Nuclear energy refers to the process electricity generation through nuclear energy that is released by nuclear reactors. The term includes nuclear decay, nuclear fusion and nuclear fission. Nuclear fission of element in the periodic table’s antacid series generates the highest level of nuclear energy that directly serves humankind, with processes of nuclear decay, primarily in the form of radioisotope thermoelectric generators and geothermal energy. Excluding the naval nuclear fission reactors’, in 2012, nuclear (fission) power stations, provided 13 percent of world electricity.
According to the 2013 IAEA report, there are four hundred and thirty-seven active nuclear power reactors stations in thirty-one countries though electricity is not generated from all the reactors. Also, there is an estimate of one hundred and forty naval vessels that makes use of nuclear propulsion for their operations, powered by some one hundred and eighty reactors. According to an ongoing debate, proponents such as the IAEA, the environmentalists for nuclear energy and world nuclear association recommend that nuclear power is a sustainable and safe energy source that prevents environmental degradation through carbon emissions.
Uses of nuclear power
Though nuclear is broadly used for the generation of electricity, this is not the only use it can be assigned. The type of energy presents itself in many other aspects of science and our daily lives. It is possible to use nuclear technology for other fields’ applications by working with different isotopes of a similar element.
Firstly, nuclear power technology is used in military, nuclear weapons. Nuclear technology is vastly used to develop nuclear weapons. The use of nuclear technology in nuclear weapons is of two types depending on the role it plays. The types are; those that use nuclear energy for propulsion like submarines and aircraft carriers and those that use nuclear energy for explosion like atomic bomb
Secondly, nuclear power technology is used in medicine. In every three patients who visit the hospital in an industrialised nation, one enjoys the benefits of any nuclear medicine procedure. Radiation therapy and radiopharmaceuticals techniques for malignant tumours’ treatment, radiation biology to sterilize medical procedures and teletherapy for the treatment of cancer are used.
Disadvantages of nuclear power
There is a problem of radioactive waste disposal. The waste generated by nuclear reactors requires to be disposed of at a safe place due to their extremely hazardous nature and can cause radiation leakage if improperly stored. The kind of waste produced by radioactive waste emits radiation from tens to hundreds of years.
