The naturalist John Muir is widely quoted as saying, “When we try to pick out anything by itself, we find it hitched to everything else in the Universe.” While he was speaking of ecology, he might as well have been talking about nuclear fuel.

At the moment, by most accounts, nuclear fuel is in crisis for a lot of reasons that weave together like a Gordian knot. Today, despite decades of assertions from nuclear energy supporters that the supply of uranium is secure and will last much longer than fossil fuels, the West is in a blind alley. We find ourselves in conflict with Russia with ominous implications for uranium, for which Russia holds about a 14 percent share of the global market, and for two processes that prepare uranium for fabrication into reactor fuel: conversion (for which Russia has a 27 percent share) and enrichment (a 39 percent share).

Whether commercial demand for high-assay low-enriched uranium (HALEU) fuel ultimately falls at the high or low end of divergent forecasts, one thing is certain: the United States is not ready to meet demand, because it currently has no domestic HALEU enrichment capacity. But conversations happening now could help build the commercial HALEU enrichment infrastructure needed to support advanced reactor deployments. At the 2022 American Nuclear Society Winter Meeting, representatives from three potential HALEU enrichers, the government, and industry met to discuss their timelines and challenges during “Got Fuel? Progress Toward Establishing a Domestic US HALEU Supply,” a November 15 executive session cosponsored by the Nuclear Nonproliferation Policy Division and the Fuel Cycle and Waste Management Division.

The nuclear industry leaders assembled in Washington, D.C., last week to discuss small modular reactor supply chains agreed that lost generation capacity from the expected retirement of hundreds or thousands of coal power plants over the next decade—a cliff, in one panelist’s words—represents an opportunity that developers of SMRs and advanced reactors are competing to meet.

“I think in total 80 projects are ongoing,” said Boris Schucht, panel moderator and chief executive officer of Urenco Group, as he opened the forum. “Of course not all of them will win, and we will discuss today what is needed so that they can be successful.”

For years, pressure has been building for a commercial path to a stable supply of high-assay low-enriched uranium (HALEU)—deemed essential for the deployment of advanced power reactors—but advanced reactor developers and enrichment companies are still watching and waiting. In contrast, the uranium spot price soared after Sprott Physical Uranium Trust, a Canadian investment fund formed in July, began buying up U3O8 supplies, causing the price to increase over 60 percent, topping $50 per pound for the first time since 2012. Fueled by growing acknowledgment that nuclear power is a necessary part of a clean energy future, uranium is the focus of attention from Wall Street to Capitol Hill.

To nuclear fuel suppliers, today’s operating reactors represent a defined customer base with predictable demands. Utilities must order their next fuel reload far in advance of an outage; enrichers and fabricators work to fill those orders. Adapting such a highly optimized supply chain to accommodate new products—fuels with new materials, claddings, and higher enrichments and burnups—will require alignment between all parties involved to meet the associated research, enrichment, manufacturing, regulatory, transportation, and operating experience needs.

That was the consensus during “Current Accident Tolerant Fuel Environment,” a technical session held on March 9 during the Nuclear Regulatory Commission's four-day Regulatory Information Conference (RIC, March 8-11). The session was chaired by NRC Chairman Christopher Hanson, who was taking part in his first RIC as a member of the commission.
