Offshore nuclear power platform for shallow ice sea regions

The invention relates to an offshore nuclear power platform for shallow ice sea regions. The offshore nuclear power platform is provided with more than three suction pile foundations, wherein one end of each suction pile foundation is connected with a seabed; the other end of each suction pile foundation is connected with the bottom of a cylindrical buoyancy tank, and each suction pile foundation can be separated from the cylindrical buoyancy tank; the top periphery of the cylindrical buoyancy tank is connected with the bottom of a platform deck through more than three stand columns; a cylindrical nuclear island chamber is arranged between the middle of the top of the cylindrical buoyancy tank and the platform deck; the upper end of the cylindrical nuclear island chamber is communicated with the platform deck, and a nuclear island chamber cap and an anti-collision protection structure are arranged on the platform deck; after the nuclear power platform is positioned, the sea level needs to be higher than the height of sea submerging the nuclear island chamber. The offshore nuclear power platform disclosed by the invention is high in safety and simple in structure; the platform construction has no special requirements; for transit, dry transport of barges can be adopted, and wet transport in the state that the platform floats can also be adopted; the mounting and positioning procedures are simple, and the construction cost is low; the offshore nuclear power platform can provide stable, reliable and clean energy sources for the development of offshore oil and gas fields in the shallow ice sea regions, and users on islands and seashores.
