Fusion energy is accelerating through conventional (DEMO) and alternative compact reactor designs, that are potentially faster and cheaper to build (e.g., ARC, STEP). Power exhaust is a key challenge and a potential show-stopper for all these designs. Recent experiment show the key benefits of strongly shaped Alternative Divertor Configurations (ADCs) [1-4], demonstrating their potential as a...
Consistent with the cost and complexity of the ITER full tungsten (W) actively cooled divertor, a comprehensive physics basis has been established over more than two decades (see [1] and references therein). This first-of-a-kind component, of unprecedented size and lifetime requirement, has now moved into the series production phase [2]. This does not mean, however, that physics studies in...
Aiming at building a prototype reactor based on the spherical tokamak (ST) concept by 2040, the Spherical Tokamak for Energy Production (STEP) programme has just entered the second tranche (2025-2032) which focuses on detailed design work. As part of the broader machine design effort, significant progress has been made on the divertor, addressing both physics and engineering challenges....
The stellarator’s steady-state capability offers inherent advantages for fusion power plants (FPP), including disruption-free operation and access to higher densities beyond the Greenwald density limit. However, reconciling particle exhaust and retention while fulfilling mandatory requirements of divertor life-time survival remains a critical challenge for reactor-relevant divertor operation...
The release of the new European DEMO LAR baseline affects the divertor design mainly in terms of input loads (e.g. heat flux) and poloidal profile. Two solutions are investigated, named “long leg”and “short leg” respectively. The long leg is defined and assumed as baseline, while the short leg is under further SOLPS analyses for complete investigations.
For both options, the grazing angle on...
Successful operation of fusion power plant (FPP) depends on a particle and power exhaust strategy which simultaneously facilitates good core performance. “Infinity Two” is Type One Energy’s proposed design for a practical FPP with a robust baseline physics solution and a conservative design margin [1]. It is four-field period, aspect ratio A = 10, quasiisodynamic stellarator with improved...
Optimizing divertor systems and controlling plasma exhaust are critical challenges for reactor-grade magnetic fusion devices such as ITER and future fusion power plants. Achieving these goals requires rapid, accurate modeling of boundary plasma behavior. Traditional high-fidelity edge plasma simulations, while scientifically valuable, are computationally intensive and were not designed for...
High heat loads in fusion reactors still remain as one of the most pressing problems to solve for the realisation of reliable power plants. To this end, divertor components are designed and developed to intercept and manage the large heat fluxes arising from the upstream plasma. Divertor diagnostic systems are utilised in experimental reactors to address the immediate challenges of real-time...
