Core offering

Orion Nuclear Energy Corporation develops, finances, builds, and operates Small Modular Reactor (SMR) and Micro-Modular Reactor (MMR) nuclear power projects. The company partners with established nuclear technology firms to deploy factory-built modular reactors and sells the generated electricity directly to large, high-power-intensity enterprise offtakers such as data centers, military bases, university systems, and large industrial facilities under long-term fixed contracts.

Product overview

Orion Nuclear Energy Corporation is a nuclear power project developer specializing in the deployment of Small Modular Reactors (SMRs) and Micro-Modular Reactors (MMRs). The company offers a unified service offering that encompasses project development, financing, land acquisition, construction, and electricity sales. SMRs and MMRs serve as the core nuclear power products, with development services integrating these technologies for deployment at data centers, military bases, university systems, and large industrial facilities.

Partnerships

One partnership is on record.

• ConstelliscoreStrategic or Co-development Partner · 18 February 2026Orion Nuclear Energy Corporation and Constellis signed a Memorandum of Understanding (MoU) to collaborate on integrating security by design into advanced nuclear energy projects and critical infrastructure. The collaboration explores deploying Constellis' LEXSO™ (Layered Extended Security Operations) platform across Orion Nuclear's portfolio of commercial-scale advanced nuclear power projects. The effort aims to embed modern security architectures from project inception through operations, including lifecycle security by design, real-time situational awareness, joint security risk assessments, and pilot deployments.

Recent moves5 records

Expansion highlights6 records

Regional players

• Rolls-Royce SMR: UK-based SMR developer pursuing domestic and select international deployments; comparable SMR offering but primarily competing in UK/European markets rather than directly in Orion's U.S. footprint.

Direct peers

• X-energy: Develops the Xe-100 high-temperature gas microreactor and TRISO-X fuel; competing directly with Orion for data center and industrial customers and backed by Amazon and Dow partnerships.
• Last Energy: Small modular reactor developer focused on private, behind-the-meter power for industrial and data center customers in Europe and the U.S.; competing for the same offtaker segment.
• Oklo: Microreactor developer (Aurora powerhouse) pursuing behind-the-meter power for data centers, military, and industrial sites — overlapping directly with Orion's target customer set.
• NuScale Power: U.S.-based SMR developer with the only NRC-approved SMR design; competes with Orion for the same data center, utility, and industrial offtakers and is further along in licensing and commercialization.
• TerraPower: Bill Gates-backed advanced reactor developer building a Natrium sodium-cooled fast reactor demonstration and targeting similar industrial and utility customers; significant DOE and private capital.

Others

• Centrus Energy: U.S. supplier of enriched uranium for civilian nuclear power; an upstream fuel-chain participant relevant to Orion's LEU-fueled SMR/MMR deployments.

Emerging players

• Holtec International: Nuclear services and SMR-160 reactor developer; an emerging player targeting industrial and data center power with a smaller modular reactor design.

Broad incumbents

• BWX Technologies: Major nuclear components and fuel manufacturer developing microreactors (e.g., BANR) and supplying the broader advanced reactor ecosystem in which Orion operates.
• Westinghouse Electric Company: Established nuclear OEM with AP1000 and eVinci microreactor programs; broader portfolio but directly relevant as a competitor and potential technology partner for Orion's deployments.
