The effect of finite-aspect ratio on the impurity contribution to neoclassical ion thermal conductivity is studied. A simple modification to the pure-ion case is obtained with the assumption that the single heavy impurity species is in the Pfirsch-Schlueter regime. It is found that the impurity contribution is larger than the usual approximation: Z/sub eff/ times the pure ion thermal conductivity.
