Impurity seeding has been studied for a carbon-free divertor configuration in ITER using edge/divertor SOLPS code simulations. For high power DT operation, simulations have been performed for varying throughput, power, pumping speed, impurity seeding

The paper presents a review of the development of edge plasma modeling at ITER and of its interaction with the evolving divertor design. The SOLPS (B2-Eirene) code has been developed for, and applied to, the evaluation and the design of the ITER dive

A systematic numerical study of the deposition of Be and C atoms on the ITER main chamber first mirrors and their erosion due to fast D(T) atoms has been carried out. The calculations are based on Monte-Carlo neutral transport modelling (with the EIR

ITER divertor and edge modelling with the ITER B2-EIRENE code including neutral–neutral and molecule–ion collisions has been applied to the ITER reference divertor plasma with the reference low- l i equilibrium. The scaling of key parameters such

The throughput requirements that the ITER fuelling system must satisfy are estimated considering the major system functions. The ELM pace-making and control of the divertor power loading are found to be the most demanding. The total required throughp

The integrated core-pedestal-SOL model is applied to the simulation of a typical DEMO operation. Impurity seeding is used to reduce the power load on the divertor to acceptable levels. The influence on long-pulse operation of impurity seeding with va

A statistical approach originally proposed to determine the underlying transport mechanism from a regression analysis of experimental measurements of the power deposition width at the targets is tested against 2D modelling data. The method is found t

An improved model for triggering edge localized mode (ELM) crashes is developed for use within integrated modelling simulations of the pedestal and ELM cycles at the edge of H-mode tokamak plasmas. The new model is developed by using the BALOO, DCON

A model is developed for use in integrated modelling codes to predict the AQ1 height, width and shape of the H-mode pedestal as well as the frequency and width of edge localized modes (ELMs). The model for the H-mode pedestal in tokamak plasmas is ba
