Choose the three main components of a nuclear fission reactor from the following list:
i.The fuel elements
ii.The turbine
iii.The generator
iv.The control rods
v.The moderator
vi.The condenser

Question

Quizplus · Accepted Answer

The fuel elements (i) contain the radioactive material used to initiate the fission reaction. The control rods (iv) are used to regulate the reaction and slow down or speed up the rate of fission. The moderator (v) is used to slow down the neutrons produced in the reaction to ensure that they are absorbed by the fuel elements, rather than passing through the reactor unabsorbed. The turbine (ii), generator (iii), and condenser (vi) are all components of the power conversion system, which is used to generate electricity from the heat produced by the fission reaction. However, the three main components that are directly involved in the fission reaction are the fuel elements, control rods, and moderator. Therefore, the best choice is B.
