2221 HTTR 水素製造システムのプラント動特性に関する検討

抄録

Development of control technology for the HTTR hydrogen production system is very significant issue. JAERI proposed the thermal turbulence mitigation system using the steam generator (SG) and performed the plant dynamics analysis to verify the availability of this system. The result shows that the temperature fluctuation of SG outlet is very mild in start up operation. In case of the reformer operation suspension, the SG can cool down the hot helium gas instead of the reformer and mitigate the thermal turbulence, so that the reactor scram can be prevented.
