Correct Answer - Option 4 : Nuclear power plant
Comparison of Power Plant:
| Item |
Nuclear Power Plant |
Gas & Diesel Power Plant |
Steam Power Plant |
| Site |
These plants are located away from thickly populated areas to avoid radio-active pollution |
Such plants can be located at any place because they require less space and a small quantity of water. |
Such plants are located at a place where a supply of water and coal is available, transportation facilities are adequate |
| Initial cost |
The initial cost is the highest because of the huge investment in building a nuclear reactor. |
The initial cost is less as compared to other plants. |
The initial cost is lower than those of hydroelectric and nuclear power plants. |
| Operating Cost |
Except for the hydroelectric plant, it has the minimum running cost because a small amount of fuel can produce a relatively large amount of power |
Highest among all plants because of the high price of diesel. |
Higher than hydroelectric and nuclear plants because of the re- requirement of the huge amount of coal. |
| Cost of fuel transportation |
Less clean than hydroelectric and diesel power plants. |
Higher than hydro and nuclear power plants |
Maximum because a huge amount of coal is transported to the plant site. |
| Overall efficiency |
More efficient than a steam power station |
More efficient than a steam power station. Efficiency is about 35%. |
Least efficient. Overall efficiency is about 25%. |
| Standby losses |
Fewer standby losses. |
Fewer standby losses. |
Maximum as the boiler remains in operation even when the turbine is not working. |
From the above concept, it is clear that the Nuclear power plant has a high initial cost.
