Yong-Su Na,F. Koechl,A. R. Polevoi,C.S. Byun,D.H. Na,Jaemin Seo,Faa Federico Felici,Atsushi Fukuyama,J. Garcia,Nobuhiko Hayashi,C.E. Kessel,T.C. Luce,Jin Myung Park,Francesca Poli,Olivier Sauter,A. C. C. Sips,Pär Strand,A. Teplukhina,I. Voitsekhovitch,Apiwat Wisitsorasak,X. Yuan +20 more
TL;DR: In this paper, the authors report results of benchmarking of core particle transport simulations by a collection of codes widely used in transport modelling of tokamak plasmas. But their analysis includes formulation of transport equations, difference between electron and ion solvers, comparison of modules of the pellet and edge gas fuelling on the ITER baseline scenario.

Yong-Su Na,J. Seo,Yoonji Lee,Gyungjin Choi,Minseo Park,Sang Jeoung Park,S. Yi,Weixing Wang,Min-Gu Yoo,Minsoo Cha,Beom-Seok Kim,Youngho Lee,Hyunsun Han,Boseong Kim,Chanyoung Lee,SangKyeun Kim,SeongMoo Yang,C.S. Byun,Hyun-Seok Kim,Jinseok Ko,Woochang Lee,T.S. Hahm +21 more
TL;DR: In this article , a self-generated current was observed in the KSTAR tokamak, which is a torus-shaped nuclear fusion device that needs an electric current in the plasma to produce magnetic field in the poloidal direction for confining fusion plasmas.
Effect of coherent edge-localized mode on transition to high-performance hybrid scenarios in KSTAR
Youngho Lee,SangKyeun Kim,Jaewook Kim,Boseong Kim,Minseo Park,J. Kwon,M. J. Choi,S. Hahn,M. W. Lee,SeongMoo Yang,Seulchan Hong,Chan-Young Lee,Sangjin Park,C.S. Byun,Hyun-Seok Kim,Ji Hyung Chung,Yong-Su Na +16 more
TL;DR: High-performance hybrid scenarios in KSTAR are characterized by the presence of Coherent Edge-localized Mode (CEM) activity. CEM is related to the increase of particle and heat transport, which leads to pedestal broadening and continuous density decrease. Despite the associated transport increase, CEM activities can induce performance enhancement.

Exploration of one-dimensional plasma current density profile for K-DEMO steady-state operation
TL;DR: In this paper, a one-dimensional current density profile and its optimization process for the Korean demonstration fusion reactor (K-DEMO) steady-state operation are reported, where the impact of self and external heating profiles on those parameters is considered selfconsistently, where thermal power balance and 100% non-inductive current drive are the main constraints during the whole exploration procedure.
