Tokyo Electric Power Co., the operator of the Fukushima Daiichi nuclear power plant crippled by the magnitude 9.0 earthquake and tsunami earlier this month, will not be subject to a disclaimer that relieves utilities from paying compensation in connection with nuclear power plant accidents caused by devastating natural disasters, the government's top spokesman said Friday.

Such an exemption from liability is ''impossible under current social circumstances,'' Chief Cabinet Secretary Yukio Edano said at a press conference.

The law on such compensation carries a waiver clause under which the government, rather than a nuclear power plant operator, would pay compensation for damage caused by a nuclear accident resulting from ''an unusually huge natural disaster or a social upheaval.''
