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の黒鉛減速ヘリウムガス冷却型原子炉で、我が国初の高温ガス炉である。平成25年度は、平成25年12月に施行された試験研究用等原子炉施設の新規制基準の適合のための原子炉設置変更許可申請書の作成等を行い、平成23年東北地方太平洋沖地震以来運転停止しているHTTRの再稼働に向けての活動を実施した。本報告書は、平成25年度(2013年)のHTTRの運転と保守及び各種技術開発の状況等について紹介する。

The High Temperature Engineering Test Reactor (HTTR) constructed 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 which is a graphite-moderated and helium gas-cooled reactor with 30MW of thermal power. In fiscal year 2013, we started to prepare the reactor installation application for the HTTR to prove conformity with the new research reactor's safety regulatory requirements taken effect from December 2013. We had been making effort to run the HTTR which was stopped since the 2011 in which the Pacific coast of Tohoku Earthquake (2011.3.11) occurred. This report summarizes activities and results of HTTR operation, maintenance, and several R&Ds, which were carried out in the fiscal year 2013.
