To arrange the processes in the correct order for generating electricity in a nuclear reactor, let's break down the steps involved:
1. Heat Generation: The nuclear reaction generates heat.
2. Heat Removal: This heat is removed by passing water through the reactor.
3. Steam Production: The heated water then passes through a heat exchanger to produce steam.
4. Turbine Operation: The steam drives turbines.
5. Electricity Generation: The turbines generate electricity
Therefore, the correct order is:
ii: The heat energy released is removed by passing water through the reactor.
iv: The water then passes through some form of heat exchanger to produce steam.
i: The steam is used to drive turbines.
iii: The turbines in turn generate electricity
