Research Abstract

In order to clarify the compatibility between liquid breeder for fusion reactors and weld joint of low activation materials, fundamental corrosion tests were conducted on their base metal. Dissimilar weld joints between the low activation materials and 316L steel were fabricated, and their mechanical properties and irradiation properties were examined.
