nected to Low-Voltage (1000 V and Less) AC Power Circuits” (w) RG 1.209, “Guidelines for Environmental Qualification of Safety Related Computer-Based Instrumentation and Control Systems in Nuclear Power Plants.” Applicability - All I&C safety systems and supporting data communications systems. Review Methods - RG 1.209 provides a basis for evaluating conformance of computers with GDC 4. RG 1.209 provides environmental qualification practices that contribute to ensuring that computers can perform their safety-related functions under all anticipated service conditions. RG 1.209 provides environmental qualification procedures for computers located in a mild environment and compliments RG 1.89, Revision 1, “Environmental Qualification of Certain Electric Equipment Important to Safety for Nuclear Power Plants,” which addresses environmental qualification for harsh environments. SRP Appendix 7.1-D provides review guidance for the evaluation of environmental qualification of computers. 5. SRP Branch Technical Positions Applicability - As noted in SRP Table 7-1. Appendix 7.1-A-37 Draft Revision 6 – August 2015 Review Methods - The SRP BTPs provide bases for evaluating specific review areas. REFERENCES 1.
