“…The optimum build of the reactor and its performance are determined by various limits imposed by plasma physics and engineering technology. Physics and technology applied to the ITER designs should be improved to design a tokamak fusion reactor that can produce electricity at a competitive cost [1][2][3][4][5][6], which includes better plasma pressure, density, confinement, and divertor heat management; advancements in engineering implementations such as the maximum allowable magnetic field at the toroidal field (TF) coil; advanced materials for blankets and shields, and innovations in tritium breeding blanket concepts, power handling, and high-temperature Brayton thermal cycle.…”

“…A tokamak systems analysis coupled with neutron transport calculations [6,7] can address not only plasma physics and engineering constraints, but also neutronic constraints. Such an analysis can play a key role in the determination of self-consistent system parameters and the optimum build of a small tokamak fusion reactor at a minimum cost.…”

An inventive method was applied to determine the minimum major radius, R0, and the optimum build of a tokamak fusion reactor that simultaneously meets all physics, engineering, and neutronics constraints. With a simple cost model, tokamak systems analyses were carried out over ranges of system parameters to find an optimum build of a tokamak fusion reactor at minimum cost. The impact of a wide range of physics parameters and advanced engineering elements on costs were also addressed. When a central solenoid was used to ramp up a plasma current, design solutions with a cost of electricity (COE) between 109 and 140 mills/kWh, direct capital cost between 5000 and 6000 M/USD, and net electric power, Pe between 1000 and 1600 MW could be found with a minimum R0 between 6.0 and 7.0 m, and fusion power, Pfusion between 2000 and 2800 MW. When the plasma current was driven by a non-inductive external system, the system size and costs could be reduced further; a COE between 98 and 130 mills/kWh, direct capital cost between 4000 and 5000 M$, and Pe between 1000 and 1420 MW could be found with a minimum R0 between 5.1 and 6.7 m, and Pfusion between 2000 and 2650 MW.
