Tokyo Electric Power Co. is considering asking a U.S. utility to verify safety at its idled Kashiwazaki-Kariwa nuclear plant, a senior foreign adviser to the beleaguered utility has said.

It would be the first time a foreign power company has been asked to assess a Japanese nuclear plant.

In Japan only the Nuclear Regulation Authority can check that reactors meet national safety standards. However, an opinion from an ¡°experienced operator¡± would help Tepco, given the public scrutiny it faces, said Dale Klein, chairman of the company¡¯s reform monitoring committee.
