U.S. NUCLEAR REGULATORY COMMISSION Revision 2 November 1978 REGULATORY GUIDE OFFICE OF 'STANDARDS DEVELOPMENT REGULATORY GUIDE 1.72 SPRAY POND PIPING MADE FROM FIBERGLASS-REINFORCED THERMOSETTING RESIN A. INTRODUCTION General Design Criterion 1, "Quality Stand ards and Records," of Appendix A, "General Design Criteria for Nuclear Power Plants," to 10 CFR Part 50, "Domestic Licensing of Pro "-duction and Utilization Facilities," requires that structures, systems, ý and .components important ..to safety be designed, fabricated, erected, and tested to quality standards com mensurate with the importance of the safety functions to be performed. Appendix B, "Qual ity Assurance Criteria for Nuclear Power Plants and Fuel Reprocessing Plants," to 10 CFR Part 50 requires that measures be established to ensure materials control and control of special processes such as resin molding. Section 50.55a, "Codes and Standards," of 10 CFR Part 50 requires that design, fabrica tion, installation, testing, or inspection of the specified system or component be in accordance with generally recognized codes and staridards. Footnote 6 to § 50.55a states that the use of specific Code Cases may be authorized by the Commission upon request pursuant to § 50.55a (a)(2)(ii), which requires that proposed alter natives to the described requirements or por tions thereof provide an acceptable, level of quality and safety. This guide describes a method acceptable to the NRC staff for implementing these require ments with regard to the design, fabrication, and testing of fiberglass-reinforced thermo setting resin (RTR) piping for spray pond applications. This guide applies to light-water cooled and gas-cooled reactors. .The Advisory Committee on Reactor Safeguards has been con sulted concerning this guide and has concurred in the regulatory position. *Lines indicate substantive changes tram previous issue.
