Designing Radiation Resistance in Materials for Fusion Energy
TL;DR: In this article, three fundamental options for designing radiation resistance are outlined: Utilize matrix phases with inherent radiation tolerance, select materials in which vacancies are immobile at the design operating temperatures, or engineer materials with high sink densities for point defect recombination.

TL;DR: In this paper, the main focus is on the main design driver, steady state power fluxes in the DT phases, obtained from simulations using the 2-D SOLPS-4.3 and SolPS-ITER plasma boundary codes, assuming the use of the low Z seeding impurities nitrogen (N) and neon (Ne).

TL;DR: In this paper, the authors defined the requirements for edge localized mode (ELM) control and the application of ELM control methods both for high fusion performance DT operation and non-active low-current operation in ITER.

Edge-localized-modes in tokamaksa)
TL;DR: In this article, the authors show that when the gradient in the H-mode transport barrier grows to exceed the MHD stability limit, the ELM instability grows explosively, rapidly transporting energy and particles onto open field lines and material surfaces.

TL;DR: In this paper, the poloidal variation of the parallel flow has been measured by moving the contact point of a small circular plasma onto limiters at different poloidal angles, and the resulting variations of flow are consistent with the existence of a poloidally localized enhancement of radial transport concentrated in a 30° sector near the outboard midplane.

Codeposition of deuterium with ITER materials

TL;DR: In this paper, the authors compared the levels of retention in codeposited layers of each of the three ITER materials (C, Be and W) and presented scaling laws, based on the conditions during the codeposition process (surface temperature, incident particle energy and ratio of the depositing fluxes), to allow prediction of expected retention under ITER conditions.

An empirical scaling for deuterium retention in co-deposited beryllium layers
TL;DR: In this paper, a scaling equation was developed to predict the retention in Be co-deposits formed in PISCES-B as a function of the layer formation conditions, and relatively good agreement was found with the prediction of the scaling equation.
