3 Nuclear Stocks After The NRC X Energy Win Investors Should Watch

The Nuclear Regulatory Commission’s green light for X-energy’s Xe-100 reactors at Dow’s Seadrift site turns advanced nuclear from theory into a testable reality, and that shift matters for your portfolio. Early winners in small modular reactors and related technologies could gain new customers, partners or orders, while weaker stories risk being exposed. This piece unpacks three stocks exposed to this news and explains why each one might deserve a closer look.

The stocks covered below are just a starting sample, and the full screen surfaced 7 more companies with equally compelling narratives that are not included here. If you want to identify, compare, and analyze the higher conviction advanced nuclear opportunities first, head straight to the Advanced Nuclear & SMR Developers screener.

X-Energy (XE)

Overview: X-Energy develops advanced small modular nuclear reactors and TRISO fuel, aiming to supply power and high-temperature heat for industrial and data center sites.

Operations: X-Energy generates about US$150 million from Electric Equipment, with roughly US$165 million of revenue tied to customers in the United States.

Market Cap: US$4.24b

X-Energy provides direct exposure to advanced nuclear deployment, with its Xe-100 SMRs, TRISO fuel and Dow’s Seadrift industrial project all closely aligned with the screener theme. The stock offers pure-play access to reactors and fuel, but remains unprofitable and trades at a price-to-sales multiple of 21.3, so much depends on how one unresolved execution bottleneck affects future project economics.

With that execution question hanging over X-Energy, the DCF valuation analysis for X-Energy shows how much of today’s rich P/S multiple already assumes clean delivery.

Terrestrial Energy (IMSR)

Overview: Terrestrial Energy develops Generation IV small modular nuclear plants built around its Integral Molten Salt Reactor technology for industrial and power customers.

Market Cap: US$301 million

Terrestrial Energy fits into the Advanced Nuclear & SMR Developers theme, and the favorable analyst narrative on Simply Wall St focuses on how its IMSR ecosystem could convert current development work into future contracted fuel and core-unit revenue.

"The DOE supported TETRA test reactor and TEFLA fuel line pilots are set up to generate operating data and define commercial fuel salt production processes that can be used across multiple IMSR plants, which could support more predictable fuel salt margins and a longer lived earnings stream from follow on contracts."

The key issue for Terrestrial Energy is how a tightly linked sequence of licensing and project decisions may ultimately affect unit economics.

If that sequence of decisions is what you are weighing, the full narrative for Terrestrial Energy explains how licensing risk, capital needs and customer demand could be converging.

NuScale Power (SMR)

Overview: NuScale Power develops small modular nuclear reactors and related services, providing its NuScale Power Module technology and end to end plant support for customers.

Operations: NuScale Power currently generates about US$3 million of revenue from electric utility services, all reported from customers in the United States.

Market Cap: US$2.18b

NuScale Power sits right in the Advanced Nuclear & SMR Developers theme. Its reactor design and service offering are built specifically for modular nuclear deployment at industrial sites and potential future data centers. The analyst consensus Narrative on Simply Wall St frames the key question as how quickly that platform turns into contracted projects and meaningful revenue.

"NuScale Power's involvement in the RoPower 6 module SMR project in Romania remains a live driver, since progression beyond front end engineering still depends on project financing and further government approvals."

What happens to NuScale Power’s long run earnings power depends heavily on how one unresolved contracting and cost competitiveness debate is settled.

If that contracting question is what you are wrestling with, the full narrative for NuScale Power explains how NuScale Power’s pipeline, partners and funding path could either accelerate or stall.
