A plasma confinement configuration of current carrying toroidal plasma with toroidal divertors, which may have the advantages of no major disruption and good confinement, is proposed. The local rotational transform of magnetic field lines and magnetic well in the toroidal divertor are calculated in a cylindrical model. The rotational transform sharply increases near the separatrix, which induces a large shear and significant reduction of the local safety factor. Stabilization of the pressure driven and drift modes by the magnetic well through the edge plasma confinement, and stabilization of the low (m, n) current driven kink and tearing modes by line tying effects in the toroidal divertor are discussed.
