perform, and the acceptance criteria that are necessary and sufficient to provide reasonable assurance that, if the inspections, tests, and analyses are performed and the acceptance criteria met, the facility has been constructed and will operate in conformity with the COL, the provisions of the AEA, and the NRC's regulations. SRP Acceptance Criteria Branch technical positions (BTPs) and RGs that provide information, recommendations, and guidance and in general describe a basis acceptable to the staff that may be used to implement the requirements of GDCs 2, 4, 5, 17, 18, and 50 are identified in SRP Section 8.1, Table 8.1. 8.3.2-8 Revision 4 - May 2010 Specific SRP acceptance criteria acceptable to meet the relevant requirements of the NRC=s regulations identified above are as follows for the review described in this SRP section. The SRP is not a substitute for the NRC=s regulations, and compliance with it is not required. However, an applicant is required to identify differences between the design features, analytical techniques, and procedural measures proposed for its facility and the SRP acceptance criteria and evaluate how the proposed alternatives to the SRP acceptance criteria provide acceptable methods of compliance with the NRC regulations. 1. RG 1.6 Positions D.1, D.3, and D.4, as they relate to the independence between redundant onsite dc power sources and between their distribution systems. 2. RG 1.32, as it relates to the design, operation, and testing of the safety-related portions of the onsite dc power system. Except for sharing of safety-related dc power systems in multi-unit nuclear power plants, RG 1.32 endorses IEEE Std. 308-2001. 3. RG 1.75, as it relates to the physical independence of the circuits and electrical equipment that comprise or are associated with the onsite dc power system. 4. RG 1.81, as it relates to the sharing of SSCs of the dc power system. Regulatory Position C.1 states that multi-unit sites should not share dc systems. 5.
