Core-edge integrated modeling of ARC: on the effect of impurity transport and detachment conditions
New modeling suggests Argon seeding is key for high-power, detached divertor operation in ARC fusion reactor.
Integrated modeling of the ARC fusion reactor's H-mode scenarios indicates that Argon seeding can enable high-performance operation approaching 1 GW of fusion power.
The research demonstrates that Argon seeding allows for divertor temperatures below 2 eV while maintaining fusion power levels between 750-1000 MW, with separatrix density being a critical factor.
While Neon seeding was explored, it resulted in lower fusion power (600-850 MW) and less stable H-mode access due to core impurity accumulation.
