高温ガス炉の保全技術の開発
概要
Japan Atomic Energy Agency has constructed the HTTR (High Temperature engineering Test Reactor), which is the Japa n's first High Temperature Gas-cooled Reactor (HTGR). The HTTR achieved the full power of 30MW and reactor outlet coolant temperature of 950°C on April 19, 2004. Based on the HTTR maintenance experiences, the preservation techno logy for HTGR are developed. This paper describes its preservation philosophy and typical developed technologies.
