Tokyo Electric Power Co. is being sued for tens of millions of dollars by eight U.S. Navy sailors who claim that they were unwittingly exposed to radiation from the Fukushima No. 1 nuclear plant meltdowns and that Tepco lied about the dangers.

The sailors aboard the nuclear-powered aircraft carrier USS Ronald Reagan were involved in the Operation Tomodachi disaster relief operations following the March 11, 2011, earthquake and tsunami that devastated the Tohoku region and led to the nuclear catastrophe, according to their complaint filed in U.S. federal court in San Diego on Dec. 21.

Tepco and the Japanese government conspired to create the false impression that radiation leaking from the Fukushima No. 1 plant didn't pose a threat to the sailors, according to the complaint. As a result, the plaintiffs rushed to areas that were unsafe and too close to the facility, exposing them to radiation, their lawyers said.

The Japanese government was "lying through their teeth about the reactor meltdown" crisis, as it reassured the USS Reagan crew that "everything is under control," the plaintiffs' lawyers said in the complaint. "The plaintiffs must now endure a lifetime of radiation poisoning and suffering."

The sailors are each seeking $10 million in damages, $30 million in punitive damages and a judgment requiring the creation of a $100 million fund to pay for their medical monitoring and treatments.

"We can't comment as we have not received the complaint document yet," Yusuke Kunikage, a Tepco spokesman, said Thursday. "We will consider a response after examining the claim."

In July, the Nuclear Damage Liability Facilitation Fund took control of Tepco in return for a ¥1 trillion capital injection after the disaster left the utility on the brink of bankruptcy. The utility received ¥1.4 trillion in state funds to compensate those affected by the disaster.
