Beschreibung
Zusammenfassung:	Various embodiments include a rotor key member, along with a related assembly and steam turbine. Particular embodiments include a rotor key member for circumferentially retaining a circumferential seal in a steam turbine rotor body, the rotor key member having: a main body sized to contact an axial face of the circumferential seal; and a locking member extending from the main body in a direction axially toward the circumferential seal, the locking member having at least one circumferential edge sized to substantially complement a corresponding slot in the circumferential seal to restrict movement of the circumferential seal relative to the steam turbine rotor body.
