Claim 16:
17. A turbine system component for a turbine system, the turbine system component comprising:
a body having an exterior surface;
a cooling passage defined in the body and extending to an exterior surface of the body, the cooling passage having a first cross-sectional area, the cooling passage including:
a first plurality of cooling passages defined in the body, each of the first plurality of cooling passages having the first cross-sectional area; and
a second plurality of cooling passages defined in the body, each of the second plurality of cooling passages having the first cross-sectional area in the body and exiting the exterior surface of the body at a second exit opening defined in the body having the first cross-sectional area; and

a hollow member coupled in the cooling passage and defining a first exit opening at the exterior surface of the body, the first exit opening in the hollow member having a second cross-sectional area that is less than the first cross-sectional area,
wherein the hollow member is made of a material having a melt temperature higher than an operating temperature of the turbine system, and
wherein the hollow member has an external cross-section having a shape corresponding to a shape of an internal cross-section of at least a corresponding portion of the cooling passage, wherein the hollow member has an internal cross-section having a shape that differs from the shape of the external cross-section of the hollow member, and wherein the shape of the internal cross-section of the hollow member is continuous over an entire length of the hollow member, and further wherein a respective hollow member defines the first exit opening at the exterior surface of the body having the second cross-sectional area for each of the first plurality of cooling passages.
