ABU DHABI/KHOBAR, Saudi Arabia- Saudi Arabia has sent a request for information (RFI) to international suppliers to build two nuclear power plants, a first step towards a formal tender, three sources said.

The kingdom is considering building 17.6 gigawatts (GW) of nuclear capacity by 2032, the equivalent of about 17 reactors, making it one of the biggest prospects for an industry struggling after the 2011 nuclear disaster in Japan.

The world's biggest exporter of oil wants to reduce the amount of crude it burns at home to generate electricity so it can sell more of it overseas.

"Saudi Arabia has just sent the request for information to various companies and it is being examined," one industry source told Reuters, adding that firms had about two months to respond.

A second industry source confirmed that Saudi authorities had sent an RFI, which is a request to nuclear vendors to submit non-binding offers to build a nuclear reactor.

"We sent a communication to suppliers," a Saudi official told Reuters without giving details.

One source said Saudi Arabia planned to organise a nuclear conference in Riyadh in coming months.

If a tender proceeds, Saudi Arabia would become the second Gulf Arab state to turn to nuclear power after the United Arab Emirates, which is set to start up its first, South Korean-built reactor in 2018.

Industry sources said Saudi Arabia was reaching out to suppliers from South Korea, China, France, Russia, Japan and the United States for its first two reactors.

French EDF EDF.PA said last month it was in talks with several nations to sell nuclear reactors, including Saudi Arabia. Other potential suppliers are Toshiba-owned Westinghouse 6502.T , Russia's Rosatom, South Korea's Kepco and China's CGN.

Saudi Arabia's nuclear plans have received extra momentum from the kingdom's Vision 2030, an economic reform programme launched last year by Crown Prince Mohammed bin Salman.
