A cooling fluid reuse system for a turbine engine for capturing spent cooling fluids from row one turbine vanes and directing those fluids into a mixing chamber to be mixed with liner cooling fluids and used in a combustor. The cooling fluid reuse system may be formed from a fluid channel extending from the a cooling fluid collection channel in the first row of turbine vanes, through a rotor cooling fluid collection chamber in the rotor assembly, through a cooling fluid manifold, and into the at least one mixing chamber.
