sign Criterion GDC 17 is provided, the immediately available preferred circuit must be made available to the redundant portions of these systems. 4. It should be determined that all equipment from and including the switchyard to the onsite Class 1E system are is appropriately included in the quality assurance program. 72 The QABHQMB will determine the adequacy of the quality assurance program. 73 5. To assure ensure that the requirements (excluding seismic, tornado, and floods) of General Design Criterion 2 (GDC 2) are satisfied for the facility being considered, the 74 Environmental and Hydrologic Engineering Branch (EHEBECGB) will provide to 75 PSBEELB upon request information on the design basis, high and low atmospheric 76 temperatures, high wind, rain, ice, and snow conditions. This information will be considered during the review to assure ensure that the design minimizes in accordance with GDC 17 the effects of these conditions. Items such as switchyard and transformer locations and associated transmission lines could be affected by these conditions. 6. To assure ensure that the requirements of General Design Criterion 4 are satisfied, the ASBSPLB, on request, will review the location of structures, systems, and components 77 of the preferred power system to determine the protection provided against dynamic effects, including effects of missiles, pipe whipping, and discharging fluids, that may result from equipment failures and from events and conditions outside the station. This information will be used to determine the possibility of simultaneous loss of both paths of preferred power. 7. To assure ensure that the requirements of General Design Criterion GDC 5 are satisfied, the structures, systems, and components of the preferred power systems will be examined to identify any that are shared between units of a multi-unit station. These will be reviewed to ascertain that they have sufficient capacity and capability of performing all required safety functions
