SUBJECT:
REVIEW 0F EPRI TOPICAL REPORT TR-106439, " GUIDELINE ON EVALUATION AND ACCEPTANCE OF COMMERCIAL GRADE DIGITAL EQUIPMENT FOR NUCLEAR SAFETY APPLICATIONS" (TAC NO. M94127) l
Dear Mr. Torok:
By letter dated December 4,1996, the Electric Power Research Institute (EPRI) submitted topical report TR-106439, " Guideline on Evaluation and Acceptance of j Commercial Grade Digital Equipment for Nuclear Safety Applications," for staff
' review. The staff has completed its review of EPRI's topical report and prepared the enclosed safety evaluation report.
The staff has determined that TR-106439 contains an acceptable method for
' dedicating commercial grade digital equipment for use in nuclear power plant safety applications and meets the requirements of 10 CFR Part 21. Further, the staff concludes that when digital equipment is dedicated using the methods described in TR-106439, it may be considered equivalent to digital equipment designed and manufactured under a 10 CFR Part 50, Appendix B quality assurance j program. Licensees may utilize the TR-106439 approach when installing digital l modifications utilizing commercial grade equipment. This includes microprocessors that are embedded in electrical and mechanical equipment as
.j well as process instrumentation and control systems. While the staff finds 1
-TR-106439 acceptable, it is a generic proposal and therefore, licensees j referencing TR-106439 will need to document the details regarding the dedication process and specific critical characteristics including the
] verification information described in Standard Review Plan Chapter 7 such as
- qualification reports, system description and software and hardware design and t
quality assurance documentation. The staff will include a reference to TR-106439 in Chapter 7 of the Standard Review Plan.
