An apparatus for routing fluid in a steam turbine is provided. The steam turbine includes a stage comprising a plurality of buckets secured to a rotor. The rotor is configured to rotate in response to a first volume of fluid flowing from an inlet passageway past the plurality of buckets. The apparatus includes a member having a fluid passageway extending therethrough. The fluid passageway includes a first end in fluid communication with a discharge side of the stage of the steam turbine. A second volume of fluid comprising a portion of the first volume of fluid is received into the fluid passageway at the discharge side of the stage and is discharged out of an outlet of the fluid passageway. The outlet is in fluid communication with a region between an upstream side of the stage and a sealing member disposed against the rotor. The region receives a third volume of leakage fluid from the upstream side of the stage. The second volume of fluid discharged out of the outlet both reduces the third volume of leakage fluid entering the region and increases the first volume of fluid flowing past the plurality of buckets to increase an amount of torque of the rotor.
