In boiling water reactor, moderator is
A. Coolant itself

B. Ferrite rod

C. Graphite rod

D. Liquid sodium metal$\mathrm{.}$

$32.$ In fast breeder react or any type of moderator can be used graphite is used as the moderator heavy water is used as the moderator may or may not be used moderator is dispensed with$\mathrm{.}\mathrm{}$

$33.$ In nuclear fission the original elements change into completely different elements the electrons of the element change the molecules rearrange themselves to form other molecules none of the above. None$\mathrm{}$

$34.$ In nuclear fission each neutron that causes fission releases no new neutron at least one new neutron one new neutron more than one new neutrons many$-$fold neutrons$\mathrm{.}\mathrm{}$

$35.$ In order to have constant claim reaction to produce a constant rate of heat output, the value of ratio of the number of neutrons in one generation to the number of neutrons in the immediately preceding generation must be

greater than $1\mathrm{.}0$

$$less than $1\mathrm{.}0$

$$equal to zero

equal to $1\mathrm{.}0$

equal to infinity
