Equipment Qualification

QualTech NP, a product and service brand of Curtiss-Wright Nuclear, performs environmental and seismic qualification for equipment used in nuclear safety-related applications. QualTech NP maintains an extensive library of qualification test procedures that can easily be adapted to any customer need, including new build construction requirements.

Curtiss-Wright Nuclear analyzes, tests, and qualifies materials and components under its Quality Assurance Program, which adheres to 10CFR50/Appendix B and ASME NQA-1.

Software analysis includes ALGOR and ANSYS finite element analysis. All physical and software testing is based on common standards, including:

  • IBC/UBC Commercial Seismic Code
  • International Building Code 2009
  • California Building Code 2007
    • AC156 (seismic) - “Acceptance criteria for Seismic Qualification Testing of Nonstandard components”
    • ASCDE 7-05 (seismic) - “Minimum design loads for building and other standards”
  • IEEE344
  • IEEE382
  • ASME Division 1 Section III Design Code
  • AISC Structural Steel Design Code

Please visit the Commercial Grade Dedication section for additional test services.

    Environmental Qualification

    Curtiss-Wright Nuclear provides complete environmental qualification engineering and testing for equipment in both harsh and mild environmental service conditions. Qualification programs are conducted by analysis, test, or a combination of both. Methodology depends on the equipment and its safety function, environmental service conditions, and other contributing factors. Curtiss-Wright Nuclear can also provide support for EMI/RFI testing and Software Validation and Verification.
