f this guidance should ensure that the GWMS will continue to perform its safety functions under postulated accident conditions and meet the requirements of GDC 2 and Part 20. RG 1.143 describes design guidance acceptable to the staff related to seismic, safety, and quality group classifications and quality assurance provisions for SSCs systems of the GWMS for gaseous wastes and effluents produced during normal operation and AOOs. RG 1.143 provides guidance in assigning safety classifications to structures and radioactive waste management systems in protecting SSCs against natural phenomena and man-induced hazards. For unmitigated releases of radioactive materials, the acceptance criterion of RG 1.143 is 1 mSv (100 mrem) for members of the public assumed to be located at or beyond the restricted area or in unrestricted areas (whichever is most limiting). For unmitigated radiation exposures to site personnel, the acceptance criterion is 5 rem (50 mSv) for a plant worker assumed to be located in the restricted area. In classifying system components, the radioactivity inventories of components are compared to the acceptance criteria in determining the appropriate safety classification. In addition, RG 1.206, Part I, C.I.3, Sections 3.2.1 and 3.2.2, and SRP Section 3.8.4 identify applicable acceptance criteria in evaluating SSCs requiring seismic design considerations and discuss differences from the recommendations of RG 1.143. Meeting the guidance of RG 1.143 provides reasonable assurance that the assigned safety classifications for structures housing the GWMS and its components comply with the requirements of GDC 2 and 61 and the guidance of RG 1.143 for natural phenomena and man-induced hazards. Meeting the guidance of SRP Section 11.3 and BTP 11-5 (as referenced herein), and using the analysis of RG 1.143 in assigning the safety classifications to SSCs of the GWMS for design purposes, provide reasonable assurance that the necessary information is available to
