Operational aspects of tritium injection into the JET tokamak

R Felton, S Bickerton, L Horton, D Ciric, S Knipe, P Middleton, J Banks, P McCullen, I Carvalho, F Rimini2025年9月Plasma Physics and Controlled FusionIF 2.2出版社

The joint European torus (JET) was the only tokamak capable of deuterium–tritium (D–T) operations in the last 30 years. The first D–T operations were in the 1990s and again in 2004. In 2020/2021/2023, JET operated a much larger D–T and pure T campaigns aimed at sustained high fusion power, requiring a much higher tritium throughput. This paper presents operational aspects of the recent tritium injections into the JET tokamak. Tritium injection into the JET tokamak involves transfer of tritium between the Active Gas Handling System (AGHS) and the tritium gas injection modules (TIMs) and neutral beam injectors (NBIs), the control of TIMs, and NBI, gas inventory (pre-pulse estimate, post-pulse usage), gas limits (explosive, tritium) etc. Operations require close collaboration of staff in the JET Control Room,), AGHS, vacuum, and cryogenic groups.

共同欧州トーラス(JET)は、過去30年間において重水素–トリチウム(D–T)運転が可能な唯一のトカマクであった。最初のD–T運転は1990年代に行われ、2004年にも再び行われた。2020年/2021年/2023年には、JETは持続的な高核融合出力を目的とした、はるかに大規模なD–Tおよび純Tキャンペーンを運転し、はるかに高いトリチウム処理量が必要とされた。本論文は、JETトカマクへの最近のトリチウム注入に関する運転上の側面を提示する。JETトカマクへのトリチウム注入には、活性ガス処理システム(AGHS)とトリチウムガス注入モジュール(TIMs)および中性粒子ビーム入射装置(NBIs)との間のトリチウム移送、TIMsおよびNBIsの制御、ガスインベントリ(パルス前推定、パルス後使用量)、ガス制限(爆発性、トリチウム)などが含まれる。運転には、JET制御室、AGHS、真空、および極低温グループのスタッフの緊密な連携が必要である。
