Question
Explain with diagram step-by-step energy conversion in Nuclear Power Plant.

Solution
Nuclear power plants consist of nuclear reactors. These reactors use uranium rods as fuel and heat is generated by the process of nuclear fission. Neutrons smash into the nucleus of the uranium atoms, which roughly split into half and release energy in the form of heat. Carbon dioxide gas is pumped through the reactor to take the heat away. The hot gas then heats water to form steam. This steam drives the turbines of generators to produce electricity. Thus, the steps of energy conversion are:
Nuclear energy→Thermal energy →kinetic energy in steam→kinetic enegry in turbine
