PROBLEM TO BE SOLVED: To provide a seal activated by pressure differential formed over a rotary component and a stationary component of a steam turbine. SOLUTION: A pressure activated flow path seal for a steam turbine (100) is disclosed. In one embodiment, a gap closure component is located about the rotary component (105) and the stationary component (110) of the steam turbine (100). A pressure differential activates the gap closure component to seal or reduce the radial clearance of a steam leakage path between the rotary component (105) and the stationary component (110).
