Western Nuclear Industry Bounces Back With Progress Across Small And Large Designs

After last month's report from Goldman Sachs on the ongoing global nuclear renaissance listed only a couple headlines for the western nuclear industry, June saw a significant bounce back as the industry saw progress across the microreactor landscape and the larger SMR and national grid-scale designs.

The Micro Reactor Industry saw a huge achievement with the exceeding of the goals set by President Trump in the 2025 Executive Orders, with four microreactor designs obtaining criticality by July 4th.

The AP1000 reactor, which is emerging as America's flagship grid-scale design, also saw significant multi-billion-dollar support from the Department of Energy when the Office of Energy Dominance Financing put up a potential $17.5 billion in funding for long-lead components and other pieces/parts of the reactor supply chain.

Goldman Sachs analyst Brian Lee reviews headlines across the nuclear industry for June.

Uranium pricing and volume trackers

Spot pricing remained broadly range-bound. Spot U3O8 prices softened through early June, easing from ~$86/lb to the mid‑$84s before recovering into the mid‑$85s through the middle of the month. Prices drifted modestly lower again toward month‑end, finishing June around ~$85/lb and remaining largely unchanged through early July. Market activity was subdued throughout the period, with trading volumes concentrated in a limited number of transactions and overall price movements remaining relatively narrow.

Term pricing firm. Term pricing strengthened through June, with the long‑term price increasing to $94/lb by end of June from $93/lb at the start of the month, reinforcing the view that longer term pricing remains well supported despite softer spot market activity. Market engagement continued across the term market, with utilities evaluating mid‑ and long‑term supply requirements and several new contracting opportunities emerging. Overall, longer‑dated price indicators remained resilient, with forward prices continuing to reflect supportive long‑term market fundamentals.
