Both nuclear and coal use heat to boil water and produce steam to turn a turbine. But, Nuclear energy uses radioactive elements to produce heat during nuclear fission, while coal energy burns coal to produce heat. (Differences 2012)
They also differ in energy density: for nuclear energy, a uranium pellet the size of a pencil eraser could contain as much energy as a ton of coal. This allows Nuclear power plants to produce more energy efficiently.
Most of the consumption of fossil fuels is done through road transport, not to produce energy.
The accidents that can occur can’t always be dealt with quickly, or at all.
Nuclear waste takes years before the radioactivity expires.
The construction of a nuclear plant is incredibly expensive, and this raises the price of the electricity produced.
Nuclear reactors have an expiration date. When they can’t be used anymore, it’s expensive, dangerous, and takes a long time to shut down the plant.
They require reliance on other countries, since not every county has access to uranium and/or nuclear technology, so they rely on other countries for information.
More nuclear power used means less use of fossil fuels to produce energy. The decrease of fossil fuels lowers greenhouse gas emissions, and helps to improve global warming and climate change.
Less fuel means more energy, which saves on the amount of raw materials extracted and handled.
The cost of nuclear fuel is only 20% of the cost of producing the power
The production of electricity is almost continuous, producing energy 90% of the time
It’s doesn’t rely on natural occurrences, like solar or wind power do, so it can coincide with raising and lowering demand.(Advantages 2017)
