Mastering nuclear fusion offers the potential of responding to one of the major challenges of the 21st century in a context of increasing worldwide energy requirements and the preservation of natural resources. In particular, it allows the production of electrical energy.

The Korea Basic Science Institute (KBSI) is planning the creation of an experimental reactor designed to improve knowledge and mastery of thermonuclear fusion reactions through the KSTAR project (Korea Superconducting Tokamak Advanced Research).

This project is based around an ultra-sophisticated physics-based instrument known as the Tokamak.

In order to obtain the very powerful electromagnetic fields necessary for the confinement of this physical reaction, superconducting magnets must be used, which only function at extremely low temperatures. Helium, the lowest temperature liquefied gas on earth, will be used to carry out cooling of the Tokamak.

In practical terms, by the end of 2007, Air Liquide will implement a high-technology system that consists of a helium refrigerator ensuring the installation maintains a temperature of –269°C, in addition to the helium distribution system and all auxiliary equipment (compressor, filtering apparatus and cryogenic lines).

Air Liquide, a partner in the international scientific community, has developed leading expert knowledge at the forefront of the extreme gases field, as well as in specific technologies allowing sophisticated cryogenics systems to be used by universities and research centres.
