what are the risks of using nuclear energy?

Nuclear power plants are a potential target for terrorist operations. An attack could cause major explosions, putting population centers at risk, as well as ejecting dangerous radioactive material into the atmosphere and surrounding region.

All nuclear power plants use nuclear fission, and most nuclear power plants use uranium atoms. During nuclear fission, a neutron collides with a uranium atom and splits it, releasing a large amount of energy in the form of heat and radiation. More neutrons are also released when a uranium atom splits.

The evidence over six decades shows that nuclear power is a safe means of generating electricity. The risk of accidents in nuclear power plants is low and declining. The consequences of an accident or terrorist attack are minimal compared with other commonly accepted risks.

Other Non-renewable Energy Sources Nuclear energy is usually considered another non-renewable energy source. Although nuclear energy itself is a renewable energy source, the material used in nuclear power plants is not. Nuclear energy harvests the powerful energy in the nucleus, or core, of an atom.

But fusion reactors have other serious problems that also afflict today's fission reactors, including neutron radiation damage and radioactive waste, potential tritium release, the burden on coolant resources, outsize operating costs, and increased risks of nuclear weapons proliferation.

As radioactive material decays, or breaks down, the energy released into the environment has two ways of harming a body that is exposed to it, Higley said. It can directly kill cells, or it can cause mutations to DNA. If those mutations are not repaired, the cell may turn cancerous.

Types. Nuclear energy is defined by how it is propagated. Namely, there are three production methods for nuclear energy: radioactive decay, fusion and fission. All three of these nuclear energy-producing processes release particles, gamma rays, neutrinos or all three.

Advantages of nuclear power. The generation of electricity through nuclear energy reduces the amount of energy generated from fossil fuels (coal and oil). Less use of fossil fuels means lowering greenhouse gas emissions (CO2 and others). The cost of nuclear fuel (overall uranium) is 20% of the cost of energy generated.

Explanation: Solar energy leads to least environmental pollution in the process of its harnessing and utilization. In case of nuclear energy, the major concerns of pollution are while storage and disposal of spent fuels where there is always a risk of leakage of radiation.

The United States has more than 100 reactors, although it creates most of its electricity from fossil fuels and hydroelectric energy. Nations such as Lithuania, France, and Slovakia create almost all of their electricity from nuclear power plants. Uranium is the fuel most widely used to produce nuclear energy.

Nuclear Power Nuclear energy originates from the splitting of uranium atoms – a process called fission. This generates heat to produce steam, which is used by a turbine generator to generate electricity. Because nuclear power plants do not burn fuel, they do not produce greenhouse gas emissions.

3. Produces Radioactive Waste. Although nuclear energy production does not create any emissions, it does produce radioactive waste that must be securely stored so it doesn't pollute the environment. ... Storage of radioactive waste is a major challenge facing nuclear power plants.

effects: hair loss, skin burns, nausea, gastrointestinal distress, or death (Acute Radiation Syndrome). Long-term health risks include an increased cancer risk. Such risks depend upon the function of the specific radioisotope; and the route, magnitude, and duration of exposure.

Disadvantages of Nuclear Power The further implementations of nuclear power are limited because although nuclear energy does not produce CO2 the way fossil fuels do, there is still a toxic byproduct produced from uranium-fueled nuclear cycles: radioactive fission waste.

Plutonium, both that routinely made in power reactors and that from dismantled nuclear weapons, is a valuable energy source when integrated into the nuclear fuel cycle. In a conventional nuclear reactor, one kilogram of Pu-239 can produce sufficient heat to generate nearly 8 million kilowatt-hours of electricity.
