Electrical control ensured in the world’s largest fusion reactor (ITER)

THE CHALLENGE: Ensure the safe operation of cryogenic lines transporting helium at -269 °C under extreme conditions of temperature, magnetic fields, and radiation.

The cryogenic lines at ITER carry supercritical helium at high temperatures, requiring components that can operate reliably under extreme conditions. Our Luxor enclosures provide exceptional sealing and resistance, ensuring the safe and continuous operation of the cryogenic system.

ADVANTAGES OF THE IMPLEMENTED SOLUTION

• High-strength material: The enclosures supplied by Delvalle are made of AISI 316L stainless steel, providing outstanding corrosion resistance—ideal for harsh environments like ITER.
• IP66 protection rating: Ensures total protection against dust and powerful water jets, crucial for maintaining the integrity of electrical connections in cryogenic zones.
• Designed for extreme temperatures: Capable of operating from -60 °C to +180 °C, guaranteeing continuous performance even under extreme cryogenic conditions.
• Standards compliance: International certifications such as UL NEMA 4X and RoHS reinforce customer confidence in safety, quality, and reliability.
• Tailor-made solution: With over 50 years of experience, we adapted our solution to the specific requirements of ITER’s cryogenic lines, ensuring a perfect fit for the environment.

RESULTS ACHIEVED

• Reliability in extreme conditions: Delvalle's junction boxes have proven optimal performance under the demanding conditions of the ITER project, safeguarding the integrity of the cryogenic system.
