In India, about ______ % of total power is generated by using nuclear energy.

  1. 2

  2. 3

  3. 4

  4. 6


Correct Option: B
Explanation:
3, India has a flourishing and largely indigenous nuclear power programme and expects to have $14.6 GWe$  nuclear capacity on line by 2024 and$ 63 GWe$ by 2032. It aims to supply 25% of electricity from nuclear power by 2050.
Because India is outside the Nuclear Non-Proliferation Treaty due to its weapons programme, it was for 34 years largely excluded from trade in nuclear plant or materials, which has hampered its development of civil nuclear energy until 2009.
Due to earlier trade bans and lack of indigenous uranium, India has uniquely been developing a nuclear fuel cycle to exploit its reserves of thorium.
Since 2010, a fundamental incompatibility between India’s civil liability law and international conventions limits foreign technology provision.

The energy of a neutron released during a fission process should be reduced by about ______ part to convert it into a thermal neutron.

  1. $10^8$

  2. $10^9$

  3. $10^6$

  4. $10^2$


Correct Option: A
Explanation:
 $10^8$
Thermal neutron, any free neutron (one that is not bound within an atomic nucleus) that has an average energy of motion (kinetic energy) corresponding to the average energy of the particles of the ambient materials. Relatively slow and of low energy, thermal neutrons exhibit properties, such as large cross sections in fission, that make them desirable in certain chain-reaction applications. Furthermore, the long de Broglie wavelengths of thermal neutrons make them valuable for certain applications of neutron optics. Thermal neutrons are produced by slowing down more energetic neutrons in a substance called a moderator after they have been ejected from atomic nuclei during nuclear reactions such as fission.

Which of the following is an optional form of energy ?

  1. Natural gas

  2. Hydrogen

  3. Petroleum

  4. Geothermal energy


Correct Option: D
Explanation:

Geothermal energy.

Geothermal energy is the heat from the Earth. It is clean and sustainable. Resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the Earth's surface, and down even deeper to the extremely high temperatures of molten rock called magma.

How much energy is produced when two$ _1H^2$ nuclei fuse to produce $ _1H^3$ and $ _1H^1$ ?

  1. 1.0 MeV

  2. 4.0 MeV

  3. 1000 MeV

  4. 3.3 MeV


Correct Option: B
Explanation:
$4.0 MeV$
Energy released in most nuclear reactions is much larger than in chemical reactions, because the binding energy that holds a nucleus together is far greater than the energy that holds electrons to a nucleus. For example, the ionization energy gained by adding an electron to a hydrogen nucleus is $13.6 eV$—less than one-millionth of the $17.6 MeV$ released in the deuterium–tritium (D–T) reaction.  The complete conversion of one gram of matter would release $9\times10^{13}$ joules of energy. Fusion reactions have an energy density many times greater than nuclear fission; the reactions produce far greater energy per unit of mass even though individual fission reactions are generally much more energetic than individual fusion ones, which are themselves millions of times more energetic than chemical reactions. Only direct conversion of mass into energy, such as that caused by the annihilatory collision of matter and antimatter, is more energetic per unit of mass than nuclear fusion.
