In a nuclear reactor, electricity can be generated through the following processes. Arrange the processes in the correct order. i. The steam is used to drive turbines. ii. The heat energy released is removed by passing water through the reactor. iii. The turbines in turn generate electricity. iv. The water then passes through some form of heat exchanger to produce steam
-
ii, iv, i and iii
- i, ii, iii and iv
- iii, i, iv and ii
- iv, i, iii and ii
The correct answer is: A
Explanation
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
