“…A roadmap milestones sequence should be optimized for reaching the goal of an FPP. A reactor study [7–9] could be created to define general characteristics of demonstration FPP and the mission structure would ideally be similar to other (EU, UK, USA) fusion roadmaps. Striving for quantitative milestones and metrics as mileage markers, using quantitative dimensional and dimensionless figures-of-merit and gauging technical readiness levels (TRL), the logic framework for mission milestones and decision points can be outlined.…”

Managing the IFE pathway to fusion electricity will involve management of commericalization scope, schedule, cost and risk. The technology pathway to economical fusion power comprises the commercialization scope. Industry assumes commercialization risk in fielding its own pre-pilot plant research programme for this compact-fusion pathway without the benefit of a federally coordinated IFE research and development programme. The cost of commercializing the mass-production of inexpensive targets and insisting on high reliability, availability, maintainability and inspectability has a major impact on the economics of commercializing fusion power plants. Schedule vulnerability for inertial fusion energy arises from the sensitivity of time-based roadmap stages to uncertainties in the pace of scientific understanding and technology development, as well as to unexpected and inexplicable changes of the budgeting process. Rather than rely on a time-based roadmap, a milestone-based roadmap is maximally appropriate, especially for industry and investors who are particularly well-suited to taking the risks associated with reaching the target milestones provided by the government. Milestones must be identified and optimally sequenced and the necessary resources must be delineated. Progress on the above factors, since the outcomes of recent U.S., U.K. and EUROfusion roadmapping exercises were released, are reported. This article is part of a discussion meeting issue ‘Prospects for high gain inertial fusion energy (part 2)’.

“…A scrape-off-layer (SOL) physics description can start from the SOL particle and power balances Table 1 for SOL parameters is obtained for a stellarator of W7-X size and for a stellarator reactor whose concept consists in enlarging W7-X by a linear factor of about 4 and in doubling its magnetic field [20]. From the values of Pe/21r& one may immediately conclude that divertor plates exploiting the complete toroidal length should have U(0.l m) and 0(1 m) active deposition widths, respectively, for achieving low power Row densities of U(MW/m').…”
