Term
| How does a Nuclear Reactor work? |
|
Definition
1. The fossil fuel is burnt to convert its stored chemical energy into heat (thermal) energy.
2. The heat energy is used to heat water to produce steam.
3. The steam turns a turbine converting heat energy into kinetic energy.
4. The turbine is conected to a generator which transfers kinetic energy into electrical energy. |
