Claims

[Scope of utility model registration request]

In a double-flow steam turbine, through holes are provided in the first stage disk section with different radial heights on both sides of the disk, allowing low-temperature steam at the first stage nozzle port to flow around the rotor by pump action. A steam turbine characterized by:
