ARIES-RS divertor system selection and analysis
The ARIES-RS divertor system is selected and analyzed. A radiative divertor approach using Ne as the radiator is chosen to reduce the maximum heat flux to B6 MW m. A 2 mm W layer is used to withstand surface erosion allowing a design life close to 3 full-power-years. This W coating on the V-alloy structure is castellated to meet structural design limits. A detailed description of the calculated...
متن کاملFracture and Creep in an All-Tungsten Divertor for ARIES
The ARIES project is currently proposing an all-tungsten divertor for their tokamak designs. In designing such a component, fracture will be a critical failure mechanism, due to the limited ductility of the tungsten. Hence, this paper presents a series of fracture mechanics-based analyses to demonstrate the feasibility of using an alltungsten divertor in a commercial device. The analyses presen...
متن کاملDesign Optimization of High-performance Helium-cooled Divertor Plate Concept
A helium-cooled plate-type divertor design concept has being proposed within the framework of the ARIES power plant study. W tiles are used as sacrificial armor, W-alloy as main structural material and advanced ODS (oxide dispersion-strengthened) steel as the coolant manifold. An impinging jet cooling scheme is employed to enhance the heat transfer characteristics of the concept in the high hea...
متن کاملDivertor Configuration and Heat Load Studies for the Aries-cs Fusion Power Plant
The critical issue of divertor configuration for heat and particle flux control in a conceptual ARIES compact stellarator (CS) reactor is addressed. The goal is to determine a divertor location and geometry with a peak heat load of not more than 10 MW/m2 for a CS equilibrium based on the configuration to be used in the NCSX experiment, optimized for high beta (6.4%) and designed for low alpha-p...
متن کاملNational Spherical Torus Experiment Liquid Lithium Divertor
Recent NSTX high power divertor experiments have shown significant and recurring benefits of solid lithium coatings on PFC’s to the performance of divertor plasmas in both Land Hmode confinement regimes heated by high-power neutral beams. The next step in this work is installation of a liquid lithium divertor (LLD) to achieve density control for inductionless current drive capability (e.g., abo...
