To evaluate a bootstrap-current-profile quickly, a simple method has been developed with a novel approximation. This results in that all of the neoclassical diffusion coefficients for the gradient become the polynominals only in variables of inverse aspect-ratio, ε, effective charge, Zeff and collisionality, ν*, in the whole range of variables. The resultant current profile is well reproduced from ITER benchmark with transport code including the case with internal-transport-barrier. This method is applied to a commercial reactor, VECTOR, low-aspect-ratio tokamak reactor. The fraction of bootstrap-current, IBS/Ip, are evaluated as: ∼55%, ∼60% and ∼100% for the normal-shear, weakly-reversed-shear and strongly-reversed-shear (with current-hole) plasmas, respectively.
