Riyadh plans to announce at the beginning of March who will construct the first two of up to 16 reactors, and negotiations are underway with the United States for its agreement to export technology needed for their construction, AFP reported.
Democratic Senator Ed Markey, of Massachusetts, said any deal is "almost certain" to require a non-proliferation accord, known as a "123 agreement," that is designed to prevent the spread of nuclear weapons.
"Previous US efforts to conclude a 123 agreement with Saudi Arabia have been unsuccessful because of its long-standing refusal to commit to foregoing any uranium enrichment or spent-fuel reprocessing on its territory – the so-called... 'gold standard' for 123 agreements," Markey, of the Senate Foreign Relations Committee, said in a letter to Secretary of State Rex Tillerson and Energy Secretary Rick Perry.
His concerns come with US-Iran tensions high over the civil nuclear program of Iran.
US President Donald Trump has threatened to tear up a 2015 global pact under which Iran agreed to curb its nuclear program in exchange for a lifting of sanctions.
Both Washington and Riyadh have complained of Iran's "destabilizing" acts in the Middle East.
Markey said Saudi Arabia's "unwillingness" to commit to a "gold standard" 123 agreement "is particularly concerning in light of comments made by Saudi officials and members of the royal family suggesting that a nuclear program may be as much for geopolitical purposes as for electricity generation."
Competition from other countries
According to US media, Saudi Arabia's Crown Prince Mohammed bin Salman – the main driver of a more aggressive regional push by the kingdom – is to visit the United States in early March to meet with Trump.
The visit has not been officially confirmed by either country.
Ties between the kingdom and Washington have strengthened since Trump assumed office early last year. His first official trip abroad was to Saudi Arabia, which is trying to diversify its oil-based economy and energy sources.
In his letter dated Monday, Markey asks the two US officials to explain "the impetus for renewed discussions on a nuclear cooperation agreement between the United States and Saudi Arabia."
He also questions whether the kingdom asked the US administration "to consider concluding a 123 agreement that does not include the gold standard or did the Trump administration independently decide to consider this prospect?"
In mid-February on the sidelines of a conference in Munich, Saudi Arabia's Foreign Minister Adel al-Jubeir, speaking with US television channel CNBC, suggested Riyadh could turn to other countries if the Trump administration did not support its civil nuclear program.
Besides the US company, Westinghouse, Russian, French, Chinese and South Korean firms have all been seeking the Saudi contracts.
Markey on Tuesday said that Perry, who will reportedly meet Saudi officials including Energy Minister Khaled al-Faleh in London, must brief him, and the rest of the Foreign Relations Committee, "on what transpired during his trip" upon his return.
"And the Trump administration must explain more fully... why it is considering compromising" in a potential 123 agreement with Saudi Arabia.
