Impurity seeded radiative power exhaust solutions for ITER

Nuclear Fusion, 1996
The injection of impurities into the scrape-off layer (SOL) to stimulate radiative power exhaust from the mantle and SOL/divertor of the International Thermonuclear Experimental Reactor (ITER) is investigated. Intermediate Z impurities (e.g. argon to krypton) are able to radiate more than two thirds of the plasma heating power, without significant ...

Impurity Seeding with Dust Injection in Tokamak Edge Plasmas

Contributions to Plasma Physics, 2012
AbstractImpurity seeding of tokamak edge plasmas in the form of dust is modeled using the recently coupled DUSTT/UEDGE code. The effects on edge plasma performance due to lithium and carbon dust continuously injected at different poloidal locations in NSTX and ITER are modeled.

Influence of impurity seeding on plasma burning scenarios for ITER

Fusion Engineering and Design, 2016
Abstract ITER expects to produce fusion power of about 0.5GW when operating with tungsten (W) divertor and beryllium (Be) wall. The influx of W from divertor can have significant influence on the discharge performance. This work describes predictive integrated numerical modeling of ITER discharges using the COREDIV code, which self-consistently ...

Reduced Models of Impurity Seeded Edge Plasmas

Contributions to Plasma Physics, 2008
AbstractThe reduced descriptions of the distribution of impurities over ionization states, radiation losses and plasma dynamics are reviewed. Two and three most important ion approximation for light impurities and continuous descriptions of heavy impurities are discussed. Reduced descriptions of atomic processes like ionization, photo‐ and dielectronic

Influence of impurity seeding on the plasma radiation in the EAST tokamak

Plasma Science and Technology, 2018
Plasma radiation characteristics in EAST argon (Ar) gas and neon (Ne) gas seeding experiments are studied. The radiation profiles reconstructed from the fast bolometer measurement data by tomography method are compared with the ones got from the simulation program based on corona model.
