A method is provided for sealing a gap between a bucket dovetail and a rotor wheel slot. The method includes providing a bucket tab (502) associated with a bucket dovetail, wherein the bucket tab (502) is configured to accept a seal tab (506); configuring the bucket tab (502) and the seal tab (506) to engage at least one dimension upon insertion of the seal tab (506) into the bucket tab (502); and sealing a gap between the bucket dovetail and a rotor wheel slot (202) with the seal tab (506); wherein at least a portion of the seal tab (506) changes as a function of temperature for further sealing gap between the bucket dovetail and the rotor wheel slot. |
