that “TR-106439 contains an acceptable method for dedicating commercial grade digital equipment for use in nuclear power plant safety applications.” If the guidance in EPRI TR-106439 is applied in the dedication of a component, the following items should be noted by the reviewer: • TR-106439 is not intended to be used as a detailed “how-to” manual. There may be significant variation in specific steps taken depending on vendors, components, and applications. Detailed specific information, in addition to that provided in the report examples, will be needed to perform an actual commercial dedication. Use of TR-106439 in connection with a license amendment or 10 CFR 50.59 evaluation should include descriptions of alternatives selected and deviations from the guidance in the documentation of the acceptance process. • The dedication effort can be “graded” based on safety significance and relative complexity. • TR-106439 references EPRI NP-5652, which discusses four methods for use in commercial dedication:(1) special tests and inspections, (2) commercial-grade survey of supplier, (3) source verification, and (4) acceptable supplier/item performance record. As noted in TR-106439, supported by Generic Letters 89-02, "Actions to Improve the Detection of Counterfeit and Fraudulently Marketed Products," and 91-05, "Licensee Commercial-Grade Procurement and Dedication Programs," for typical applications no one method will suffice by itself, and it is likely that methods 1, 2, and 4 will all be needed. Rev. 4 — June 1997 SRP 7.0-A-14 • The examples listed in TR-106439 are not all-inclusive. Depending on application and product specifics, some of the evaluations may not be needed or additional verification activities, beyond those listed in the example, might be necessary. • Engineering judgement applied in the acceptance process must be documented sufficiently to allow a comparably qualified individual to reach the same conclusion. • The validity of the
