Abstract
According to an embodiment, at least one first outer ring has an annular outer ring cavity to which external cooling steam is supplied. A radial direction cooling hole connecting with the outer ring cavity is formed in the stator blades connected to the first outer ring. An annular inner ring cavity connecting with the radial direction cooling hole is formed in a first inner ring constituting one diaphragm together with the first outer ring. Cooling steam blowing holes connecting an annular wheel space and the inner ring cavity are formed. The annular wheel space is formed between the first inner ring and a rotor wheel adjacent to the first inner ring.
