International Nuclear Solutions

What International Nuclear Solutions does

International Nuclear Solutions, LLC (INS) is a privately held Texas LLC headquartered in The Woodlands, Texas, that provides specialized goods and services to the nuclear power generation industry across North America. The company's offerings span two complementary revenue streams. First, a professional services portfolio that includes staff augmentation of certified nuclear technicians (with sourcing from both domestic and international talent pools), radioactive waste management, surface decontamination (CO2 blasting, hydrolasing, sponge blasting, source term reduction, pressure washing), laboratory and instrumentation services, non-destructive testing, and engineering staffing for mission-critical data center construction projects. Second, a hardware and consumables products portfolio comprising ALARA-compliant tool design and manufacturing, video and audio monitoring equipment, specialized instrumentation and software, remote monitoring technologies, personal protective equipment (PPE), decontamination resins for liquid processing, and custom specialized tools and parts.

INS goes to market through an enterprise field sales motion targeting nuclear power plants, government agencies, and private sector partners, with named engagements at facilities operated by Constellation Energy (LaSalle, Dresden, Peach Bottom, Limerick), Vistra Energy (Perry, Beaver Valley, Comanche Peak), DTE Energy (Enrico Fermi), Florida Power & Light (Turkey Point, St. Lucie), Entergy (River Bend), STP, and the Three Mile Island decommissioning project. The company operates from a U.S. headquarters in The Woodlands, TX plus two offices in Mexico (Mexico City and Veracruz), suggesting a North American, bilingual service delivery model.

The company positions itself on regulatory compliance expertise, access to certified technicians, and breadth across both services and products. No public revenue, headcount, founding date, or external funding is disclosed. Growth signals include active hiring of Radiation Protection Technicians, the launch of a Mission Critical Workforce line targeting U.S. data center construction, and Mexico footprint expansion.

Direct peers

• NAC International: NAC International offers nuclear fuel cycle, decommissioning, and engineering services to utilities and government clients. Its mix of consulting, technical services, and specialized nuclear products parallels INS's service-plus-product positioning.
• EnergySolutions: EnergySolutions is the largest US provider of nuclear decommissioning, waste management, and operational services. INS engages as a subcontractor to EnergySolutions on Three Mile Island, making them the most directly comparable peer in service scope and customer base.
• Studsvik: Studsvik provides specialized nuclear services including decontamination, decommissioning, waste treatment, and fuel services globally. Its service portfolio and customer base (nuclear utilities and government agencies) closely mirror INS's operational services stack.
• Veolia Nuclear Solutions: Veolia Nuclear Solutions (formerly Kurion) specializes in radiological waste treatment, decontamination, and decommissioning technology for nuclear sites. It competes head-to-head with INS in decontamination and waste management services.
• Holtec International: Holtec is a vertically integrated nuclear technology and decommissioning company that designs equipment and provides D&D, waste management, and operational services to US nuclear plants — directly overlapping INS's decontamination, waste management, and specialized tooling offerings.
• Enercon Services: Enercon provides environmental, engineering, and nuclear licensing/services to the US power industry, including radiation protection and operational support to nuclear utilities — a closely comparable specialized services peer in the same target segment.

Broad incumbents

• AtkinsRéalis (SNC-Lavalin Nuclear): AtkinsRéalis operates a major nuclear engineering and services practice serving utilities and governments worldwide with CANDU reactor services, decommissioning, and waste management — a larger incumbent covering much of INS's service space with broader geographic reach.
• Westinghouse Electric Company: Westinghouse is a leading global nuclear plant designer and provides fuel, services, and decommissioning to the operating fleet. As a broad incumbent, it competes with INS in plant services, instrumentation, and decommissioning support, though at much greater scale.
• Tetra Tech: Tetra Tech provides consulting and engineering services to US nuclear utilities including environmental compliance, decommissioning, and waste management. It is a broader environmental/engineering incumbent with overlapping nuclear services capabilities.
• Curtiss-Wright (Nuclear Division): Curtiss-Wright supplies nuclear-qualified instrumentation, controls, and specialty equipment, and provides reactor services. It overlaps with INS's instrumentation products and plant services, though as part of a much broader defense/aerospace portfolio.
