Steve Witkoff, Trump’s special envoy for peace, and Jared Kushner quietly traveled to Oak Ridge National Laboratory and the adjacent Y-12 National Security Complex in Tennessee last week for a deep-dive consultation with roughly 100 technical experts. The visit, confirmed by two US officials, focused on uranium processing, centrifuge technology, and the practical mechanics of what a nuclear agreement with Iran would actually require on the ground.

The timing matters. Just one week before the Oak Ridge trip, a preliminary 60-day Memorandum of Understanding was discussed with Iranian counterparts, covering a ceasefire extension, reopening the Strait of Hormuz, and the thorniest issue of all: what happens to Iran’s enriched uranium stockpile and its future enrichment capacity.

What happened at Oak Ridge

Oak Ridge is not a random pit stop. The facility in eastern Tennessee has been at the center of American nuclear science since the Manhattan Project. Y-12, which sits adjacent to the national laboratory, is where the US maintains its uranium processing expertise and houses some of the country’s most sensitive nuclear security operations.

Witkoff and Kushner sat with Department of Energy specialists to walk through the technical realities of disposing of and verifying Iran’s enriched uranium stockpile. The consultation involved around 100 experts. These aren’t just physicists. Verification of nuclear materials requires specialists in isotope analysis, facility inspection protocols, centrifuge engineering, and supply chain monitoring.
