[en] In this paper, we present a new neoclassical transport calculation method for general toroidal plasmas including quasi-symmetric configurations based on the moment approach with the DKES (Drift Kinetic Equation Solver) mono-energetic transport coefficients. The Onsager symmetric matrix, expressing parallel viscosity and the radial transports in terms of parallel flows and thermodynamic forces, is obtained from the numerical calculating results of the drift kinetic equation with the pitch angle scattering operator. And then, the radial transports and parallel flows are derived by combining this matrix, the friction-flow relation and the parallel momentum balance equations. To demonstrate the validity and the effectiveness of this method in which the momentum conservation is completely included and the treatment of multi-ion-species plasmas is easier, we present here how the intrinsic ambipolarity and the impurity accumulation in an axisymmetric limit, which are predicted by analytic theories, are obtained in this numerical calculation.
