Abstract
A seal assembly for use with a turbine having a rotor and at least one turbine blade facilitates the use of a wire seal with seal plate segments. The seal assembly includes a plurality of seal plate segments and a plurality of retainers disposed on a rotor flange on the rotor. A seal member is disposed between the retainers and the seal plate segments. The seal assembly includes at least one attachment member disposed through the rotor flange that limits radial displacement of the seal plate segments.
