The prolonged radiation crisis at Tokyo Electric Power's Fukushima Daiichi plant has stirred fears about nuclear safety, leaving local governments wary about granting approvals to restart reactors taken offline for maintenance.

The government plans safety tests of Japan's reactors and is reviewing its energy policy as the country confronts the prospect of power shortages that could stretch into 2012.

Only 16 reactors are still operating of the 54 commercial reactors available to Japan's nine Japanese utilities and a non-utility electricity wholesaler, Japan Atomic Power Co, at the time the March 11 earthquake and tsunami that triggered the Fukushima crisis.
