ptions of the alternatives selected and deviations from the guidance in the documentation of the acceptance process. • The dedication effort may be "graded" based on safety significance and relative complexity. • EPRI 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 EPRI TR-106439, supported by Generic Letters 89-02, "Actions to Improve the Detection of Counterfeit and Fraudulently Marketed Products," and 91-05, "Licensee Appendix 7.0-A-16 Revision 5 - March 2007 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. • The examples listed in EPRI 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 commercial-grade item dedication must be maintained as long as the item remains in service. Dedicated software items should not be updated to new revision levels without prior evaluation to determine if a design change is required. Commercially dedicated items should not be operated in a configuration outside the bounds of the original dedication. • The utility should arrange to be notified by the vendor when defects are discovered. This requires confirmation that the vendor's processes will support this need. • EPRI TR-106439 notes that not all commercial items can be successfully dedicated. D. REFERENCES 1. ASME Std.
