Innovative, high-quality solutions for X-ray imaging systems
For years, AVELION has been working closely with our customers and collaborators to fully understand their specific needs and requirements, delivering high-quality, innovative, and tailor-made solutions for X-ray imaging systems.
ITER Vacuum Vessel Weld Inspection Project
- ITER is a major international scientific project to build the world’s largest fusion energy experiment
- AVELION is developing a dedicated Linac solution for ITER to perform radiographic inspection of Tokamak sector welds, avoiding the use of radioactive sources that decay over time
- Faster inspections, safer operations and uncompromised image quality
AVELION is developing a dedicated Linac solution, replacing the radioactive sources use, to meet ITER requirements for radiographic inspection of the sector field joint welds on the ITER Tokamak.
Unlike conventional radioactive sources, which progressively lose activity and dose rate over time, the AVELION Linac delivers consistent, long-term inspection performance, ensuring reliable weld evaluation throughout its operational lifetime. Compared to traditional inspection technologies, the AVELION Linac solution offers clear and decisive advantages:
Ultra-short exposure time
A complete radiographic inspection can be performed in less than 10 minutes (Vs more than 4 hours for a 60 mm stainless Steel radiography).
Enhanced radiation safety
Radiation is generated only when the system is powered on, eliminating risks during transport, storage and handling.
Full dose traceability
An integrated dose monitoring system enables precise control and recording of delivered dose and exposure parameters.
Highly accurate dose placement
Source collimation combined with a motorized positioning system ensures the dose is delivered exactly where required.
Linac solution for the Jules Horowitz Reactor Project
- The Jules Horowitz Reactor (RJH) is a European research reactor under construction in France
- Modular high-performance X-ray solution delivered to CEA Cadarache (RJH) for non-destructive testing of irradiated and non-irradiated nuclear components
- Single 6 MeV LINAC shared across three stations delivers wide-range, high-resolution inspections with a mobile, self-shielded design suited for nuclear environments
The Jules Horowitz Reactor (RJH) is a research reactor led by the French Atomic Energy Commission (CEA) and currently under construction at Cadarache, France. Its main purpose is to test how nuclear materials and fuels behave under irradiation, supporting the safety and performance of current and future nuclear reactors. In addition, the RJH will produce radioisotopes for medical applications and for non-nuclear industrial uses.
AVELION delivered a modular high-performance X-ray imaging solution for the non-destructive examination of irradiated and non-irradiated experimental components at the Jules Horowitz Reactor (RJH), CEA Cadarache.
