Abstract
A high pressure first stage turbine and seal assembly are described. In one embodiment, a high pressure turbine section is provided. The turbine section includes at least one stage, at least one rotor and a bucket assembly. The bucket assembly includes a bucket and an attachment fixture. The stage has a high root reaction during operation. An intermediate space is between the bucket assembly and a stationary component of the turbine section. A seal is provided between the stationary member and the rotor to facilitate preventing leakage from the intermediate space toward an end of the stage. Steam balance holes are provided in the rotor or the bucket to facilitate feeding steam towards an end of the turbine stage.
