Hydrogen bomb is more powerful than atom bomb due to the fast freeze of very large amount of energy in the thermo nuclear reactions among the nuclei of hydrogen isotopes. If the requirement of sufficient high temperature for hydrogen bomb were fulfilled in the atmosphere ...

The thermal nuclear reactions among nuclei of hydrogen isotopes like deuterium and tritium serve as sources of energy on earth crust. These type of nuclei occur more rapidly so they can provide us a large amount of energy through thermonuclear reactions provided temperature range must ...

The energy production in the sun and the star could be explained on the basis of carbon cycle by means of which hydrogen is converted into helium. 6C12 act as a catalyst in these reactions. It undergo changes but is not used up since it ...

It is a process of formation of heavier and bigger nucleus by the combination of various lighter and smaller nucleus. This process is called nuclear fusion. This process can take place by falling of highly accelerated protons and deuterons in the nuclei of lighter elements. ...

As we know 92U238 is bigger in size so it will not breakup unless the energy of bombarding neutrons is more than 1.2 MeV. Such neutrons are called fast neutrons. On the other hand, U235 can be easily fissioned by slow neutrons which are called ...

Various type of radioactive material like plutonium can be used as a fissionable material. However, ordinary uranium consists only of about 0.7 percent of U235 and it is extremely difficult to isolate U235 from the other isotopes present in the ordinary uranium. As a result ...

The large amount of energy is released from various nuclear fission processes. This release of energy can be occurred in two ways: 1. In a controlled manner 2. In an uncontrolled manner. UNCONTROLLED RELEASE OF FISSION ENERGY: In this method the sub critical amount of a fissionable material is suddenly ...

These are the materials which are used to slow down the speed of fast moving neutrons in a nuclear fission process. It is observed that the fast moving neutrons are not captured by the nuclei of U235 and as a result no fission of U235 ...
