C.2 concerning performance of design verification by supervisors. *Lines denote substantive changes from previous issue. C. REGULATORY POSITION The requirements and recommendations for establish- ing and executing a quality assurance program during the design phase of nuclear power plants that are included in ANSI N45,2.11-1974* are acceptable to the NRC staff and provide an adequate basis for complying with the pertinent quality assurance requirements of Appendix B to 10 CFR Part 50, subject to the following: 1. Subdivision 1.5 of ANSI N45.2.11-1974 states that other documents that are required to be included as a part of this standard will be identified at the point of reference and described in Section 12 of the standard. The specific acceptability of these listed documents has been or will be covered separately in other regulatory guides or in Commission regulations where appropriate. 2. Instead of the second sentence of the second paragraph of Section 6.1 on design verification, the following should be used: "The duties of a 'supervisor' and the relationship with subordinates vary widely in dif- ferent organizations. Regardless of their title, individulds performing design verification should not (1) have immediate supervisory responsibility for the individual performing the design, (2) have specified a singular design approach, (3) have ruled out certain design considerations, or (4) have established the design inputs for the particular design aspect being verified. While design verification by the designer's immediate supervi- sor is encouraged, it should not be construed that such verification constitutes the required independent design *ANSI N45.2.11-1974, "Quality Assurance Requirements for the Design of Nuclear Power Plants," may be obtained from the American Society of Mechanical Engineers, United Engineering Center, 345 East 47th Street, New York, NY 10017.
