Answer:
D) all of the above
Explanation:
The energy generation processes of a normal nuclear reactor has multiphase processes. First of all, the reactor core utilize nuclear fission reactions which produces a lot of heat energy. This heat is then used to heat water, converting it into steam as indicated in (A). The high-pressure steam is then taken to a turbine (B) with the aim of providing kinetic energy to the blades of the turbine. The spinning turbine then drives a generator; as it turns, electricity is produced (C). Hence, heating water to form a steam is part of energy out put process in a nuclear reactor and driving steam to a turbine to spin and generate electricity all the stages (D) are part of energy output process.
Therefore, the correct answer option is D).
