71. Suggest the design of nuclear reactor.
Suggestion Explanation
Use uranium-235 Use as nuclear fuel
Nuclear fission A lot of heat will produce
Boron or Cadmium rod To control the rate of nuclear
use as control rods fission and to stop the radiation
Use moderator To slow the motion of neutron to
(graphite) the best reaction rate. So the rate of
nuclear fission can be controlled
Build thick concrete Lead or thick concrete wall can
wall prevent the escape of radioactive
rays
Carbon dioxide or To remove heat of reaction for
water is use as cooling turbine generator. This produce
agent steam as heat carrier
Use steam To turn the turbine and able to
generate current
