The government is discussing a radical overhaul of the nuclear power sector that would combine the nation's 50 operating reactors into a single company to rebuild an industry that's been effectively halted by the Fukushima disaster that started in March 2011.

The company would be owned by the nine regional utilities, along with wholesalers Japan Atomic Power Co. and Electric Power Development Co., while the government and reactor makers would give financial and technical support, Taku Yamamoto, who chairs the Liberal Democratic Party's energy committee, said in an interview.

Part of the profit from sales of the new company's electricity would be funneled toward the cleanup of the Fukushima No. 1 power plant and victim compensation, which combined may cost more than ¥11 trillion. The plan would keep Tokyo Electric Power Co. alive to shoulder Fukushima costs.
