An integrated design framework for future nuclear fusion power reactors
Nuclear fusion has long been touted as a future source of low-carbon energy. Whether or not fusion energy will be feasible, let alone commercially viable, remains a subject of research and development. Tokamaks are the most mature path to fusion energy, and two key steps are broadly seen as …

Computational design of interfaces : mitigating He damage in nuclear fusion applications
In order for nuclear fusion to be a feasible source of energy, materials must be developed that are resistant to the damaging byproducts of a fusion reaction. One of these byproducts is He, that is implanted into the plasma facing wall of the reactor. Once implanted, it causes irreparable damage …

Sputter deposition and plasma modification of tungsten alloys for nuclear fusion applications
The ITER reactor aims to be first thermonuclear fusion device to demonstrate net fusion power. Critical plasma-facing components in the reactor will be made of tungsten, but helium plasma irradiation is known to embrittle tungsten metal. A future reactor will therefore need an alternative material …
