PSI issues at plasma facing surfaces of blankets in fusion reactors
TL;DR: In this paper, the effects of the first wall on core plasma performance are briefly discussed in terms of hydrogen isotope recycling and reflection of synchrotron radiation, and erosion rates of the blanket first wall made by low-activation materials are not acceptable considering their thickness.

A neutronic investigation of He-cooled liquid Li-breeder blankets for fusion power reactor
TL;DR: In this article, a he-cooled liquid lithium blanket has been optimized in terms of the tritium breeding ratio (TBR) and the neutron shielding, and the results were used in determining the lifetime of a natural lithium breeder.

Optimal configuration of neutron reflector in He-cooled molten Li blanket
TL;DR: In this paper, the optimal configuration of a He-cooled molten Li (HCML) blanket in terms of tritium breeding ratio (TBR) was found for a graphite-reflected HCML blanket and the impact of the Li-6 composition on TBR was investigated.
Journal ArticleDOI
Neutron wall loading of Tokamak reactors
TL;DR: In this article, the authors reported the determination of the range of Γn for economically competitive fusion power plants based on the analysis that couples the MHD stability physics results to a system design code.

The spherical tokamak path to fusion power
TL;DR: The low-aspect-ratio tokamak or spherical torus (ST) approach offers the two key elements needed to enable magnetic confinement fusion to make the transition from a government-funded research program to the commercial marketplace: a low-cost, low-power, small-size market entry vehicle and a strong economy of scale in larger devices.
