EPC Nuclear & Industrial Engineering

Trusted Expertise in NQA‑1 Quality Assurance & Commercial Grade Dedication

Delivering Excellence from Start to Finish

Our company delivers full-service Engineering, Procurement, and Construction (EPC) solutions built on the rigorous foundations of ASME NQA‑1 and 10 CFR 50 Appendix B standards, ensuring seamless integration of engineered components, procurement controls, and construction activities into nuclear and safety-critical projects.

Services we offer

N/A

We maintain a QA infrastructure compliant with ASME NQA‑1 (2008/09 up to 2024), 10 CFR 50 Appendix B, 10 CFR 21, and DOE 414.1D. Our program supports certification (e.g. ASME NQA‑1 Certification Program) and is ready for audit by industry authorities such as NUPIC.

From front-end engineering design through procurement and construction, our team ensures early contractor involvement, optimizes constructability, and maintains transparent scheduling and cost-control across safety-critical assets.

Adhering to ASME NQA‑1 Subpart 2.14 and EPRI NP‑5652 guidelines, we transform commercial-grade items into safety-qualified components via a robust CGD process:

  1. Technical evaluation by engineers to define safety functions.
  2. Identification of Critical Characteristics for Acceptance (CCFA).
  3. Tailored sampling & acceptance test plans (non-destructive, destructive, environmental).
  4. In‑house testing and verification.
  5. Documentation with full traceability and Certificate of Conformance.
