<p>A cooling circuit serves to provide cooling air in a rotor having a compressor rotor (12) and a turbine rotor (14). The cooling circuit includes a first cooling path (18) through the compressor rotor in series with a second cooling path (24) through the turbine rotor such that one amount of cooling air is used for cooling both the compressor rotor and the turbine rotor. The construction enables a reduction in cooling air requirements, thereby increasing power plant efficiency.</p>
