tem connects to the gaseous cleanup and treatment system or station vents. All portions of the system whose failure may result in release of radioactivity which causes an offsite dose of more than 0.5 rem to the whole body or its equivalent to any part of the body shall be classified seismic Category I and safety related. Based on the review of the applicant's proposed design criteria, design bases, and safety classification for the auxiliary and radwaste area ventilation system and the requirements for system performance to preclude an unacceptable release of contaminants to the environment during normal, abnormal, and accident conditions, the staff concludes that the design of the auxiliary and radwaste area ventilation system and auxiliary supporting systems is in conformance with the Commission's regulations as set forth in General Design Criterion 2, "Design Bases for Protection Against Natural Phenomena," General Design Criterion 5, "Sharing of Structures, Systems, and Components," and-General Design Criterion 60, "Control of Releases of Radioactive Materials to the Environment." This conclusion is based on the following: 1. The applicant has met the requirements of GDC 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. 9.4.3-5 Rev. 2 - July 1981 2. The applicant has met the requirements of GDC 5, "Sharing of Structures, Systems, and Components Important to Safety to Perform Required Safety Function," with respect to capability of shared systems and components important to safety to perform required safety functions. 3. The applicant has met the requirements of GDC 60, "Control of Releases of Radioactive Materials to the Environment," with respect to the capability of
