HTTR-GT/H2 test plant – System performance evaluation for HTTR gas turbine cogeneration plant

Abstract This paper presents the system performance evaluation for HTTR gas turbine cogeneration test plant (HTTR-GT/H 2 plant) so as to confirm that the design meets the requirements with respect to the demonstration test objective. Start-up and shut down operation sequences as well as operability of load following operation were investigated. In addition, system dynamic and control analyses for the test plant in the events of loss of generator load and upset of H 2 plant were performed. The simulation results presented in the paper show that the test plant is suitable for the test bed to validate control schemes against postulated transients in the commercial Gas Turbine High Temperature Reactor Cogeneration (GTHTR300C). The results also lead us to the conclusion that HTTR-GT/H 2 plant can be used to test operational procedures unique to HTGR direct-cycle gas turbine cogeneration.
