1. The fuel of thermal power plants is coal, including various coals such as thermal coal, coke, lignite, etc. The fuel for nuclear power plants is the radioactive element uranium.
2. The cost of thermal power plants mainly corresponds to the cost of coal. With the current increase in domestic prices, the price of good thermal coal is basically around 500 yuan/ton, and the cost is relatively high. , while the cost of nuclear power plants The cost is uranium, which is much more expensive than coal, but it can operate continuously for more than a year after being recharged once, so it is simpler than the coal.
3. The pollution and fire points generated are mainly SO2, CO2 and ashes after the combustion of the coal. It has some impact on the air, while nuclear energy is mainly about radiation and the impact on water temperature.u after the cooling water is released into the sea. In comparison, nuclear power is relatively clean, at least it is invisible to the naked eye.
4. In terms of scale, general nuclear units like Qinshan Phase 1 are 1*300 MW, Phase 2 is 2*600 MW, Daya Bay units are 2*800 MW and Sanmen Nuclear Power Plant will begin construction. in 2009 This is a third generation nuclear reactor planned by the American company Westinghouse with a capacity of 6*1000 MW. It is expected to be the most advanced and largest unit in China.
5. As for the energy change process, thermal energy uses water vapor generated by burning coal to drive the turbine to operate. This is a process of chemical energy from coal - mechanical energy from turbine - electrical. energy. Nuclear energy is the process of chemical energy - mechanical energy - electrical energy of mnuclear raw materials. The principle is the same, only the fuel is different.
