Toshiba-owned Westinghouse is in talks with other U.S-based companies to form a consortium to bid in a multibillion-dollar tender for two nuclear power reactors in Saudi Arabia, three industry sources said.

Saudi Arabia, the world's top oil producer, sent a request for information (RFI) to reactor builders worldwide last month in a first step toward opening a formal tender. A nuclear newcomer, it wants to use atomic power to generate electricity at home so it can export more crude.

Taking part in the tender would be a major step for reactor builder Westinghouse after it went into chapter 11 bankruptcy this year.
