ibed in Section C.III.1 of Regulatory Guide 1.206. Further detailed information and guidance on electrical design for passive COL applications are provided in Section C.III.1.8.3.1 of Regulatory Guide 1.206, SECY-94-084, and SECY-95-132. The COL applicant should submit a reliability assurance program describing the reliability assurance activities it will perform before the initial fuel load. This program should maintain the reliability objectives consistent with the PRA assumptions designed 8.3.1-25 Revision 3 - March 2007 into the plant. Reliability assurance activities for the operating stage are integrated into existing programs (e.g., maintenance rule, surveillance testing, inservice inspection, inservice testing, and quality assurance). Further detailed information and guidance on reliability assurance programs for passive COL applications are provided in Section C.III.17.4 of Regulatory Guide 1.206, SECY-94-084, and SECY-95-132. The reviewer verifies that adequate provisions are made in the design of the onsite power systems for grounding, surge protection, and lightning protection. The reviewer evaluates onsite power system grounding, ground fault current limiting features, lightning/transient surge protection features, and measures for isolation of instrumentation grounding systems. Regulatory Guide 1.204 and IEEE Stds 665, 666, 1050, and C62.23, which the regulatory guide endorses, provide acceptable guidelines for the design, installation, and performance of lightning protection systems. Guidance with respect to grounding system design and analysis criteria for COL applications that are not based on certified ALWR designs is provided in Regulatory Guide 1.206, Section C.I.8.3.1, and for those COL applications based on certified designs, in Regulatory Guide 1.206, Section C.III.1 Chapter 8. Detailed review of grounding and lightning protection for the generating station and offsite power system is provided in SRP Section 8.2. Variations in voltage,
