    Consider the following statements.
    1. The hydrogen bomb is based on thermonuclear fission reaction.
    2. The fundamental physics of the fission chain reaction in a nuclear weapon is quite different to the physics of a controlled nuclear reactor. Also, the two types of devices are engineered differently.
    3. No industrialised nation has been able to meet even one-fourth of its total demand of energy from nuclear reactors.
    Which of the statements] given above is/are correct?

    A)  1 and 2           

    B)  Only 3            

    C)  All of these                   

    D)  None of these

    Correct Answer: D

    Solution :

    [d] The hydrogen bomb is based on thermonuclear fusion reaction. A nuclear bomb based on the fission of uranium or plutonium is placed at the core of the hydrogen bomb. This nuclear bomb is embedded in a substance which contains deuterium and lithium. When the nuclear bomb (based on fission) is detonated, the temperature of this substance is raised to 10'K in a few microseconds. The high temperature generates sufficient energy for the light nuclei to fuse and a devastating amount of energy is released.
