This conclusion is based on the following: 87 1. The applicant has met the requirements of General Design Criterion 2, "Design Bases for Protection Against Natural Phenomena," with respect to the system being capable of withstanding the effects of earthquakes by meeting the guidelines of Regulatory Guide 1.29, "Seismic Design Classification," position C.1 for safety-related portions of the system and position C.2 for nonsafety-related portions of the system. 2. The applicant has met the requirements of General Design Criterion 4, "Environmental and MissileDynamic Effects Design Basis," by appropriately addressing adverse 88 environmental conditions and dynamic effects in the design of the system to ensure its capability for maintaining environmental conditions in the control room within the design limits of the essential equipment important to safety located therein for normal, transient, or accident conditions.89 3. The applicant has met the requirements of General Design Criterion 5, "Sharing of Structures, Systems, and Components Important to Safety to Perform Required Safety Functions," with respect to capability of shared systems and components important to 90 safety to perform required safety functions. 4. The applicant has met the requirements of General Design Criterion 19, "Control Room," with respect to the capability of the system to maintain a suitable environment in the control room for occupancy during normal and accident conditions by meeting the guidelines of Regulatory Guide 1.78, "Assumptions for Evaluating the Habitability of a Nuclear Power Plant Control Room During a
