초록

Deuterium-tritium reaction is the most promising one in term of the highest nuclear fusion cross-sectionfor the reactor. So it is one of urgent issues to develop materials and components that are simultaneouslyresistant to high heat flux and high energy neutron flux in realization of the fusion energy. 2.45 MeVneutron production was reported in D-D reaction in KSTAR and regarded as beam-target is the dominantprocess. The feasibility study of KSTAR to wide area neutron source facility is done in term of D-D and D-Treactions from the empirical scaling law from the mixed fast and thermal stored energy and its projection to cases of heating power upgrade and DT reaction is done
