JAERI has constructed a 30-MWt HTGR, named HTTR, of which first criticality was attained in 1998. A hydrogen production system by means of steam reforming of natural gas is planned as the first nuclear heat utilization system coupling with HTTR. A reformer is a key component to produce hydrogen by steam reforming. Heat consumption of the reformer significantly effects on the heat balance of hydrogen production system. This report describes the numerical analysis results for the reformer using mathematical model on heat and mass balance. It was investigated the effects of operating conditions, flow unbalance among catalyst tubes and choking in catalyst bed on hydrogen production rate and heat consumption of the reformer. And CO_2 reforming to reuse CO_2 as a raw material was also investigated focusing on hydrogen and CO production rates for methanol synthesis.
