A key issue is whether Washington might agree to build a uranium enrichment facility on Saudi territory, when it might do so, and whether Saudi personnel might have access to it or it would be run solely by US staff in a “black box” arrangement, Reuters reports.

Without rigorous safeguards built into an agreement, Saudi Arabia, which has uranium ore, could theoretically use an enrichment facility to produce highly enriched uranium, which, if purified enough, can yield fissile material for bombs.

Another issue is whether Riyadh would agree to make a Saudi investment in a US-based and US-owned uranium enrichment plant and to hire US companies to build Saudi nuclear reactors.
