本研究では、HTTRにガスタービンと水素製造施設を接続したHTTR-GT/H$$_{2}$$プラントの性能評価を行った。起動停止運転及び負荷追従運転について検討するとともに、発電機負荷喪失時や水素製造施設異常時におけるプラント動特性評価を行い、HTTR-GT/H$$_{2}$$プラントにより、実用高温ガス炉の運転制御技術の確証試験が実施できることを明らかにした。

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 procedure unique to HTGR direct-cycle gas turbine cogeneration.
