Выбрать правильный вариант Protection Against Environmental Pollution
Any operating nuclear power plant releases fission products into the environment, which causes environmental pollution.
To prevent the harmful effects of nuclear power release , the nuclear power plants are supplied with protective installations that serve as barriers to the pollution.
First, the nuclear fuel and the fission products are confined within sealed tubes made of stainless steel or zirconium. Then the assembly of tubes is placed in a steel reactor vessel. And finally the steel reactor vessel is placed in a large steel and concrete housing.
As to the hot radioactive waste products they are disposed in heavily shielded cylinders. The cylinders are buried 305 to 610 metres underground.
