The objective of this work is the development of new reduced activation HEAs applicable to next generation small module reactor components by using additive manufacturing (3D printing) method under the support of the 2020 MEXT Innovative Nuclear Research and Development Program. In the fourth presentation, we will present calculation results of effect of alloying elements and magnetism on stacking fault energy.
