guidance when developing PDC. If electrical power is not required to permit the functioning of SSCs important to safety, the requirements in the SFR-DC are not applicable to the design. In this case, the functionality of SSCs important to safety must be fully evaluated and documented in the design bases. 18 Inspection and testing of electric power systems. Same as ARDC. Electric power systems important to safety shall be designed to permit appropriate periodic inspection and testing of important areas and features, such as wiring, insulation, connections, and switchboards, to assess the continuity of the systems and the condition of their components. The systems shall be designed with a capability to test periodically (1) the operability and functional performance of the components of the systems, such as onsite power sources, relays, switches, and buses, and (2) the operability of the systems as a whole and, under conditions as close to design as practical, the full operation sequence that brings the systems into operation, including operation of applicable portions of the protection system, and the transfer of power among systems. GDC 18 is a design-independent companion criterion to GDC 17. Wording pertaining to additional system examples has been deleted to allow increased flexibility associated with various designs. The text related to the nuclear power unit, offsite power system, and onsite power system was deleted to be consistent with ARDC 17. APPENDIX B.

A control room shall be provided from which actions can be taken to operate the nuclear power unit safely under normal conditions and to maintain it in a safe condition under accident conditions. Adequate radiation protection shall be provided to permit access and occupancy of the control room under accident conditions without
