TLDR
The ITER PFC design has now reached a rather mature stage following the 2007 ITER Design Review as discussed by the authors, and the key elements of the design, reviews the physics drivers, essentially thermal load specifications, which have defined the concept and discusses a selection of material and design issues.About:

Journal ArticleDOI
Overview of the fusion nuclear science facility, a credible break-in step on the path to fusion energy
Charles Kessel,James Blanchard,Andrew M. Davis,Laila El-Guebaly,Lauren M. Garrison,Nasr M. Ghoniem,Paul W. Humrickhouse,Yue Huang,Yutai Katoh,Andrei Khodak,E. Marriott,Siegfried Malang,Neil B. Morley,George H. Neilson,Juergen Rapp,M.E. Rensink,T.D. Rognlien,A. F. Rowcliffe,Sergey Smolentsev,Lance Lewis Snead,Mark S. Tillack,Peter Titus,Lester M. Waganer,Gregory Wallace,S.J. Wukitch,Alice Ying,Kenneth M. Young,Yuhu Zhai +27 more
TL;DR: In this article, the authors examined the FNSF as part of a two-step program from ITER to commercial power plants, where the first step is considered mandatory to establish the materials and component database in the real fusion in-service environment before proceeding to larger electricity producing facilities.
Journal ArticleDOI
Preparing the scientific basis for an all metal ITER
TL;DR: The use of beryllium, carbon and tungsten as plasma-facing materials (PFMs) in ITER calls for dedicated investigations on their behaviour under the expected particle and power loads and neutron irradiation as discussed by the authors.
Journal ArticleDOI
In-vessel dust and tritium control strategy in ITER
Michiya Shimada,R.A. Pitts,Sergio Ciattaglia,S. Carpentier,C.H. Choi,G. Dell Orco,T. Hirai,A.S. Kukushkin,S.W. Lisgo,J. Palmer,W. Shu,E. Veshchev +11 more
TL;DR: In this article, a baseline strategy for dust and tritium-inventory control and recovery in ITER has been established and preparations are underway for its implementation, suggesting that the in-vessel T-retention could reach the administrative limit of 640 ǫ in as little as ∼2 months of operation.
Journal ArticleDOI
Fabrication of W–Cu functionally graded material by spark plasma sintering method
TL;DR: In this paper, a three-layered (W-25Cu/W-50 Cu/W75Cu, volume fraction) W/Cu functionally graded material (FGM) was synthesized by spark plasma sintering (SPS) at different temperatures for 5 mm under a load of 40 MPa.

Evolution of tungsten degradation under combined high cycle edge-localized mode and steady-state heat loads
Th. Loewenhoff,Andreas Bürger,Jochen Linke,Gerald Pintsuk,A. Schmidt,Lorenz Singheiser,C. Thomser +6 more
TL;DR: In this paper, the results of tests performed in the electron beam facility JUDITH 2 (Forschungszentrum Julich, Germany) on actively cooled tungsten specimens, loaded with edge-localized mode-like thermal shocks (pulse duration 0.48 ms, power densities 0.14-0.55 GW m−2, frequency 25 Hz and up to 1000 000 pulses) were discussed.

TL;DR: In this paper, different aspects of the PWI are assessed in their importance for the initial wall materials choice: CFC for the strike point tiles, W in the divertor and baffle and Be on the first wall.

Characteristics of type I ELM energy and particle losses in existing devices and their extrapolation to ITER
A. Loarte,G. Saibene,R. Sartori,David Campbell,M. Becoulet,L. D. Horton,T. Eich,Albrecht Herrmann,G. Matthews,Nobuyuki Asakura,A. V. Chankin,Anthony Leonard,G. Porter,G. Federici,G. Janeschitz,Michiya Shimada,M. Sugihara +16 more
TL;DR: In this paper, the authors show that ELM energy losses are correlated with the density and temperature of the pedestal plasma before the ELM crash and the timescale of ELM particle fluxes.

Fluctuations and transport in the TCV scrape-off layer
Odd Erik Garcia,J. Horacek,R.A. Pitts,Anders Nielsen,Wojciech Fundamenski,Volker Naulin,J. Juul Rasmussen +6 more
TL;DR: In this article, the authors investigated the particle and radial flux density statistics in the scrape-off layer of TCV plasmas and direct comparison with two-dimensional interchange turbulence simulations at the outer midplane.

Status and physics basis of the ITER divertor
R.A. Pitts,A.S. Kukushkin,A. Loarte,A. Martin,Mario Merola,C.E. Kessel,V. Komarov,Michiya Shimada +7 more
TL;DR: The ITER divertor design is the culmination of years of physics and engineering effort, building confidence that this critical component will satisfy the requirements and meet the challenge of burning plasma operation as discussed by the authors.
