When the first reports of the deal started emerging, a nuclear nonproliferation expert at the national security think tank Foundation for Defense of Democracies warned it would be "bad".

"Congress should block it," Andrea Stricker, posted on X.

"If it does not, one hopes the policy will be reversed by a subsequent administration before too much damage is done in terms of watering down safeguards, setting negative precedents for other states, and failing to contain the spread of enrichment and reprocessing—which we just put back in the box in Iran via force," she added.

Stricker called the 2009 deal with Saudi Arabia's neighbour, the United Arab Emirates - in which the UAE does not produce its own fuel and accepts a host of other restrictions - "the gold standard", and warned that the agreement to be announced would "demolish" that standard.

Some fear this deal could trigger a nuclear arms race in the Middle Eastpublished at 17:59 BST

This deal is controversial.

The reason why the US is doing this is two-fold. It has a commercial interest, because American firms are going to make money out of it.

But partly it's to keep Saudi Arabia within its strategic sphere of interest.

The United Arab Emirates got the South Koreans to help them in this area, as well as the US.

If Washington turned down a Saudi request for help with their civil nuclear programme then the Saudis could turn to the Chinese to help them.

Saudi Arabia already has a nascent civil nuclear programme, and its big regional rival just across the Gulf is the Islamic Republic of Iran which, as we know, has a very advanced one.

This deal comes as a war is raging nearby in the Gulf and many countries are saying to Iran, you can't enrich your own uranium or you can't be trusted to.

The fear is that if Saudi Arabia starts enriching its own uranium, that could just encourage hardliners in Iran to secretly race to build a bomb.

It could also, potentially, trigger a nuclear arms race in the region with Egypt and Turkey stepping up their own programmes.

The deal set to be announced the US and Saudi Arabia will focus on nuclear power generation, according to CBS.

Saudi Arabia generated an estimated 453 terawatt hours (TWh) of electricity in 2023, with 62% from natural gas, 38% from oil, and less than 1% from renewables, according to data from the US Energy Information Administration (EIA).

Saudi Arabia currently has no nuclear power plants, but, in September 2023, its energy minister reiterated the country's intentions to build one.

The US-Saudi relationship has undergone radical change in the last few years.

Four years ago this month, former President Joe Biden gave an awkward fist bump to the Saudi Crown Prince Mohammed bin Salman.

It came after Biden previously vowed to make the Gulf nation a "pariah" following US intelligence conclusions that the crown prince personally ordered the killing and dismemberment of US-based journalist and critic Jamal Khashoggi in Turkey.

But as the Russia-Ukraine war sent oil prices soaring, Biden turned to Saudi Arabia, the world's leading oil exporter, to help stabilise oil prices. At a future meeting, the pair shook hands but a warm relationship was slow to materialise.

Since returning to the White House, President Donald Trump has worked to cultivate a closer relationship. One of his first major foreign trips was to Saudi Arabia in May 2025 - where Saudi companies reportedly pledged $600bn in investment.

Last November, Trump warmly welcomed bin Salman to the White House with a personal greeting on a red carpet, a military flyover, and a tour of the presidential mansion. The president also speaks very fondly about Saudi leaders, frequently claiming that King Salman bin Abdulaziz told him the US was "a dead country" under Biden.

In recent months, Saudi Arabia has found itself in the firing line of Iranain attacks, and its energy exports have been disrupted, after the US launched attacks on Iran.

Talks on the United States and Saudi Arabia co-operating on a civil nuclear programme go back as far as 2008.

Under the Bush administration, the two countries signed a nonbinding memorandum of understanding (MoU), with the US saying it would assist the Gulf kingdom to develop civilian nuclear energy but that Saudi Arabia has stated it intended to import nuclear fuel and would not pursue "sensitive nuclear technologies".

Here's some of the key milestones since then:

• From 2017 to 2019, the US granted seven American companies authorisation to engage in "civil nuclear discussions" with Saudi Arabia
• However, in 2020 the US Government Accountability Office reported that the two nations had "not made significant progress" due to "persistent differences" over conditions including restrictions on enrichment
• In 2022, the US and Saudi signed a new MoU on "the exchange of technical information and cooperation in nuclear safety matters"
• In 2023, the Wall Street Journal reported that the US was considering a US-run uranium enrichment operation within Saudi Arabia
• In November 2025, the US and Saudi Arabia signed a joint declaration which the Trump administration said "builds the legal foundation for a decades-long, multi-billion-dollar nuclear energy partnership"

One of the key points of the deal, according to reports in US media, is that Saudi Arabia may be allowed to enrich uranium itself rather than relying on imported fuel.

This would reportedly take place at a US-built uranium enrichment facility within Saudi Arabia, and stands out as a key difference compared to the US's nuclear deal with the United Arab Emirates.

Under this 2009 agreement, the UAE does not produce its own fuel and also faces a number of other restrictions.

Washington and Riyadh are set to announce they have reached a deal that would see Saudi Arabia able to develop nuclear power for the first time.

The two countries have reached a commercial agreement for US companies to run nuclear power plants on Saudi Arabian soil, a regional official familiar with the agreement told the BBC's US partner, CBS News.

An official announcement is expected later today.

The deal may allow the Saudis to enrich their own fuel for nuclear reactors, CBS reports.

The companies involved have not yet been disclosed, but Congress would need to be consulted, according to CBS.

The BBC has asked the White House for comment.
