Very High Temperature Helium Experimental Loop (HELP)

Korea Atomic Energy Research Institute (KAERI) has developed the gas loops to develop and verify the key components of the nuclear hydrogen production system. At the present, KAERI is operating a small scale gas loop for feasibility tests of process heat exchanger and has constructed a very high temperature Helium Experimental LooP (HELP) for verification tests of scale-down prototypes for high temperature key components in Very High Temperature gas-cooled Reactor (VHTR). Figure 1 presents the HELP assembled with the key components. Design and operation experiences with a small-scale gas loop provide the basic information for design and construction of HELP. This paper introduces the design and specifications of HELP
