Wastewater and exhaust gases released from nuclear power plants contain impurities such as compounds. As for radioactivity, there will certainly be some when it is not treated. When released into the environment, these harmful impurities must be removed and discharged only afterwards. meeting standards
< p>In the reactor, the neutrons produced by nuclear fission seem to have a certain impact on these impurities. For example, cobalt 59 transforms into cobalt 60, which is radioactiveWhat. Is the water soft in power plants? Is it toxic?
Wastewater from nuclear power plants contains radiation.
Wastewater discharged from nuclear power plants is mainly divided into two types. One is cooling water, which is very large and has the same function as the cooling tower water of ordinary thermal power plants. centerelectric ones, but is used for cooling. Those used do not come into contact with radioactive materials, so radioactive materials from the nuclear power plant have not been removed. The other concerns wastewater, which is in very small quantities. According to national regulations, this wastewater must undergo special treatment to bring its radioactivity level below a certain limit, so that it does not affect the environment.
The natural environment itself is also radioactive. If the radioactivity of the effluent is equivalent to the radioactivity of the natural environment, there will be no impact. But even after treatment, wastewater from nuclear power plants can still contain radioactive materials.
The working principle of nuclear power plants
Burning water is basically energy conversion, and other energy is converted into energy thermal water. THENuclear power plants use nuclear energy to "boil water" and are carried out in reactors. This step is much more complicated than using boilers in thermal power plants to "boil water" because it involves nuclear fission reactions.
As we all know, thermal power plants use coal, oil or natural gas to generate electricity, hydroelectric power plants use hydropower to generate electricity, and power plants Nuclear power uses the fission energy of atomic nuclei to produce electricity. . At present, more than 60% of the world's nuclear power plants are pressurized water reactor nuclear power plants, which mainly consist of reactors, steam generators, turbines, generators and related system equipment .
Water that contains no or less calcium and calcium compoundshe soluble magnesium is called fresh water. Soft water is less likely to scum with soap, while hard water is the opposite. Natural fresh water generally refers to river water, river water and lake water (freshwater lake). Soft water can completely remove dirt from skin cells, delay skin aging, and make the skin after cleaning without tightness and with delicate luster. Since soft water is rich in organic minerals and has strong detergent power, only a small amount of makeup remover can achieve 100% makeup removal effect. Therefore, fresh water is a necessity for beauty lovers. Soft water can be used for regular bathing, which can help you relieve dry skin, psoriasis and dandruff, and restore normal skin elasticity. Skin inflammation is caused by soap, detergents, friction, wood, leather, asirritating seasons, bacteria, dry air, etc. If you have eczema or cracks on your hands and feet, washing them frequently with fresh water can lead to eczema. and the cracks can be healed. Give yourself soft and shiny hands and feet.
Fresh water can also effectively inhibit fungi. In case of skin trauma, frostbite, burns or other accidents, wash first with fresh water. After cleaning the affected area, soak absorbent cotton, gauze, towel, etc. with fresh water and gently rub the affected area, which can quickly heal the wound and make the edema caused by burns disappear immediately. regeneration of cellular tissues. Washing your hair frequently with fresh water can make your hair soft and sleek, eliminate dandruff and relieve itching, protect it from dryness and astringency, and make your hair naturally briillants.
