NNN Daily Brief: May 31, 2026

Today’s lead story is DOE opening talks with Oklo on plutonium fuels. The headline matters because it pushes a long-running fuel-cycle question into active negotiations.

Top Story

DOE opens talks with Oklo about plutonium fuels. Nuclear Street reports that Oklo has been selected by the U.S. Department of Energy to open negotiations under the Surplus Plutonium Utilization Program.

That could shape how surplus plutonium is handled, and whether it becomes part of an advanced-reactor fuel pathway.

In Brief

  • No other stories cleared today’s ingest cut. The raw pipeline surfaced one item, so the day’s coverage is centered on this fuel-cycle development.

One Thing to Know

In nuclear markets, fuel policy can be as consequential as a reactor announcement: without a supply pathway, deployment plans slow down quickly.
