Junior high school history involves wars that include both Chinese and foreign ones

Nuclear power generation profits.

The biggest advantage of nuclear power generation is what we know, the energy is huge. It produces a large amount of energy with a small amount of nuclear fuel. One tonne of low-enriched uranium has the energy equivalent to about 50,000 tonnes of heavy oil. In addition to this, the advantages of nuclear power generation are as follows:

1. Low pollution. Nuclear power is generated by using the heat energy released by nuclear fission in a nuclear reactor.

Nuclear power generation does not emit huge amounts of pollutants into the atmosphere and does not cause air pollution. In particular, compared to thermal power plants, nuclear power generation does not contribute to the global warming effect"The culprit"--Carbon dioxide. Nuclear power plants are equipped with layers of barriers, and basically do not emit substances that pollute the environment, and even radioactive pollution is much less than that of coal-fired power plants.

2. In terms of fuel resources, the earth is expected to be the first. The world has relatively rich nuclear resources, nuclear fuel includes uranium, thorium, deuterium, lithium, boron, etc., and the global uranium reserves are about 4.17 million tons. The nuclear fuel resources available for development on the earth can provide more than 100,000 times more energy than fossil fuels.

3. Convenient transportation and low cost. Nuclear fuel is millions of times more energy dense than fossil fuels, so the fuel used in nuclear power plants is small and easy to transport and store. For example, a nuclear power plant uses 80 tons of nuclear fuel per year, which can be carried in just two standard containers.

If it is replaced with coal, it will require 5.15 million tons, and 705 trucks will need to be transported by 20 tons per day.

Nuclear power generation is a disadvantage.

1. Nuclear waste treatment needs to be rigorous. Used nuclear fuel, although it does not occupy a large volume, must be handled carefully because it is radioactive. If not handled properly, it is likely to have a fatal impact on environmental life.

The radioactivity of nuclear waste cannot be eliminated by ordinary physical, chemical and biological methods, but can only be reduced by the decay of the radionuclide itself. When the radiation emitted by nuclear waste passes through the substance, it is ionized and excited, causing radiation damage to living organisms.

At present, there are mainly ways to deal with high-level radioactive nuclear waste in the world"Reprocessing"with"Direct disposal"Both. "Reprocessing"Mainly from nuclear waste, nuclear materials that can be reused; "Direct disposal"It refers to the underground burial of highly radioactive waste, which generally goes through three stages: cooling, dry storage, and final disposal. The United States, for example, has been using underground burials to dispose of nuclear waste.

In the Yucca Mountains of northern Nevada, 10,000 tanks of 30 to 80 tons have been buried in tunnels hundreds of metres underground.

3. Nuclear power generation is considered risky. Nuclear fission must be controlled by a person through a device. If it gets out of control, fission energy will not only be unable to generate electricity, but will also cause disaster.

There have been several nuclear accidents around the world, causing great harm to the ecology and people. Some environmentalists argue that nuclear power is not a safe source of energy compared to other renewable energy sources.
