I am a former nuclear opponent. I used to think that nuclear waste was glowing green like they show in the Simpsons and in the Doom 1 game. Once I had access to the Internet in this century, I learned better. Here are some sources of information that helped me understand the two oft-cited nuclear disasters better. The World Nuclear Energy write up on the Fukushima incident: [LINK] Some information on the Chernobyl incident: The infographics show: [LINK] [LINK] A lecture in the MIT Courseware on the incident: [VIDEO] This lecture is way more informative where the professor explains how the workers took the system beyond the rated capacity as part of a test. There have been many lessons learned, and the World Nuclear article linked above shares some of these. Here is a writeup of the Three Mile Island incident: [LINK] One regular complaint is the costs of nuclear energy. This is likely true in the US due to regulations that have not been revised for newer technology, but such high costs are cited around the world. Likewise, the amount of waste and the danger of the waste is not well understood either, and certainly lots of education is needed here. For e.g., most people do not know that the volume of waste is limited and that the same waste can be reused in reactors of other designs. I do believe that national ego issues get in the way of fixes. I believe that such ego issues got in the way of honest repairs (Fukushima) and timely action (Chernobyl). Certainly, nuclear inspecti

Understanding disasters like Chernobyl really puts into perspective how quickly things can go wrong with radioactive material. I found the following lecture does a great job outlining the Chernobyl disaster and potential impact of similar disasters, both from a meltdown perspective and understanding the impact of radiation.
