Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a cooling flow to cooling passages in turbine buckets and to bucket platforms.SOLUTION: There is provided a casted turbine bucket having at least one machined plenum including a plenum chamber and at least one plenum passage connected to a plenum inlet located at a root portion of turbine bucket. There is also provided a method of feeding a cooling flow to the turbine bucket using the machined plenum that receives the cooling flow from the root portion of the turbine bucket.SELECTED DRAWING: Figure 3 【課題】タービンバケットにおける冷却通路及びバケットプラットフォームに冷却流を提供すること。【解決手段】プレナムチャンバとタービンバケットの根元部分にあるプレナム入口に接続された少なくとも１つのプレナム通路とを含む少なくとも１つの機械加工されたプレナムを有する鋳造タービンバケット、並びに、タービンバケットの根元部分から冷却流を受ける機械加工されたプレナムを用いてタービンバケットに冷却流を送給する方法が提供される。【選択図】図３
