espect 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 the system to suitably control 'release of gaseous radioactive effluents to the environment by meeting the guidelines of Regulatory Guide 1.140 "Design, Testing, and Maintenance Criteria for Normal Ventilation Exhaust System Air Filtration and Adsorption Units of Light-Water-Cooled Nuclear Power Plants," Positions C.1 and C.2. The staff concludes that the design of the TAVS conforms to all applicable GDCs and positions of the regulatory guides cited and is, therefore, acceptable. V. IMPLEMENTATION The following is intended to provide guidance to applicants and licensees regarding the NRC staff's plans for using this SRP section. Except in those cases in which the applicant proposes an acceptable alternative method for complying with specified portions of the Commission's regulations, the method described herein will be used by the staff in its evaluation of conformance with Commission regulations. Implementation schedules for conformance to parts of the method discussed herein are contained in the referenced regulatory guides. VI.
