Steam from the heat of the reactor.
Electrical energy
Nuclear energy is converted to electrical energy in a nuclear power plant.
As atoms break and forming elements having more binding energy per nucleon heat energy is released. Hence nuclear energy gets changed into heat energy Right from heat energy mechanical energy is produced This mechanical energy in the presence of magnetic field gets changed into electrical energy. So nuclear ---> heat ---> mechanical ----> electrical
A power plant generator
A toaster converts electrical energy into thermal energy. Some of that electrical energy may have come from a nuclear power plant.
Thermal energy
Electrical energy
A nuclear power plant produces electrical (electromagnetic) energy, or what most call electricity or electric power.
A car engine, a coal or petroleum power plant, a nuclear reactor.
You can transform thermal energy to electrical energy in a power plant, chemical energy to mechanical energy in an internal combustion engine, or nuclear energy into thermal energy in a nuclear reactor. These are just three examples.
