The tritium systems test assembly at Los Alamos National Laboratory

John R. Bartlit1990年Fusion Engineering and DesignIF 1.7出版社

AbstractThe Tritium Systems Test Assembly (TSTA) at Los Alamos National Laboratory is a facility for the integrated testing, in full scale, of the processes and safety systems required for the reprocessing and recycling of plasma exhaust gas from a tokamak reactor. The facility can reprocess and reuse tritium at the rate of 1000 g per day, with a tritium inventory of 130 g. TSTA has been operated since 1984 with increasing amounts of tritium and an increasing degree of system integration without significant releases to the environment or doses to workers. Full loop integration was achieved in 1988. Since 1987, the TSTA has been jointly funded and jointly operated by the U.S. Department of Energy and the Japan Atomic Energy Research Institute. Objectives include: the demonstration of long-term reliability and safety, the qualification of equipment for tritium service, and the verification of a facility that can be copied for future fusion machines, such as the International Tokamak Experimental Reactor (ITER). Future plans include the installation and integrated testing of a new impurity removal system of Japanese design, testing the effect on the plasma exhaust gas reprocessing systems of off-normal conditions in the torus, and the development and testing of technology for processing tritium contained in a breeding blanket product stream.

ロスアラモス国立研究所のトリチウムシステム試験装置(TSTA)は、トカマク型原子炉からのプラズマ排気ガスの再処理と再利用に必要なプロセスと安全システムの実規模での統合試験を行うための施設である。この施設は、トリチウムインベントリ130 gで、1日あたり1000 gのトリチウムを再処理・再利用することができる。TSTAは1984年以来、トリチウム量の増加とシステム統合度の向上とともに運転されており、環境への顕著な放出や作業者への被曝線量はなかった。1988年に全ループ統合が達成された。1987年以来、TSTAは米国エネルギー省と日本原子力研究所によって共同出資・共同運営されている。目的には、長期信頼性と安全性の実証、トリチウムサービス用機器の認定、そして国際トカマク実験炉(ITER)などの将来の核融合装置に転用可能な施設の検証が含まれる。将来計画には、日本設計の新しい不純物除去システムの設置と統合試験、トーラス内の異常時条件がプラズマ排気ガス再処理システムに及ぼす影響の試験、そして増殖ブランケット生成物流に含まれるトリチウムを処理する技術の開発と試験が含まれる。
