From critical reactor components to balance of plant systems, we test the full spectrum of nuclear facility materials and components. We provide qualified replacements from over 200 manufacturers including Bussman, Siemens, Yokogawa, and GE, with technical evaluations, critical characteristics verification, and safety class determinations for each product. We specialize in testing, inspection and analysis of materials used in all stages of nuclear power generation, from new construction to ongoing operations and decommissioning projects. 

• Safety Relief Valves and Snubbers
• Digital assets for control room and plant use
• Metallic and non-metallic component materials
• Harsh and mild environment equipment
• Welded and machined parts

Our solutions span the complete nuclear facility lifecycle, from new build quality assurance to life extension assessments and decommissioning support. We conduct Fitness For Service (FFS) testing and Engineering Critical Assessment (ECA) to maintain structural integrity while minimizing risks. For decommissioning, we provide materials testing, integrity verification, and environmental compliance, including asbestos remediation and air quality monitoring. Our comprehensive approach helps you minimize operational risks, prevent production losses, and avoid severe environmental impacts throughout your facility's lifecycle.

• New build quality assurance from design to commissioning
• Fitness For Service (FFS) assessments for operational assets
• Engineering Critical Assessment (ECA) for structural integrity
• Life extension evaluations for aging facilities
• Decommissioning support with environmental compliance
• Asbestos remediation works during site decommissioning
• Management surveys and project management

Regulatory and environmental compliance
Our environmental experts in the UK provide crucial support for your regulatory compliance needs, including workplace air monitoring, electromagnetic field surveys, asbestos testing, and occupational hygiene services. All operations align with national legislation like CAR 2012 and international standards ISO/IEC 17025 and ISO/IEC 17020, helping you maintain environmental safety throughout facility operation and decommissioning. We help you navigate complex regulatory frameworks while ensuring your facility maintains the highest levels of environmental protection and worker safety.

• Workplace air quality monitoring and assessment
• Electromagnetic field surveys and radiation protection
• Comprehensive asbestos management services
• Asbestos air testing and removal project management
• Occupational hygiene evaluations
• Environmental compliance auditing
• Refurbishment and demolition environmental surveys
• Regulatory documentation and reporting support

Our Digital Engineering team utilizes advanced modeling and simulation software to calculate safety and efficiency of critical components during design and development. We apply thermal hydraulics simulation for primary, secondary, and tertiary circuits, while our integrity specialists leverage nuclear integrity codes including R5, R6, and ASME design standards to deliver comprehensive component assessments. These digital capabilities allow us to identify potential issues early in the development process, reducing costs and enhancing safety before physical components are manufactured or installed. For physical testing, we utilize three single axis, triaxial and biaxial seismic machines for quick response to your needs.

• Advanced modeling and simulation software
• Thermal hydraulics simulation technologies
• Non-destructive testing equipment for in-service inspection
• Specialized tools for mechanical and fracture toughness testing
• Corrosion testing apparatus
• Coatings performance assessment equipment
• Air monitoring and environmental testing instrumentation
• Seismic qualification testing systems
• More than 30 different aging ovens for environmental qualification with temperatures continuously recorded and maintained within +5/-0°F using redundant controllers to prevent overheating
• Eight permanent test chambers using saturated and superheated steam, water and chemical spray availability for LOCA and submergence testing

Our Huntsville, AL Nuclear Center of Excellence lab is IEEE ICAP certified and radioactive material licensed with a compliant NUPIC and NIAC audited Nuclear QA program. In the UK, we are part of the Equipment Qualification Services Alliance (EQSA), helping UK manufacturers trade in the nuclear industry. As members and direct participants in industry task groups, Element maintains a clear edge by actively developing standards, guidelines and resolution of key NRC questions about critical characteristics verification, sampling, traceability, surveys, and like-for-like replacements.
