It's worth recalling that a coal plant burns 1.1 pounds of coal per kilowatt hour. Considering that a nuclear plant may produce 5 tera watt hours per year this translates to 2.5 million tons of coal burned per year for equivalent coal generation capacity. Uranium rich coals with concentrations above 200 mg/KG are used in resource extraction around the world. Our hypothetical plant burning this coal would release the equivalent of 500 tons of uranium. In practice it's estimated that Chinese coal plants emit 62 tons of uranium into the atmosphere per year, however this estimate critically depends on the quantity of uranium in the coal - one plant in china was estimated to emit 3 tons of uranium into the atmosphere. https://www.mdpi.com/2075-163X/7/12/239/htm https://www.mdpi.com/2075-163X/7/12/239/htm Note that 3 tons out of 2.5 million is not concentrated enough to run a nuclear power plant - but is producing greater emissions than our plant.
