As we remember the 1986 Chernobyl tragedy, it's worth also reminding that ~400 other #nuclear reactors worldwide continue operate uninterrupted for the last half century providing stable and clean electricity.
Three remaining Chernobyl reactors continued to operate safely to 2000.Even after Chernobyl closure Ukraine's energy sector continues to produce electricity at relatively low CO2 intensity thanks to #nuclear plants - today it's 240 gCO2eq/kWh while Germany is at... 230.
So what we're really concerned about is high-level waste so stuff that was actually inside the reactor. Again, I have just recently discovered that 95% of that is recycled back into nuclear fuel (so called MOX).
This movie from La Hague reprocessing plant (France) goes into great detail on how it works https://www.youtube.com/watch?v=V0UJSlKIy8g
So the remaining amounts are absolutely tiny, especially if you compare with other sources of energy.
