Abstract

A helium engineering demonstration loop (HENDEL) was constructed and operated in JAERI in order to develop the high-temperature key components of an experimental very high temperature gas cooled reactor, like fuel stack, in-core reactor structure, hot gas duct, intermediate heat exchanger. Performance tests as well as demonstration of integrity are carried out with large-size or actual-size models of key components. The key components to be tested in HENDEL are: fuel stack and control rod. Core supporting structure, or bottom structure of rector core exposed to direct impingement of high temperature core outlet flow. Reactor internal components and structure. High temperature components in heat removal system (primary and secondary cooling systems).
