核融合反応炉は、軽水炉等の原子ｈエネルギーに次ぎ次
世代のエネルギー創出の手段として鋭意研究が行なわれ
ている。Nuclear fusion reactors are being intensively researched as a means of creating next-generation energy following atomic energy such as light water reactors.
この′核融合反応（２Ｈ＋” Ｈ＝４ ）１ｅ ＋ｎ等
の核融合反応で地上に太陽の状態を創造）を実現するに
は、まず臨界条件（温度約１億度Ｃ、プラズマ密度約３
０億個／α３、エネルギー閉じ込め時間約１秒）を作り
出さなければならない。世界は今、この条件の実現に向
って衆知を傾注している。In order to realize this 'nuclear fusion reaction (2H+'' H=4)1e +n, etc., which creates the state of the sun on the ground), the critical conditions (temperature of about 100 million degrees Celsius, plasma density of about 3
0 billion pieces/α3, energy confinement time approximately 1 second). The world is currently concentrating its collective wisdom on realizing this condition.
このような核融合炉の一つに、トカマク方式の炉がある
が、これは巨大なドーナツ状をしており真空容器の内部
に発生させる超高温プラズマを、周囲に設けられた巨大
な磁石（ホロイダルマグネット、トロイダルマグネット
）により、その磁力の力で閉じ込め宙に浮かして保持す
るようにしたものである。One such nuclear fusion reactor is the tokamak type reactor, which is shaped like a giant donut and uses a huge magnet ( Holoidal magnet, toroidal magnet) is used to trap and hold it in the air by its magnetic force.
ここに使用される真空容器には、従来インコネル（Ｎｉ

れている。The vacuum container used here is conventionally made of Inconel (Ni).
-Cr-Fe alloy: trademark of lNC0 company (same as below),
Stainless steel (SUS 304, 316) etc. are used.
しかしながら、これらは高速中性子の照射により長寿命

らの成分が放射化してγ線が発生する。However, these elements (e.g., Ni, Go,
, Mn, Fe). Therefore, when Inconel or stainless steel is used for a vacuum container, D-T ('2
H-38) These components are activated by neutrons generated by nuclear fusion repulsion, and gamma rays are generated.
結果として、その装置への研究者や作業者の接近が困難
となる。ロボットにより遠隔操作する方法もあるが、多
額の開発費と長期の研究期間を要する。そこで低放射化
材料であるＡ（合金材が注目され、一部溶接性のよイＪ
ｒｓ５０５２ｕ （Ａｆ−２，２〜２，８ｖｔ％ＭＱ
−０，１５〜０．３５ｗｔ％ｃｒ合金）が使用された
実績がある。As a result, it becomes difficult for researchers and workers to access the device. There is also a method of remote control using a robot, but this requires a large amount of development cost and a long research period. Therefore, A (alloy material), which is a low activation material, has attracted attention, and some J
rs5052u (Af-2,2~2,8vt%MQ
-0.15 to 0.35 wt% Cr alloy) has been used.
しかし従来使用されたＡ（合金材にしても、多くの改善
を必要とする。即ち微量放射化成分の除去、材料強度の
上昇、溶接性の改善、電気抵抗特性等である。However, the conventionally used A (alloy material) requires many improvements, such as removal of trace amounts of activated components, increase in material strength, improvement in weldability, and electrical resistance properties.
真空容器の設計上、Ａぶ合金材に要求される特性として
は、次のとおりである。In designing a vacuum vessel, the following properties are required of the aluminum alloy material.
（１）大型構造物であるため、材料の強度が所定以上あ
ること。(1) Since it is a large structure, the strength of the material must exceed a specified level.
（例、引張強さ２８８ｇ／１ｕｒｎ２以上、耐力１２Ｋ
ｇ／′＃ＩＩ＋２以上を目標とする。）
（２）厚板（板厚３０〜５Ｏ，）を曲げ加工して、構造
物とするため、材料の伸びが所定以上であること。(Example, tensile strength 288g/1urn2 or more, yield strength 12K
Aim for g/'#II+2 or higher. ) (2) Since a thick plate (plate thickness 30 to 50) is bent to form a structure, the elongation of the material must be at least a predetermined value.
（例、１３％以上を目標とづる。） （３）材料の電気抵抗が大きいこと。(For example, set a goal of 13% or more.) (3) The electrical resistance of the material is high.
（例、５μΩ・ｃｍ以上を目標とする。）（４）各板を
溶接により接合しで構造物とするため、溶接性が良好な
こと。(For example, aim for 5 μΩ・cm or more.) (4) Since each plate is joined by welding to form a structure, weldability must be good.
等である。etc.
尚真空容器用材料の電気抵抗を人さくする主な理由は、
真空容器の内部に、ブラズン電流を外部（ホロイダルマ
グネット）からの誘導で励起するため真空容器の一周抵
抗値を所定値（例えば０．１ｍΩ）以上とする必要があ
るためである。The main reason for reducing the electrical resistance of vacuum container materials is
This is because the one-round resistance value of the vacuum container needs to be equal to or higher than a predetermined value (for example, 0.1 mΩ) in order to excite the blast current inside the vacuum container by induction from the outside (holoidal magnet).
