Answer Details

The correct order of processes for generating electricity in a nuclear reactor 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. This is because in a nuclear reactor, the heat energy is produced by the nuclear fission reactions occurring within the fuel rods. This heat energy is then used to heat up water, which is circulated through the reactor core to remove the heat energy. This is the second process (ii) mentioned in the options. The hot water then passes through a heat exchanger, which is the fourth process (iv) mentioned in the options. The heat exchanger uses the hot water to produce steam, which drives the turbines. This is the first process (i) mentioned in the options. Finally, the turbines generate electricity by rotating a generator, which is the third process (iii) mentioned in the options. Therefore, the correct order of processes is ii, iv, i, and iii.
