Q16 | Fast breeder reactors do not

use molten sodium as coolant

use fast neutrons for fission

use th-232 as fissile fuel

convert fertile material to fissile material

Q17 | A boiling water reactor is the one, in which the

pressurised water is pumped into the core.

coolant water, after being heated in the reactor core, generates steam in a boiler

fuel and the coolant are thoroughly mixed to form a homogeneous solution

coolant water is allowed to boil in the core of the reactor

Q18 | Commercial power generation from fusion reactor is not yet possible, because

it is difficult to initiate fusion reaction

the fuel required (e.g. deuterium and tritium) is scarce

it is difficult to control fusion reaction

quantity of fuel required for initiating fusion reaction is prohibitively high

Q19 | Thermal shield is used in high powered nuclear reactors to

absorb the fast neutrons

protect the walls of the reactor from radiation damage

slow down the secondary neutrons

protect the fuel element from coming in contact with the coolant
