nuclear weapons, nuclear energy was steered by governments to uranium as the energy substrate.

U.S. Radioactive Rain is Natural Radon Washout Play

Youtube is flooded with videos that falsely attribute radioactive rains in North America to Fukushima fallout. But in every case where the user tests their rain sample over time, a rapid decay to normal within a day or a few days at most is reported. That is the 'acid-test' for radon, which is normally washed out with rains. In contrast, nuclear fallout in rain would remain hot for years.
