A kind of column stable sea nuclear power platform

The present invention relates to a kind of column stable sea nuclear power platform, nuclear power mesa base is provided with annular buoyancy tank, and annular buoyancy tank bottom can be fixed on shallow sea water seabed by suction pile foundation, and the horizontal brace in cross structure is provided with annular buoyancy tank hollow position；A column is respectively arranged with annular four corner positions in buoyancy tank top, column lateral surface is provided with catenary suspension type continuous vulcanization or tension type mooring system and positioned for deep water sea area；Annular buoyancy tank top is connected by column with platform deck bottom, and the axis of column overlaps with the axis of suction pile foundation；The nuclear island cabin of cylinder is provided between the horizontal brace middle of annular buoyancy tank and platform deck; nuclear island cabin upper end penetrates platform deck; and nuclear island cabin hatch board and preventing collision protection structure are provided with platform deck, in nuclear power platform, rear sea level is higher than submergence height needed for nuclear island cabin in place.Security of the present invention is good, simple in construction, installs simple, low engineering cost in place, can be shallow water and the exploitation of deep water sea area offshore oil and gas field, island and on the bank user provides stability, reliably, the energy that cleans.
