Oh, where do I start. This is pure misinformation, and I wish people would actually consider the worse case.. Which looks a lot like Chernobyl, but even then its massively overstated. Yes, its true you can detect isotopes from an accident like that (which was a hydrogen explosion) for a very long time, but the way this works, is that isotopes with very long half lives, are basically not dangerous. AKA, if the half life of something is a couple hundred years, its not going to be decaying in your body. The chemical properties are going to have far worse effects. (AKA think about all the lead we blew into the air in every major metropolitan area). Things like Iodine-131, are what you have to worry about, but the half life is roughly 8 days. So its gone in a year. (and in fact its used as a cancer treatment, so...). Even then, if you compare the atmospheric effects of Chernobyl, they are orders of magnitude less than the atmospheric testing performed by the USA and the Soviets. Which can be detected in every living thing on the planet. So, 1: Managing to accumulate enough hydrogen for an explosion is something that modern designs avoid, thereby making it basically impossible. 2: Even if you manage to blow up, its actually not that dangerous outside of a very limited area because a couple KG of radioactive elements quickly get to the parts per billion levels of concentration, which can only be re-concentrated by biological processes, which itself is something fairly easy to detect. 3: When Chernobyl melted down, the other reactors at the plant continued to operate for another roughly two decades, and there has been continuous people living and working in the direct area. So, given the track record of the existing plants, if the entire worlds power came from them, and you had a Chernobyl level event every decade, it would still be an order of magnitude safer than solar/wind, which kills people from falling off roofs and towers. Never mind, that its 2020, and we have computers, which can monitor and apply fail safes long before humans sitting in a control room need to react if someone designed a plant which aren't mechanically impossible to meltdown. None of these designs from 50 years ago would be built today, for the same reasons we wouldn't build computers with discrete logic. Science and technology have advanced, and there isn't a need. We can build completely safe plants, where the largest problem is worrying about asteroid impacts. So, knock off the fear mongering.
