t the staff has found to be acceptable, with clarifications, as documented in the NRC safety evaluation report, “Safety Evaluation by the Office of Nuclear Reactor Regulation Electric Power Research Institute Topical Report, TR 106439, Guideline on Evaluation and Acceptance of Commercial Grade Digital Equipment for Nuclear Safety Applications,” dated July 17, 1997 (Ref. 18). 4. Annex D, “Identification and Control of Hazards,” provides guidance for identifying and controlling hazards. Section C of this RG discusses the NRC’s endorsement of Annex D. 5. Annex E, “Communication Independence,” has not received NRC endorsement. This RG endorses, with clarifications, the communication independence criteria within the normative parts of the standard, as discussed in Section C of this RG. DG-1374, Page 6 6. Annex F, “Computer Reliability,” has been deleted. 7. Annex G, “Glossary,” defines certain terms used in the standard. This annex does not contain any guidance or requirements. 8. Annex H, “Bibliography,” contains the references used in the standard. This annex does not contain any guidance or requirements. Consideration of International Standards The International Atomic Energy Agency (IAEA) works with member states and other partners to promote the safe, secure, and peaceful use of nuclear technologies. The IAEA develops Safety Requirements and Safety Guides for protecting people and the environment from the harmful effects of ionizing radiation. This system of safety fundamentals, safety requirements, safety guides, and other relevant reports, reflects an international perspective on what constitutes a high level of safety. To inform its development of this RG, the NRC considered IAEA Safety Requirements and Safety Guides pursuant to the Commission’s International Policy Statement (Ref. 19) and Management Directive and Handbook 6.6, “Regulatory Guides” (Ref. 20). No relevant international standards related to promoting high functional
