X-energy (XE), the developer of the Xe-100 advanced small modular reactor (SMR) and XENITH microreactor, made its public market debut earlier this month. The company executed an upsized initial public offering that raised more than $1 billion. While the listing underscores strong investor enthusiasm for next-generation nuclear technology, the company remains pre-revenue. It carries the typical execution risks associated with bringing a new reactor design to commercialization.
Investors seeking participation in X-energy’s growth story without bearing the full equity risk of its stock can instead gain diversified exposure through the established suppliers and service providers positioned to support its reactor deployments. The VettaFi Nuclear Renaissance Index (NUKZX) includes several of these key partners, offering a lower-risk way to capture upside from the company’s major projects with Amazon, Dow, and others. NUKZX is the underlying index for the Range Nuclear Renaissance Index ETF (NUKZ ).

X-energy’s Xe-100 represents a Generation IV high-temperature gas-cooled reactor (HTGR) design that promises enhanced safety, modularity, and suitability for industrial applications and data-center power. The company’s commercial pipeline now exceeds 11 gigawatts (GW), anchored by a strategic partnership with Amazon to deploy more than 5 GW of Xe-100 capacity across the United States by 2039, as well as the first four-unit plant at Dow’s Seadrift, Texas, manufacturing site. These projects highlight the demand for reliable, carbon-free power and create immediate contracting opportunities across the nuclear value chain.
Supply Chain Partners
Several NUKZX constituents are already embedded in X-energy’s deployment plans, delivering engineering, manufacturing, instrumentation, and construction services that reduce overall project risk while generating revenue for these established public companies:
- Korea Hydro & Nuclear Power (KHNP), owned by KEPCO (015760.KS), forms part of the strategic collaboration with X-energy, Amazon, and Doosan Enerbility to scale Xe-100 deployment in the United States. The partnership leverages KHNP’s extensive reactor expertise and supports the multi-gigawatt pipeline targeting data-center and industrial power needs.
- Doosan Enerbility, owned by Doosan Corp (000150.KS), has executed a binding reservation agreement to manufacture core steel components for an initial 16 Xe-100 units and is expanding manufacturing capacity to support X-energy’s full 11 GW pipeline. The company’s heavy industrial capabilities position it to deliver critical long-lead equipment on an accelerated timeline.
- Curtiss-Wright (CW) signed a preferred strategic supplier agreement with X-energy to provide nuclear steam supply system components, including helium circulators, fuel handling systems, and reactivity control mechanisms.
- Mirion Technologies (MIR) strengthened its SMR market positioning through the acquisition of Paragon Energy Solutions, a leading provider of highly engineered nuclear solutions. Paragon will supply reactor protection systems, neutron instrumentation, and post-event monitoring equipment tailored for large-scale plants and advanced reactors, including the Xe-100.
- Fluor (FLR) recently secured a contract to provide engineering, project management, and risk mitigation services for the four-unit Xe-100 plant at Dow’s Seadrift site. Fluor’s deep experience in nuclear engineering, procurement, and construction makes it a leading partner for delivering complex projects on schedule and on budget.
These partnerships illustrate how X-energy’s momentum directly benefits a broad set of established firms. This may be more appealing than trying to play a single stock. Licensing progress, customer commitments, and supply chain agreements will potentially translate into tangible orders and revenue streams for NUKZX constituents.
The developments underscore the broader advantages of investing through the nuclear value chain. While X-energy’s IPO highlights the excitement around advanced reactors, the real near-term value creation often accrues to the equipment manufacturers, service providers, and engineering firms that turn designs into operating power plants.
NUKZX includes companies across the nuclear value chain, from fuel to utilities. For investors interested in the global growth opportunity for nuclear power, NUKZX offers a diversified group of companies positioned to benefit from the full spectrum of the nuclear renaissance.
