There IS a rebranding going on. Some people, including environmentalists, are advocating nuclear power because it is "clean" meaning it does not produce climate changing greenhouse gasses. Somehow they are forgetting the high level radioactive waste produced by nuclear power plants. That waste stays lethally dangerous for TENS OF THOUSANDS of years. No one has come anywhere near a plan to keep nuclear waste safely contained without humans watching over it. That ain't gonna happen for millennia. Until someone comes up with a way to utilize shorter half life radioisotopes or some, presently magical, way of isolating the high level waste, "clean" nuclear power is just dangerously wishful thinking.
From the US Nuclear Regulatory Agency:
Radioactive isotopes eventually decay, or disintegrate, to harmless materials. Some isotopes decay in hours or even minutes, but others decay very slowly. Strontium-90 and cesium-137 have half-lives of about 30 years (half the radioactivity will decay in 30 years). Plutonium-239 has a half-life of 24,000 years.
High-level wastes are hazardous because they produce fatal radiation doses during short periods of direct exposure. For example, 10 years after removal from a reactor, the surface dose rate for a typical spent fuel assembly exceeds 10,000 rem/hour – far greater than the fatal whole-body dose for humans of about 500 rem received all at once. If isotopes from these high-level wastes get into groundwater or rivers, they may enter food chains. The dose produced through this indirect exposure would be much smaller than a direct-exposure dose, but a much larger population could be exposed.
Fear of nuclear energy has made it harder to stand up to dictators and slow down global warming. Is it time for a rebrand?
