Nuclear power is a clean energy source and does not emit large amounts of carbon dioxide, sulfur and nitrogen pollutants into the atmosphere like thermal power generation.
The uranium fuel used in the production of nuclear energy has no other purpose than the production of electricity. The coal and oil needed to produce thermal energy are non-renewable energy sources, and the more they are used, the less they are used. .
The fuel used in nuclear power plants is small and easy to transport and store, while thermal power generation requires a huge transport volume.
Fuel costs represent a smaller proportion of the cost of nuclear power generation. The cost of nuclear power generation is less sensitive to the impact of the international economic situation, so the cost of electricity production is more stable than that of nuclear energy production. other methods of energy production.
However, the consequences of a serious accident in nuclear power generation are unimaginable, and improving the safety of nuclear power generation is a top priority.
What are the advantages of nuclear power plants over thermal power plants?
The principles are different: nuclear power uses atomic energy, which is generated by fission reactions nuclear to produce energy; Thermal power generation is generated by burning coal or fuel oil to produce electricity.
Safety requirements are different: nuclear fuel and its fission products used in nuclear energy production are radioactive, so there are special requirements for operation and radiation protection. In addition, spent nuclear fuel (combustible worn) and decommissioned. the installations are also radioactive and their management requires enormous costs; Conventional thermal energy does not contain nuclear radiation.
In addition, nuclear power does not produce harmful gases such as carbon dioxide and sulfur dioxide; while conventional thermal power produces a large amount of greenhouse gas emissions and requires additional desulfurization facilities.
Advantages:
1. Nuclear power generation does not emit huge amounts of pollutants into the atmosphere like fossil fuel-based power generation, so nuclear power generation does not cause air pollution p>
pollute.
2. Nuclear power generation does not produce carbon dioxide which worsens the Earth's greenhouse effect.
3. Uranium fuel used in nuclear power production has no other purposethan electricity production.
4. The energy density of nuclear fuel is millions of times greater than that of fossil fuels. Therefore, the fuel used in nuclear power plants is small and easy to transport and store.
>A 1,000-meter nuclear power plant A 10,000-watt nuclear power plant requires only 30 tons of fuel uranium per year, which can be transported by plane in a single flight.
5. Fuel costs represent a smaller proportion of the cost of nuclear power generation. The cost of nuclear power generation is less sensitive to the impact of the international economic situation.
the cost of electricity production is lower than other electricity production costs. The method is stable.
Disadvantages:
1. Nuclear power plants will produce high and low level radioactive waste, or nuclear fuelworn out, although the volume is not large,
The write-offs must therefore be treated with caution and considerable political problems must be faced.
2. The thermal efficiency of nuclear power plants is low, so they emit more waste heat into the environment than ordinary fossil fuel power plants. Therefore, thermal pollution from nuclear power plants
3. The investment cost of nuclear power plants is too high, the financial risk of power companies is higher.
4. Nuclear power plants are less suited to on-peak and off-peak operation with load.
5. The construction of nuclear power plants is more likely to cause political differences and conflicts.
6. There is a large amount of radioactive materials in the reactor of the nuclear power plant if they are released into the surroundingsexternal exposure during an accident, it will harm the ecology and people. /p>
