In current, the nuclear energy is the Steam turbines need to be safer and more reliable when only energy source which can replace the traditional coal-fired used in nuclear power plants. In order to ensure long-term power plant in a wide range. reliability of the nuclear power equipment, the high safety With the restart of Chinese nuclear power market after the factor is usually adopted in the design of LP inner casing of accident at Fukushima Nuclear Power Plant, nuclear power steam turbines. It not only leads to larger self-weight of LP industry has been rapid development in China. the technology inner casings and fundamental load, but also causes higher of nuclear power continues to improve, and the evaporation manufacturing and transportation costs. In this paper, the stress amount of nuclear island and output power of the unit is and deformation behav
