Milestone

4.8 km of cryolines pass leak test

Originating in the cryoplant, kilometres of sophisticated cryolines deliver cooling fluids to some essential elements of the ITER machine—the superconducting magnets, the cryopumps and the different parts of the thermal shield.

Close to five kilometres of cryolines and ''warm lines'' run through the ITER cryoplant. After more than a full year of work, an important milestone was passed last week as the entire network was successfully leak-tested. (Click to view larger version...)
Close to five kilometres of cryolines and ''warm lines'' run through the ITER cryoplant. After more than a full year of work, an important milestone was passed last week as the entire network was successfully leak-tested.
The cryoline network is built out of individual spools that measure up to 10 metres in length and range from 25 to 1000 millimetres in diameter. A section of cryoline can host up to six or seven "process pipes," each devoted to a specific fluid, flow direction or function. The Indian Domestic Agency, responsible for 100 percent of cryoline procurement, is working with two companies—France's Air Liquide and India's INOXCVA. The Indian firm is providing the totality of the piping inside the cryoplant.

One of the first and most obvious requirements for the cryoline network is to be perfectly leak-tight. After more than a full year of work, an important milestone was passed last week as all 4.8 kilometres of cryolines and "warm lines" inside the cryoplant were successfully leak-tested by the INOXCVA team operating under the responsibility of ITER India.

Looking for potential microfissures, a member of the INOXCVA team checks one of the 1,000 welds of the cryoline network inside the cryoplant. (Click to view larger version...)
Looking for potential microfissures, a member of the INOXCVA team checks one of the 1,000 welds of the cryoline network inside the cryoplant.
The network inside the cryoplant comprises close to 1,000 spools connected by an equal number of welds. About half the welds were randomly helium-tested prior to the final pressure test at 30 bars, which demonstrated the leak-tightness of the entire network.
