America's top nuclear regulator voices doubt about the readiness of US reactors to cope with a days-long power outage similar to Japan's Fukushima Daiichi plant.

On Thursday, Nuclear Regulatory Commission (NRC) chairman Gregory Jaczko cast doubt on whether four to eight hours, as required by NRC to manage without power, is enough time, AP reported.

"Four hours doesn't seem to be a reasonable time to restore offsite power if you lost the diesels immediately," Jaczko said.

"In the event there is a station blackout that is externally driven, I'm not convinced that in that situation four hours is enough time to restore offsite power," he added.

Of the 104 nuclear reactors in the US 87 can cope for four hours in a blackout, 14 can cope for eight hours, while three can last for 16 hours.

NRC is looking at whether the blackout rule needs to be updated following Japan's nuclear crisis.

The disaster at the crippled Fukushima nuclear power plant showed that it would take days before electrical power needed to cool down the reactor core and to pump out highly radioactive water can be restored.

The number of the dead and missing from Japan's March 11 quake and tsunami now stands at over 28,000, according to the Japanese National Police Agency.
