Description
Summary:The numerical analysis of the demonstration fusion reactor Demo‐CREST has been carried out; this analysis focuses on impurity seeding. Several design activities for DEMO have been carried out; however, its detailed divertor plasma analysis remains to be carried out. Therefore, in this study, we discuss the possibility of neon puffing in Demo‐CREST to decrease the power load to the divertor plate by using the B2‐EIRENE code. It has been shown that the radiation power loss by neon increases with upstream plasma density and that the peak power load to the divertor plate comes close to the allowable level by using the preliminary divertor configuration (© 2010 WILEY‐VCH Verlag GmbH & Co.
