of the equipment. Meeting GDC 23 provides assurance that the failure mode of protection system components is considered in the environmental design and qualification process. 3.11 -19 Draft Revision 4 – December 2017 7. Compliance with 10 CFR Part 50, Appendix B, Criterion III, “Design Control,” requires that measures be established to ensure that applicable regulatory requirements and the associated design bases are correctly translated into specifications, drawings, procedures, and instructions. These measures shall include provisions to ensure that appropriate quality standards are included in design documents and that deviations from established standards are controlled. A process shall also be established to determine the suitability of equipment that is essential to safety-related functions and to identify, control, and coordinate design interfaces between participating design organizations. Where a test program is used to verify the adequacy of a specific design feature, it shall include suitable qualification testing of a prototype unit under the most adverse design conditions. 10 CFR 50, Appendix B, Criterion III is applicable to this Section since it includes requirements for test programs that are used to verify the adequacy of a specific design feature. Such test programs must include suitable qualification testing of a prototype unit under the most adverse design conditions. For components in the scope of this section that are subject to environmental qualification testing, the test program must address these requirements. Meeting 10 CFR Part 50, Appendix B, Criterion III provides assurance that the environmental qualification process includes suitable qualification testing of a prototype unit under the most adverse design conditions. 8. Compliance with 10 CFR Part 50, Appendix B, Criterion XI, “Test Control,” requires that a test control plan be established to ensure that all tests needed to demonstrate a component's capability to perform
