re selected. In addition, Step 5.2.2, “Is the Item Required to Comply with Codes and/or Standards?” of EPRI 3002002982 indicates that dedication is a process used to accept an item by establishing reasonable assurance that it will perform its safety function and is not intended for use as a basis for certifying a code or standard. EPRI 3002002982 specifies that if absolute assurance of compliance with all applicable requirements of a code or standard is required, and the item is not eligible for dedication, then the item should be procured as a basic component or otherwise controlled in accordance with a QA program compliant with 10 CFR Part 50, Appendix B. EPRI 3002002982, Section 5.14, “Screen for Eligibility Process: Steps 5.2.1–5.2.6,” states that one option to obtain information that will help determine whether an item can be dedicated is “reverse engineering” of the component. Operating experience has revealed challenges associated with the use of reverse engineering in determining significant design and performance attributes for replacement components in nuclear power plants. Reverse engineering is not within the scope of EPRI 3002002982. EPRI is preparing a separate guidance document for the use of reverse engineering to provide reasonable assurance of the capability of replacement components to perform their intended functions consistent with the design and performance of the original component. EPRI 3002002982 Section A "Design versus Acceptance states: “As discussed in GL 89-02, “Actions to Improve the Detection of Counterfeit and Fraudulently Marked Products,” appropriate engineering involvement is warranted during the procurement and product acceptance processes, including testing, for products used in nuclear power plants". To provide consistency when addressing NRC oversight activities, the NRC staff is clarifying the definition of counterfeit, fraudulent, and suspect items in the Staff Regulatory Guidance.
