Thank you. I’ve seen this too. My knowledge of nuclear physics has grown 1000 times from what I used to know before our Fukushima incident. I was particularly interested in radioactivity of pellets and fuel bundles before fission and decay takes place, and what physical processes and nuclide creation occurs during a meltdown, and this information has been the best I’ve found in months. If you know of any similar scientific articles or papers, I would love to read them.
