Catalyst with Shayle Kann

Building a domestic nuclear fuel supply chain

Catalyst with Shayle Kann

Show Notes

Even as momentum grows for U.S. nuclear, the fuel supply chain is often overlooked. This dynamic is shifting as the industry wakes up to critical choke points and a heavy reliance on countries like Russia for enrichment. As America aims to reduce geopolitical dependency in energy, fixing these domestic gaps has become a strategic priority.

In this episode — a companion to a separate episode of Catalyst focused on nuclear waste — Shayle Kann speaks with Scott Nolan, the CEO of General Matter. The company is focused on enrichment, one of the most acute risk areas in the supply chain. Shayle and Scott also discuss the big-picture state of nuclear fuel, from mining to advanced reactor requirements.

The two cover topics like:

The five-step nuclear fuel supply chain

America’s continued reliance on Russian enrichment:

The history of enrichment decline in the US

The "chicken or egg" problem for advanced reactors

Distinctions between LEU and HALEU fuel

Enrichment’s toll-service business model

The strategic importance of General Matter’s enrichment facility in Paducah, Kentucky

As data center-driven load growth continues to rise, hyperscalers are turning to natural gas – both in front of and behind the meter — to secure power. But whether the natural gas pipeline system has the bandwidth to support this surging demand remains far from certain.

Of all the concerns surrounding the AI boom, data center water usage tops the list. Opponents claim that massive hyperscaler facilities threaten local drinking supplies and drain aquifers. Proponents say data centers use a negligible amount of water, at least compared to agriculture or conventional power generation sources.

It’s been a wild few years for grid-scale batteries in Texas. At the start of the decade, the Lone Star State was home to roughly 200 megawatts of battery capacity. Today, that number has skyrocketed to seventeen gigawatts…with at least five more gigawatts expected to come online by the end of 2026.
