OUT-OF-PILE DEMONSTRATION TEST PROGRAM OF HTTR HYDROGEN PRODUCTION SYSTEM BY STEAM REFORMING OF NATURAL GAS

摘要

JAERI has been constructing a 30-MWt HTGR, named HTTR, to develop technology and to demonstrate effectiveness of high-temperature nuclear heat utilization. A hydrogen production system by natural gas steam reforming is to be the first heat utilization system of the HTTR. Prior to coupling of the steam reforming system with the HTTR, an out-of-pile test is planned to confirm safety, controllability and performance of the steam reforming system under simulated operational conditions. The out-of-pile system is an approximately 1/30 scale system of the HTTR steam reforming system and simulates key components downstream from an intermediate heat exchanger.This report describes the present status of the out-of-pile test system and demonstration test program at present status.
