The French Authority for Nuclear Safety and Radiation Protection (ASNR) has published a decision on how it will be regulating ITER, opting to approve the organization’s request to exclude its vacuum vessel from French and European pressure equipment rules.

Until now, ITER’s vacuum vessel has been classified as nuclear pressurized equipment, a designation given to a system under pressure that contains activated elements, which was derived from fission light water reactor practice where pressure is the dominant load.
