What are the disadvantages of nuclear energy?

Answer: The nucleus, or core, of an atom, is where nuclear energy is found. Once captured, this energy can be used to generate electricity by causing nuclear fission in a reactor by either nuclear fusion or nuclear fission, two different types of atomic reactions. 

Disadvantages of nuclear energy include –

1. Radioactive waste – Nuclear energy production doesn’t produce any emissions, but it does produce radioactive waste, which needs to be safely kept to prevent environmental pollution. Radiation is safe in small doses, but the radioactive waste left over following nuclear energy production is quite deadly.
2. Limited fuel supply – A renewable energy source is not nuclear energy. Although it is currently abundant, uranium has a finite supply. The possibility that uranium will ultimately run out exists even though it is not a fossil fuel. Uranium must be mined, synthesised, and then activated in order to provide energy; in contrast, renewable energy sources like solar and wind have an endless supply. This procedure is rather pricey.
3. High water use – Nuclear power plants need a lot of water for energy production.In order to generate nuclear power in 2015, the United States used 320 billion gallons of water. That is more water than is used in the processing of coal. This high water usage could become unsustainable when water becomes more scarce, particularly in light of climate change.
4. Impact on the environment – It is necessary to mine uranium in order to create nuclear energy. Any type of mining has a detrimental effect on the neighbourhood. Arsenic and radon are particularly known to be released during uranium mining. Those who live close to uranium mines have suffered serious health effects as a result of this.
