TL;DR: In this paper, the authors explored novel concepts for fusion chamber technology that can substantially improve the attractiveness of fusion energy systems, including the potential for: (1) high power density capability; (2) higher plasma β and stable physics regimes if liquid metals are used; (3) increased disruption survivability; (4) reduced volume of radioactive waste; (5) reduced radiation damage in structural materials; and (6) higher availability.

TL;DR: The Advanced Limiter-divertor Plasma-facing Systems (ALPS) program was initiated in order to evaluate the potential for improved performance and lifetime for plasma-facing systems as discussed by the authors.

TL;DR: The final report of a panel set up by the U.S. Department of Energy (DOE) Fusion Energy Sciences Advisory Committee (FESAC) in response to a charge letter dated September 10, 2002 from Dr. Ray Orbach, Director of the DOE's Office of Science was submitted March 5, 2003 as discussed by the authors.

TL;DR: Several high-priority near-term potential research activities to address fusion nuclear science challenges are summarized in this article, including: (1) Research should be preferentially focused on the most technologically advanced options (i.e., options that have been developed at least through the single-effects concept exploration stage, technology readiness levels >3), (2) Significant nearterm progress can be achieved by modifying existing facilities and/or moderate investment in new medium-scale facilities, and (3) Computational modeling for fusion nuclear sciences is generally not yet sufficiently robust to enable truly predictive results to be

TL;DR: In this article, the preliminary design of a helium-cooled, W-5Re alloy, lithium breeder design and the results are reported in this paper, including material selection, helium impurity control, and mechanical, nuclear and thermal hydraulics design.
