ITERのような将来の核融合炉における室内のトリチウムの挙動を把握するために、トリチウム安全性試験装置(CATS)を設置し、さまざまな研究を実施した。おもに、室内へ漏洩したときの初期のトリチウムの挙動の把握及び解析コードの開発,トリチウムの室内漏洩時のトリチウムの閉じ込め機能の確認,漏洩したトリチウムのトリチウム除去設備による除去挙動の把握を目的とし、研究を実施し、その成果についてまとめた。

In order to accumulate the tritium behavior in the future fusion reactor included ITER, intentional tritium release experiments have been carried out using Caisson Assembly for Tritium Safety study (CATS) at Tritium Process Laboratory (TPL) in Japan Atomic Energy Agency (JAEA). Main objectives of CATS are (1) to demonstrate the initial tritium behavior in the room and to develop 3D simulation code of tritium behavior in the room. (2) to demonstrate the performance of integrated system for tritium confinement after intentional tritium release accident, (3) to accumulate the data for the detritiation behavior and the interaction between various materials and tritium (tritiated water) in the confinement. The study using CATS has been continued for about 10 yeas in TPL/JAEA.
