"textContent": "Embodiments of the invention relate generally to turbines and, more particularly, to steam turbines, single-shaft combined-cycle turbines, and turbine systems having novel startup cooling flow configurations. In one embodiment, the invention provides a single-shaft combined-cycle turbine (3000) comprising: a gas turbine (2100); a steam turbine (2200) including: a high-pressure section (2280); an intermediate-pressure section (2240); and a low-pressure section (2210) having a plurality of stages (2212A-H); a turbine shaft (2300) disposed within and between both the gas turbine (2100) and the steam turbine (2200); a first cooling steam flow inlet (2222) adjacent a first (2212C) of the plurality of stages (2212A-H) of the low-pressure section (2210); and a second cooling steam flow inlet (2224) adjacent a second (2212H) of the plurality of stages (2212A-H) of the low-pressure section (2210).",
