"uj October 1973 U.S. ATOMIC ENERGY COMMISSION REGULATORY DIRECTORATE OF REGULATORY STANDARDS GUIDE REGULATORY GUIDE 1.66 NONDESTRUCTIVE EXAMINATION OF TUBULAR PRODUCTS A. INTRObUCTION General Design Criterion 1, "Quality Standards and Records," of Appendix A, "General Design Criteria for Nuclear Power Plants," to 10 CFR Part 50, requires that structures, systems, and components important to safety he designed, fabricated, erected, and tested to quality standards commensurate with the importance of the safety functions to be performed. Appendix B, "Quality Assurance Criteria for Nuclear Power Plants and Fuel Reprocessing Plants," to 10 CFR Part 50, requires that nIeasures he established to assure materials control and control of special process, and that proper testing be performed. This guide describes a method of implementing these requirements acceptable to the AEC Regulatory staff with regard to the nondestructive examination requirements for tubular products used for 'mponents of the reactor coolant pressure boundary A other -safety-related systems. This guide applies to light-water-cooled reactors. The Advisory Committee on Reactor Safeguards has been consulted concerning this guide and has concurred in the regulatory postion. B. DISCUSSION The requirements for nondestructive examination of wrought seamless tubular products used for components of nuclear power plants are specified in paragraph NB-2550 of Section 111, "Nuclear Power Plant Components," American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code.' These code requirements cover the examination of several product forms (pipe, tubing, flar~ges, fittings) under a single category, "Seamless and Welded (Without Filler Metal) Tubular Products and Fittings"' without specifying the examination method to be used for each 'Copies may be obtained from the American Society of Mechanical Engineers, United Engineering Center, 345 East 47th Street, New York, New York 10017. product form.
