C 2 are satisfied for the facility being considered, the organization responsible for civil engineering and geosciences review should provide to the organization responsible for electrical engineering review, upon request, information on the design basis, high and low atmospheric temperatures, high wind, rain, lightning discharges, ice and snow conditions, and weather events causing regional effects. This information should be considered during the review to verify that the design minimizes the effects of these conditions in accordance with GDC 17. Items such as switchyard and transformer locations, transformer cooling, overhead transmission lines, underground or inaccessible power and control cables could be affected by these conditions. Operating experience provides additional information on the effects of severe heat and cold on electrical system equipment (References 23 and 28) and on the effects of protracted submergence and wet environments on underground electric cables (Reference 26). Communication links between the plant operators and local TSO/ISOs serve as a means to obtain timely information on power grid operating conditions and status to verify the operability of the offsite power grid in accordance with the requirements of the plant=s technical specifications. Communications with offsite entities are also important for 8.2-23 Revision 5 - May 2010 restoration of offsite power in the event of a LOOP or SBO. The plant=s offsite communications equipment and protocols, communication contingency procedures, communications circuit routing, and telemetry links used to monitor the power grid and to verify and maintain grid stability and operability should be reviewed to determine that they are secure and will continue to function during severe weather events causing regional effects. Operating experience provides additional information on offsite communications capability and integrity during severe weather events (Reference 22). 6. To ensure that the
