Out-of-Pile Test Program of HTTR Hydrogen Production System

Abstract

JAERI has been developing a hydrogen production system coupled with HTTR to demonstrate effectiveness of high-temperature nuclear heat utilization. Prior to construction of HTTR hydrogen production system, an out-of-pile test facility was fabricated to investigate transient behavior of the hydrogen production system and establish system controllability. The test facility is an approximately 1/30-scale model of the HTTR hydrogen production system and simulates key components downstream from an intermediate heat exchanger. An electric heater is used as heat source instead of a reactor. In the performance test of the test facility carried out from October, 2001 to February, 2002,the hydrogen production of 120m^3_N/h with hot helium gas was successfully achieved. This report describes the out-of test program and results of the performance test.
