A technology development of a hydrogen production system by a nuclear heat is being performed as a heat application system of a high-temperature gas cooled reactor in the Japan Atomic Energy Research Institute. The objective of this study is to clarify heat transfer characteristics of the steam reformer inserted metallic wire with high porosity. An experiment has been performed using a double coaxial channel and single channel with metallic wire to obtain the heat transfer characteristics. From the results obtained in this experiment, it seems to be probable that an enhancement of heat transfer method using metallic wire inserts is further improved under the high temperature conditions in efficiency as compared with the conventional reformer.
