Comment Increase in radioactive emissions as well (Score 1) 155
Note that shutting down all nuclear plants would also have the counterintuitive effect of releasing more radioactives into the environment as well.
Fossil fuels don't burn clean, as they are often contaminated with other minerals and are only refined enough to where they can burn (and reducing can release emissions of it's own). While this is clearly true for coal it also applies to oil to some degree. For this reasons, coal power plant emissions are several orders of magnitude more radioactive than you get from nuclear power plants due to uranium and other ores that are mixed in. A drop in nuclear usage is likely to be compensated by an increase in coal or other fossil fuels.
Even if the slack in electricity production is taken up by renewables, the radioactives pulled up from mining the materials for constructing solar panels, batteries, or wind turbines are likely to be left in contained in tailings piles that will be washed into rivers as opposed to the strict containment nuclear facilities need to apply to their radioactives.
