Disclosed herein is a rotor assembly for a steam turbine including a stacked rotor section having rotor plates. The rotor plates include a main body portion having a plate shape and a first axial face and a second axial face opposite to the first axial face. The rotor plates also include an airfoil base surface at an outer radial edge of the main body portion. The rotor plates further include buckets which extend radially outward from the airfoil base surface. And the rotor plates yet further include a seal disposed to prevent steam exposure to the first and second axial faces.

A cooling system for a turbine with a first section and a second section. The first section may include a first line for diverting a first flow with a first temperature from the first section, a second line for diverting a second flow with a second temperature less than the first temperature from the first section, and a merged line for directing a merged flow of the first flow and the second flow to the second section.

Disclosed herein is a rotor assembly for a steam turbine. The steam turbine includes a retention portion having a stacked rotor section. The steam turbine further includes a first shaft end disposed at a first end of the retention portion. The steam turbine yet further includes a second shaft end disposed at a second end of the retention portion that is opposite to the first end of the retention portion.

A method of fabricating a turbine rotor is provided. The method includes fabricating a plurality of substantially cylindrical disks. Fabricating each disk includes fabricating a substantially cylindrical body and extending a bore substantially concentrically through the body. The method also includes coupling at least two of the plurality of disks together to form a rotor having a bore extending axially therethrough.
