In a nuclear power plant
the heavy-metalic-electricity-producing machine
yes. this is because nuclear power plants use nuclear fusion
Nuclear fission produces heat energy that produces steam The steam spins the turbines that spins electric generators and hence producing electricity.

How big is the plant?
The largest nuclear energy producing plant in the world is located in Kashiwazaki and Kariwa, Japan. It is owned by the Tokyo Electric Power Company.
Yes, nuclear power plants produce electric power (electricity).
It's really just a matter of degree, all reactors produce some power. Those used in a power plant will produce perhaps 3000 to 5000 Megawatts thermal. Low power reactors producing a few kilowatts are used for experiments, teaching in universities, and for producing radioisotopes by irradiating samples, but reactors in this sort of power level would not be harnessed to produce electricity, the heat produced if large enough would be removed and rejected to the atmosphere or to a water cooling circuit. This makes them simple to operate and to start and stop as required.
The generation of electricity.
To produce electricity
Make electricity.
Because the power plant is the source of electricity
