In a nuclear reactor,boron rods are used as ...... .

Fast neutrons can be easily slowed down by:

In a nuclear fusion process,a certain mass of hydrogen is converted into helium,resulting in a mass defect of $0.02866 \, u$. The energy released per $1 \, u$ of mass formed is ......... $MeV$. (Given $1 \, u = 931 \, MeV$)

Which of the following is the best neutron moderator compared to all others?

The energy released by the fission of one uranium atom is $200 MeV$. The number of fissions per second required to produce $3.2 W$ of power is (Take $1 eV = 1.6 \times 10^{-19} J$).

In a nuclear reactor,the function of the moderator is to decrease
