latory positions described in Section C of this guide, American National Standards Institute/International Society of Automation (ANSI/ISA) -67.02.01-2014, “Nuclear Safety-Related Instrument Sensing Line Piping and Tubing Standard for Use in Nuclear Power Plants” (Ref. 1). Applicability This RG applies to applicants for and holders of licenses as defined by Title 10 of the Code of Federal Regulations (10 CFR) Part 50, “Domestic Licensing of Production and Utilization Facilities” (Ref. 2), in 10 CFR 50.2, “Definitions,” excluding an early site permit. This RG also applies to applicants for, and holders of, a standard design approval issued under Subpart E, “Standard Design Approvals,” of 10 CFR Part 52, “Licenses, Certifications, and Approvals for Nuclear Power Plants” (Ref. 3) and applicants for a standard design certification issued under Subpart B, “Standard Design Certifications,” of 10 CFR Part 52. Applicable Regulations • 10 CFR 50.34, “Contents of applications; technical information” provides requirements for the content of the preliminary safety analysis report to be included in a construction application. Under the provisions of 10 CFR 50.34, an application for a construction permit must include the principal design criteria for a proposed facility. The principal design criteria establish the necessary design, fabrication, construction, testing, and performance requirements for structures, systems, and components important to safety; that is, structures, systems, and components that provide reasonable assurance that the facility can be operated without undue risk to the health and safety of the public. DG-1352, Page 2 • 10 CFR 52.47, 52.79, 52.137, and 52.157 also require that an application for a design certification, combined license, design approval, or manufacturing license, respectively, must include the principal design criteria for a proposed facility. • The General Design Criteria (GDC) in Appendix A to 10 CFR Part
