【考案の詳細な説明】
この考案は、金属に対する透過係数が大きく、
かつ有毒な三重水素（トリチウム）を反応除去す

反応容器に関するものである。[Detailed explanation of the invention] This invention has a large permeability coefficient for metals,
The present invention also relates to a tritium reaction vessel that can be safely handled in the reaction and removal of toxic tritium.

チウムを取扱う容器に使用する金属材料として、
当然のことながらトリチウムの透過係数の小さい
材料を選択しなければならない。 As is well known, tritium is known to have a high permeability coefficient to metals. Therefore, as a metal material used for containers that handle tritium,
Naturally, a material with a small tritium permeability coefficient must be selected.

欠点がある。しかも、周知のように、金属のガス
透過係数は、温度およびガス圧の上昇とともに増
加するものである。 By the way, tungsten steel and the like can be mentioned as a metal material having a small permeability coefficient for tritium. However, tungsten steel is expensive, and using this tungsten steel as a material poses a problem in that the reaction vessel becomes expensive. In addition, stainless steel is a metal that has a relatively small permeability coefficient for tritium and is relatively inexpensive, but stainless steel does not have sufficient sealing properties for tritium, and tritium is a radioactive substance that is dangerous if released into the atmosphere. It is not recommended as a material for containers in which it is handled. In particular, when tritium is removed by reaction, the temperature is high, further increasing the danger. On the other hand, aluminum can be cited as a metal that is relatively inexpensive and has a small tritium permeability coefficient, but this aluminum has the disadvantage of being inferior in heat resistance and pressure resistance. Furthermore, as is well known, the gas permeability coefficient of metals increases with increasing temperature and gas pressure.

ある。 For this reason, in reaction vessels that handle tritium, which has high gas permeability and is harmful, there is a contradictory relationship between improving gas sealing and reducing manufacturing costs, and it is important to satisfy both characteristics at the same time. Currently, research is being carried out with the aim of

ことなく両立させたものである。 This idea was made in view of the above circumstances,
The purpose is to provide a tritium reaction vessel that exhibits sufficient gas-tightness even under high temperature and high pressure conditions and can be manufactured at low cost. Furthermore, a heat insulating layer is formed between each cylinder to prevent heat from the inner cylinder from being transferred to the outer cylinder, achieving both improved gas sealing and improved heat and pressure resistance without increasing costs. It is something that

Twist and form. For example, when using a product under high temperatures that involve reactions, first consider heat resistance, and when using under high pressure, first consider high pressure resistance; both characteristics are required. In some cases, a material with high heat resistance and pressure resistance, such as stainless steel, is used to form the inner cylinder 1.

Furthermore, projecting pipes 3a and 3b are integrally connected to the side portions of the outer cylinder main body 3. These projecting pipes 3a and 3b are connected to a vacuum pump (not shown), and the inner cylinder 1 and the outer cylinder 2 are connected to each other by this vacuum pump.
The space between them is evacuated to form a vacuum insulation layer 7. In the above configuration, the inlet connecting pipe 1b and the inlet pipe 6a constitute a gas inlet 8a, and the outlet connecting pipe 1c and the outlet pipe 6b constitute a gas outlet 8b.
