significant components than for high safety- significant components. In making these changes, licensees must consider requirements in 10 CFR Part 21 and Appendix B to 10 CFR Part 50 and must consider any still-current commitments based on the 1.176-15 use of withdrawn regulatory guides..2 Within this area, the technical requirements for commercial grade item (CGI) dedication in accordance with 10 CFR Part 21 (critical characteristics of an item for an application) are not subject to grading. However, for safety-related items of low safety significance, the verification of critical characteristics may be graded (e.g, by reduced sampling plans or alternative testing techniques). Other procurement-related activities such as auditing, qualifying suppliers, and receipt inspection may also be graded. Licensees should consider the role its procurement practices play in ensuring the prevention of cross-system common cause failures and implement the procurement activities accordingly. A licensee may choose to reduce current commitments regarding certificates of conformance that are based upon regulatory guides that have been withdrawn..2 The licensee would instead follow the guidance in sections 4.2.a, I 0.2.a through f, and 10.3.2 in ANSI N45.2.13 (Ref. 6). A licensee may choose to reduce commitments to ANSI N45.2. 13 (Ref. 6) regarding source verifications and procurement program audits described in Sections 7.2.1,7.3.1, 10.3.1, and 12. The change of practices in this area for low safety-significant items would be appropriate. However, licensee practices for receipt inspections, post-installation testing, and a compo- nent-level monitoring program will provide feedback to identify any necessary corrective actions. A licensee may reduce commitments associated with Regulatory Guide 1.38 (Ref. 7) and other (previously withdrawn) guides2 and with ANSI N45.2.12 and N45.2.2 (Refs. 8 and 9) regarding the conduct of external supplier audits and supplier evaluations.
