Cryogenic safety valves to protect systems in ITER during quench.

Number: pap. n. 0094

Author(s) : BOERSCH M., DRACHE J., WEBER D.

Summary

ITER is an international project to build a fusion reactor and for scientific and technical study of fusion power generation. Helium cooled superconducting magnets provide important functional components of this system. In case of failure, for example by a magnet quench, large amounts of the refrigerant will be heated up leading to a rapid increase in pressure. To limit this pressure quench valves are used, which conduct the cryogenic helium into the collecting vessels. For this purpose specific safety valves are designed and manufactured. In addition to the international standards, these valves have specific requirements such as
compactness, radiation- or mechanical stability.
