methods of compliance with the NRC regulations. 1. SRP Appendix 7.1-B provides guidance for evaluating conformance to the requirements of IEEE Std 279-1971. 2. SRP Appendix 7.1-C provides guidance for evaluating conformance to IEEE Std 603-1991. 3. SRP Appendix 7.1-D provides guidance for evaluating conformance to the acceptance criteria contained in RG 1.152, “Criteria for Use of Computers in Safety Systems of Nuclear Power Plants,” which endorses IEEE Std 7-4.3.2, “IEEE Standard Criteria for Digital Computers in Safety Systems of Nuclear Power Generating Stations.” III. REVIEW PROCEDURES The reviewer will select material from the procedures described below, as may be appropriate for a particular case. Typical reasons for a non-uniform placement of emphasis are the introduction of new design features or the use in the design of features previously reviewed and found acceptable. These review procedures are based on the identified SRP acceptance criteria. For deviations from these acceptance criteria, the staff should review the applicant’s evaluation of how the proposed alternatives provide an acceptable method of complying with the relevant NRC requirements identified in Subsection II. SRP Section 7.1 describes the general procedures to be followed in reviewing any I&C system. Therefore, review procedures specific to any DCS can be synthesized from SRP 7.9-6 Draft Revision 6 - August 2015 Appendix 7.1-A. NUREG/CR-6082, “Data Communications,” discusses data communication technology and the technical rationale for review issues specific to data communications and includes background information to assist the reviewer in identifying critical technical features. This part of SRP Section 7.9 highlights specific topics that should be emphasized in the DCS review. The review should include an evaluation of the DCS against the guidance of IEEE Std 603-1991 or IEEE Std 279-1971, depending on the applicant’s or licensee’s commitment regarding these design
