Renaissance Fusion
Renaissance Fusion is a Stellarator fusion reactor company based in Grenoble, France.
Why wide HTS?
“To produce stellarator magnets, competitors wind narrow tapes (4-12 mm in width) on 3D structures. The complexity lies in fabricating the 3D structures and installing the tapes in 3D, with millimetric precision.”
View in the company profileAre there other benefits in wide HTS, besides your specific approach to fusion, and besides the possible indirect speed-up in producing narrow HTS?
“There is a wide range of applications for wide HTS, ranging from the simplification of HTS-based electric motors and generators especially for off-shore wind turbines, high-field gyrotron and MRI magnets, fault current limiters, undulators for synchrotrons and magnets for particle accelerators for physics research, material testing and cancer therapy.”
View in the company profileWhy do you need superconductors –or, specifically, HTS- for magnetic fusion?
“Superconductors are required to carry high electrical currents and thus generate the strong magnetic fields needed for magnetic fusion. Regular conductors like copper are not suitable for the job due to Ohmic losses caused by the Joule effect.”
View in the company profileWhat are the power requirements to refrigerate the HTS coils?
“For our 1 GWe stellarator fusion power plants, the power requirements for cryogenics are currently estimated to be less than 28 MW. Further work is underway to refine the calculations and cryogenic system design.”
View in the company profileWhere do you buy your HTS tapes?
“Meter-wide tapes are not available today. We are building the film-deposition machines that will demonstrate this technology and manufacture meter-wide HTS tapes in-house.”
