As an aside, try to imagine the effort involved in acquiring the billions of tons of coal that are burned globally each year. How can this inefficient practice be cost-effective? The only reason that the energy produced per dollar by way of coal burning is similar to that by way of nuclear reactor is because the coal miners are not justly compensated for their work.
While the production of nuclear power is not without risk, it must be noted that mining coal is also an extremely risky task. Countless miners die on the job each year so that our light bulbs may remain powered.
