Impurity gas injection effects were investigated in ELMy H-mode and reversed shear plasmas from viewpoints of divertor heat flux and power balance. In ELMy H-mode discharges with Ar seeding, the pedestal stored energy and good energy confinement was maintained as the radiation fraction, P_<rad>/P_<net> was increasing up to 0.88. The ELM energy deposition to the divertor normalized by the pedestal stored energy decreased moderately as a function of P_<rad>/P_<net> while ELM frequency was reduced significantly. With Ne seeding and moderate D_2 gas puffing rate, the radiative divertor plasma was produced in a reversed shear plasma with good plasma confinement H_<89> ~ 1.8. Radiation loss profiles and divertor heat flux profiles clearly revealed the divertor plasma detachment due to X-point MARFE.
