Tungsten Alloy Nuclear Island Radiation Shielding

Tungsten alloy nuclear island radiation shielding is widely used in nuclear power plants to shield radiation generated by the nuclear island. A nuclear power plant is a thermal power station in which the heat source is a nuclear reactor. Nuclear reactor, also known as nuclear island, is made up of nuclear steam supply system, containment spray system and auxiliary system (including equipment cooling water system, the reactor chamber and spent fuel cooling system, auxiliary feedwater system, ventilation and air conditioning systems, compressed air system and radioactive waste treatment systems). As is typical in all conventional thermal power plants the heat is used to generate steam which drives a steam turbine connected to an electric generator which produces electricity.

When fission occurs,the nucleuses of the uranium, plutonium and other nuclear fuel nuclear split into two or more lower-mass atoms, releasing huge amounts of energy. The most common uranium fission is releasing two to four neutrons by bombarding uranium-235 with thermal neutrons, the neutrons then sequentially bombard other uranium 235 atoms, thereby forming a chain reaction. While the process of nuclear fission will produce nuclear radiation (such as neutron, gamma ray and other), which takes a toll on health by damaging normal mechanism in human body to cause cells to become cancerous，and severely impacting human important biochemical structure and function by breaking chemical bonds between molecules and atoms in the body. Nuclear radiation can also lead to fatigue, dizziness, insomnia, skin redness, ulceration, bleeding, hair loss, leukemia, vomiting, diarrhea and other symptoms, and increase disease incidence of cancer, distortion, hereditary disease. Therefore, the use of tungsten alloy nuclear island radiation shielding is a good choice to shield and absorb nuclear radiation produced by nuclear island, to avoid a significant impact arising from a radiation leak.

Since nuclear island is one of the main components of a nuclear power plant, tungsten alloy nuclear island radiation shielding is widely used in nuclear power plants. Tungsten alloy nuclear island radiation shielding has high density and excellent radiation shielding ability, so that can effectively absorb and shield radiation to reduce radiation hazards. And compared with conventional shielding materials (such as lead), tungsten alloy nuclear island radiation shielding is nontoxic and environmentally friendly material which does not release substances harmful to human health or the environment.
