Description

Technical Field

[0001] The invention relates to the field of nuclear power plant detection, in particular to a hanging basket lifting mechanism. Background Art

[0002] With the development of the global economy and the growth of population, the demand for energy continues to increase. At the same time, people's awareness of environmental protection is also increasing. Traditional fossil energy such as coal, oil and natural gas will produce a large amount of greenhouse gases and pollutants during use, which has a serious impact on the environment. Nuclear power plants, as a clean and efficient energy source, can reduce environmental pollution while meeting energy needs. Nuclear power plants use the heat generated by nuclear fission or nuclear fusion reactions to heat water into steam and drive steam turbines to generate electricity. Nuclear fission refers to the splitting of heavy atomic nuclei (such as uranium-235, plutonium-239, etc.) into two lighter atomic nuclei under the bombardment of neutrons, while releasing a large amount of energy and neutrons. Nuclear fusion refers to the combination of light atomic nuclei (such as hydrogen isotopes deuterium and tritium) into heavier atomic nuclei under extremely high temperature and pressure, releasing huge energy.
