A state-backed bailout fund has agreed in principle on a new turnaround plan for Tokyo Electric Power Co. that features more financial support from the government as Tepco gropes to contain the Fukushima No. 1 nuclear plant disaster, but the plan also assumes reactors will be restarted.

Lenders responded Thursday by extending the utility ¥500 billion.

The Nuclear Damage Liability Facilitation Fund and Tepco declined comment Wednesday on details of the plan, which still needs to be approved by the government, but sources said it was based on the assumption that reactors at Tepco's massive Kashiwazaki-Kariwa plant in Niigata Prefecture will be restarted beginning in July.
