摘要：

Ion transport in the region close to the magnetic axis in tokamaks is investigated by solving the drift kinetic equation with the proper orbit topology taken into account. It is found that ion thermal conductivity remains finite in that region. The scaling of the thermal conductivity can be understood in terms of st random walk process in units of the poloidal flux.
