French Nuclear Safety and Radiation Protection Authority Approves Exemption of ITER Vacuum Vessel from Fission Pressurized Equipment Regulation
The French Nuclear Safety and Radiation Protection Authority (ASNR) has formally issued a regulatory ruling, approving the application by the International Thermonuclear Experimental Reactor (ITER) Organization to exclude the Vacuum Vessel, a core component of the ITER tokamak device, from the scope of regulation under the French and European Nuclear Pressure Equipment Directive (ESPN). This breakthrough ruling marks the beginning of key fusion reactor components breaking free from the regulatory framework derived from traditional fission reactors. Prior to this decision, the ITER Vacuum Vessel had long been classified as nuclear pressure equipment. This classification originated from the management practices of traditional light-water fission reactors, whose underlying logic presumes internal pressure as the primary engineering load on the structure. However...
