Progress in developing a gas turbine system for a combined-cycle power plant is reported. Installation work has begun on the facilities services for the Hot Gas Path Development Test Stand (HGPDTS). Bids for composite nozzle fabrication are being reviewed. The Turbine Simulator combustor and check-out test section have been assembled and are ready for startup. Fabrication of other test sections and support equipment are in process. Bucket partitions and sidewall pressure taps are being fabricated preparatory to shock tunnel tests. The Pilot Gas Cleanup System (PGCUS) detail mechanical and electrical design has been completed, and subcontracts for building the system have been awarded. Cascade model fabrication and instrumentation details have been defined. A test plan to perform flow measurements on the cascade model has been assembled. Tests to determine the calibration of specimen convective heat loss and the water temperature rise were conducted in the motorized test rig. Results are reported. All instrumentation of the air turbine test specimens is complete. The Overall Plant Design Description cycle has been updated to reflect changes in gas turbine and steam cycle configurations. The overall plant coal pile-to-busbar efficiency has been calculated to be 40.9%. Preliminary design, including geometry definition and velocity distribution, for all turbine blade rows has been completed. Combustor cooling flow requirements have been defind and cooling grooves are being added to the liner panels to reduce in-plane stresses. The First Stage Nozzle cooling tube may increase in wall thickness thereby realizing a fabrication benefit. Analytical results have established that previously reported effective strains are higher than the true values. A heat transfer and thermal strain analysis of the Second Stage Nozzle (pitchline model) has been completed. The updated status of Materials Development efforts for the nozzles and buckets of all three turbine stages is included.
