Comparisons and physics basis of tokamak transport models and turbulence simulations
, 2000 The predictions of gyrokinetic and gyrofluid simulations of ion-temperature-gradient (ITG) instability and turbulence in tokamak plasmas as well as some tokamak plasma thermal transport models, which have been widely used for predicting the performance ...

, 2008 A self-consistent analysis of the currents in a tokamak yields the result that the parallel neutralizing current is given simply by the sum of currents commonly called the bootstrap current and the Pfirsch-Schlueter current. An expression is given relating the parallel and perpendicular pressure gradient induced species flow velocities to the total ...

The physics of an ignited tokamak [PDF]
Fusion Engineering and Design, 1991 A next step device which can demonstrate long burn with a high probability of success is possible, without speculating on the accumulation of favorable effects and ignoring the other ones. From the data base available today this appears possible only with large devices such as NET, ITER or JIT.

Tungsten melting and erosion under plasma heat load in tokamak discharges with disruptions
Nuclear Materials and Energy, 2017 Full tungsten poloidal and mushroom limiters were tested in series of experiments with disruptions in the T-10 tokamak. Significant melting, formation of small craters and erosion of the tungsten limiter have been observed after ∼400 discharges with ...

Mechanical model for a full fusion tokamak enabled by supercomputing
Nuclear FusionDetermining stress and strain in a component of a fusion power plant involves defining boundary conditions for the mechanical equilibrium equations, which implies the availability of a full reactor model for defining those conditions.
