Hydrogen nuclei fusions occur naturally in the core of the
Sun at about 15.6 million Kelvin and 250 billion times the
Earth’s atmospheric pressure. Over 560 million tons of
hydrogen fuse to become helium in an instant. The nuclear
energy released in the fusion reaction is the source of light
and heat energy for the Sun and stars in the outer space.
Nowadays, scientists have succeeded in designing
small-sized Tokamak fusion reactors in the laboratory. The
heat produced by the nuclear reaction (nuclear fusion) is
used to generate electrical power. If such technology can be
commercialised, the dependence on the consumption of fuel
sources like petroleum and coal to generate electrical power
http://bit.ly/ can be overcome in the future.

Importance of the Chapter

Knowledge of nuclear physics allows engineers and scientists
to design safer nuclear power plants to generate electrical
energy. This knowledge can also be applied to manage
the nuclear plant waste carefully and efficiently to prevent
environmental pollution and to ensure the well-being of
the ecosystem of the earth. Such advancements will bring
about the sustainability of energy resources and improve the
productivity of our country.

Futuristic Lens

Research on the construction of nuclear fusion reactors to
meet the increasing demand for electrical power generation
may be achieved in the future. Energy from nuclear fusion
is an alternative energy that is capable of reducing the
consumption of petroleum and coal. This alternative energy
is more efficient, has zero carbon footprint and has minimal
http://bit.ly/ impact on our earth’s ecosystem if it is well coordinated.
