Question

Which of the following is an advantage, nuclear fission has over fossil fuels?
A) Unlimited supply of fuel
B) Less radioactive waste
C) Fewer building expenses
D) Less released carbon dioxide

Answer 1

Hint: Any material that may be made to react with other substances to release energy as thermal energy or to be used for work is referred to as a fuel. The use of nuclear reactions to generate energy is known as nuclear power. Nuclear decay, nuclear fusion, and nuclear fission reactions are all sources of nuclear energy.

Complete answer:
Fossil fuel is the fuel that is created by natural processes, such as the anaerobic decomposition of buried dead creatures, and contains organic molecules that were formed during ancient photosynthesis and release energy when burned. These species and the fossil fuels they produce are often millions of years old, if not more than 650 million years old. They are inexpensive. The usage of fossil fuels has a significant negative impact on the environment. The annual carbon dioxide emissions from fossil fuel combustion are estimated to be over 35 billion tonnes.

The breaking of an atom's nucleus into two or more smaller nuclei is known as nuclear fission. Even by the intense standards of radioactive decay, the fission process frequently produces gamma photons and releases a considerable quantity of energy. The nuclear waste discharged by the power plant is highly radioactive and dangerous to all living things. These plants have a high risk of contaminating water, causing severe diseases and death in living things. The latest technologies and safety precautions required to run a nuclear power station necessitate a significant financial commitment.

Unlike fossil fuels, which cause significant environmental damage, nuclear fission produces energy without releasing greenhouse gases into the atmosphere, reducing the consequences of global warming and even helping to combat pollution.

Therefore the correct answer is option D i.e, Less released carbon dioxide.

Note: When particulates and other pollutants from fossil fuel combustion are inhaled, they cause illness and death. Premature death, acute respiratory disease, worsened asthma, chronic bronchitis, and impaired lung function are among the health impacts. Every year, 7 million people die as a result of air pollution around the world.
