Nuclear Engineering Services

Tetra Engineering, brings decades of expertise to the demanding world of nuclear engineering. This has given us a profound understanding of the unique regulatory, safety, and technical challenges involved in the operation and design of nuclear power plants.

Our Nuclear Heritage

Tetra Engineering was founded by former employees of Combustion Engineering’s nuclear division.  In our early years, the company was therefore focused primarily on nuclear engineering and technology. As the power industry generation mix shifted, we broadened our services to conventional thermal power generation. Today, with the renewed interest in nuclear energy, we are leveraging that foundation to deliver specialized technical support in key areas:

  • Reactor Physics – Expertise in fuel physics computer codes (in particular legacy Combustion Engineering codes) as well as reactor I&C.
  • Steam Generators – Analysis and Assessment of these critical heat-exchange components.
  • Radiation Damage to Materials – Assessment of material integrity under irradiation.
  • Radiation Transport Simulations – Advanced modeling for shielding and dose evaluation.

The combination of historical engineering knowledge, combined with our modern engineering tools capabilities, positions Tetra as a trusted consulting partner for nuclear operators worldwide.

Nuclear Engineering Service Offering

Inspection Support

  • Assisting in the development of inspection plans for visual and non-destructive (NDT) condition-monitoring inspections of key nuclear plant components: pressure vessels, steam generators, piping networks, heat exchangers, among others.
  • Auditing inspection plans against regulatory schedules.
  • Evaluation of inspection reports

Remaining Life and Life-Extension Assessments

  • Life and Fitness-for-service assessments (creep, fatigue, vessel embrittlement).
  • Finite Element Analysis (FEA) of reactor and other balance-of-plant components
  • MCNP code simulation for shielding and material damage projections

Third-Party Engineering Audits and Assessments

  • Vendor scope review, checklist generation, audit execution.
  • Independent reporting and expert-witness support.
  • Assurance reviews of subcontractor inspection results.

Industries & Asset Types We Serve

  • Nuclear Power Generating Stations – Steam generators, pressure vessels, piping, heat exchangers.
  • Research Reactors and Irradiation Facilities
  • Nuclear-adjacent thermal and process systems (supporting plant, waste heat, combined-cycle systems).

Why Choose Tetra Engineering for Support

With decades of experience in providing engineering analysis and plant field inspection work for nuclear and conventional power plants, Tetra Engineering brings a proven, cross-industry perspective to any power generation project. Our team understands the unique requirements of nuclear operations and we aim to deliver consulting services that satisfy the most demanding client timelines, safety protocols, and performance expectations.

What sets us apart?

  • Specialised Expertise – Our engineers have hands-on experience with steam-generation plants, HRSGs, pressure parts, and power piping systems skills that translate directly into the nuclear environment.
  • Compliance-Driven Approach – Every inspection aligns with nuclear regulatory frameworks and international standards (ASME, EN, ISO), reinforcing safety culture at every step.
  • Integrated Solutions – From inspection planning to life-integrity assessments and fitness-for-service analysis to root-cause diagnostics and independent reviews, we deliver actionable insights, not just findings.
  • Tailored Strategies – Whether your plant is in early operation, mid-life, or preparing for decommissioning, we adapt our inspection plans to your asset condition, risk profile, and regulatory context.
