Nuclear energy is renewable or non renewable resources?
Uranium is currently the most important nuclear fuel, 1 kilograms of uranium available energy equivalent to burning 2500 tons of high quality coal. However, the storage of uranium on land is not rich, and the distribution is very uneven. Only a few countries have limited uranium, the whole world is suitable for mining only 1 million tons, even with low grade uranium ore and its by-product uranium compounds, the total amount of not more than 5 million tons, according to consumption, enough mining for decades. But in the huge water body, it is rich in uranium resources. It is estimated that the number of dissolved uranium in seawater can reach 45 tons, equivalent to several times the total land reserves. If we can extract all the uranium in seawater, the fission energy can guarantee the energy needs of mankind for thousands of years. However, the concentration of uranium in seawater is very low, 1000 tons of seawater containing only 3 grams of uranium. Only uranium can be extracted from seawater before it can be used. And to extract uranium from seawater, technically speaking is a very difficult thing, need to deal with a large number of sea water, the technical process is very complex. However, many methods have been developed for the extraction of uranium from seawater, such as adsorption, coprecipitation, bubble separation, and algae concentration.
Nuclear energy is one of the most promising future sources of energy. There are two ways for people to develop nuclear energy: one is the fission of heavy elements, such as the fission of uranium; the other is the fusion of light elements, such as deuterium, tritium, lithium and so on. Heavy element fission technology has been applied in practice, and the light element fusion technology is also being actively studied. Whether it is the heavy element uranium, or light elements deuterium, tritium, in the ocean has a considerable amount of storage.
Nuclear (atomic energy) by nuclear reactions from nuclear energy released, with Albert Einstein's mass energy equation of E=mc - E=, m= energy, light quality, c=. Nuclear energy can be released through one of three nuclear reactions: 1, nuclear fission, heavier nuclear fission release binding energy. 2, nuclear fusion, the lighter nuclei together to release the binding energy. 3, nuclear decay, the spontaneous release of nuclear energy in the process of decay.
Nuclear energy is the energy of the nuclear ore, the ore belongs to the mineral resources, and the mineral resources belong to the non renewable resources.
