日本原子力研究開発機構大洗研究開発センターのHTTR(高温工学試験研究炉)は、熱出力30MW,黒鉛減速ヘリウムガス冷却の我が国初の高温ガス炉である。HTTRは平成16年4月に世界で初めて原子炉出口冷却材温度950Cを達成し、6月には原子炉出口冷却材温度950Cにおける使用前検査合格証を取得した。本書は、平成16年度のHTTRの運転と保守及び技術開発の状況等について紹介する。
The High Temperature Engineering Test Reactor (HTTR) at the Oarai Research and Development Center of the Japan Atomic Energy Agency (JAEA) is the first high-temperature gas-cooled reactor (HTGR) in Japan with thermal power of 30MW, which is a graphite-moderated and helium gas-cooled reactor. In April 2004, the HTTR achieved the maximum reactor outlet temperature of 950 degree for the first time in the world. In June 2004, JAEA obtained commissioning license from the MEXT for the operation at 950 degree. This report summarizes activities and results on HTTR operation and maintenance as well as several R&Ds, which were carried out in the fiscal year of 2004.
