Answer :
Final answer:
The average 1000 megawatt coal power plant requires more than 100 rail cars of coal per day, while a nuclear power plant uses about 40 tons of uranium-235 per year. Nuclear power plants are more fuel-efficient, with one ton of uranium-235 producing considerably more energy than a similar mass of coal due to different energy producing methods.
Explanation:
According to information typically accepted in the physics and energy analytical studies, option A is the factual and correct statement while option B is not. A 1000 megawatt coal-fired power plant requires more than 100 rail cars of coal per day to function at standard power generation levels. On the other hand, a nuclear power plant of the same capacity would only consume around 40 tons of uranium-235 in a typical year. Using core principles of thermodynamics and nuclear physics, nuclear power plants are considerably more fuel-efficient compared to those that use fossil fuels.
The efficacy difference lies in the method each power plant uses to produce electricity. Coal plants convert heat energy from burning coals into steam. This steam then moves turbines which generate electricity. In nuclear plants, energy comes from fission of uranium-235, efficient and able to produce massive amounts of energy from a small mass of uranium due to E=mc^2, Einstein's well-known equation.
