What is High Temperature Gas-cooled Reactor (HTGR) ?
Superior inherent safety
Specification of High Temperature engineering Test Reactor （HTTR）
Safety demonstration test with HTTR
- Reactor power 30%（9MW）
- Tripping all gas circulators to reduce primary coolant flow rate to zero. → No core cooling！
- No reactor scram operation of reactor （No control rod insertion）.→ No core reactivity control！
Technology of water splitting hydrogen production –Thermochemical IS process-
Reaction scheme and features
■Thermal water decomposition：
- Heat over 4000ºC is required.
- Chemical reactions of iodine (I) and sulfur (S) enable water decomposition at about 900ºC.
→ No release of harmful chemicals
・HTGR supplies heat energy driving the process.
→ No emission of CO2
